Non-destructive Testing Services Market (2026-2036)

The growth of this market is mainly driven by pipeline integrity regulation covering more than 500,000 miles of United States pipelines with compliance obligations extending over decades, assets operated beyond their original design life that require more frequent inspection, turnaround and call-out activity in oil, gas and refining, process safety enforcement programmes, and the obligation for integrity records to be reliable, traceable, verifiable and complete. However, the shortage of certified technicians, the capital intensity and leverage carried by service providers, pricing pressure in competitive tender markets, and the maturity of the largest end markets restrain the growth of this market.

Beyond these, inspection data management and reporting services, remote and robotic inspection, digital radiography replacing film, corrosion and erosion mapping on life-extended assets, and outcome-based asset integrity management contracts are expected to create significant growth opportunities for the stakeholders in this market.

Non-destructive testing services are the inspection, evaluation and associated technical services through which the condition and integrity of materials, welds, components and structures are assessed without impairing their future usefulness. The scope covers field and shop inspection delivered by certified technicians; calibration and evaluation services; training and personnel certification; equipment rental; consulting and engineering assessment including fitness-for-service and remaining-life evaluation; and inspection data management and reporting. Methods in scope include ultrasonic testing in its conventional, phased array, time-of-flight diffraction, long-range and automated forms, radiographic testing in conventional, computed and digital forms, electromagnetic methods including eddy current, remote field, alternating current field measurement and magnetic flux leakage, magnetic particle and liquid penetrant testing, visual and remote visual inspection, acoustic emission monitoring and positive material identification. Pipeline inline inspection is in scope because magnetic flux leakage and long-range ultrasonic methods are the techniques it applies. On this basis the market was valued at USD 14.20 billion in 2025, is estimated at USD 15.10 billion in 2026 and is forecast to reach USD 29.70 billion by 2036 at a CAGR of 7.0%, against approximately USD 9.90 billion in 2024 and above USD 18.58 billion by 2031 on the narrower basis used previously. Excluded are sales of inspection instruments and consumables, destructive mechanical and metallurgical laboratory testing, and inspection performed by asset owners using their own captive personnel.

The ecosystem divides into four supplier groups and one demand group. Diversified testing, inspection and certification companies including SGS, Bureau Veritas, Intertek, Applus Services, TUV SUD, TUV Rheinland, DEKRA and Element Materials Technology deliver non-destructive testing within broader compliance portfolios. Specialist asset protection providers including MISTRAS Group, Team, TIC Solutions and Applied Technical Services derive the majority of revenue from field inspection and the adjacent mechanical services that follow from it. Pipeline inline inspection specialists including the ROSEN Group, NDT Global and T.D. Williamson operate in-line tools that apply magnetic flux leakage and ultrasonic techniques across transmission networks. Classification and certification societies including Lloyd's Register, DNV, RINA and Kiwa combine survey, certification and inspection, principally in marine, energy and infrastructure. Demand comes from oil and gas operators, refiners and petrochemical producers, power generators, pipeline operators, infrastructure authorities, aerospace primes and their supply chains, and marine operators, with inspection procured through call-out arrangements, turnaround campaigns and multi-year framework agreements. The scale of the specialist group is visible in reported results: MISTRAS recorded 2025 revenue of USD 724.0 million with approximately 4,800 employees, Team recorded USD 896.5 million including USD 458.9 million in Inspection and Heat Treating, and TIC Solutions guided full-year 2025 service revenue of USD 1,530.0 million to USD 1,565.0 million.

This is a labour-delivered market in which the unit of sale is a certified technician hour against an approved procedure, which determines both the economics and the constraints. Reported margins sit in a narrow band: MISTRAS recorded 2025 gross profit of USD 204.5 million at a 28.2% margin and adjusted EBITDA of USD 91.1 million at 12.6%, while Team recorded gross margin of 25.8% of revenue and adjusted EBITDA of 6.8%, and TIC Solutions guided full-year 2025 adjusted EBITDA of USD 240.0 million to USD 250.0 million on service revenue of USD 1,530.0 million to USD 1,565.0 million. Providers carry meaningful leverage against those margins, with MISTRAS reporting net debt of USD 150.0 million at approximately 2.5 times a bank-defined ratio against a 3.75 times maximum, and Team reporting net debt of USD 279.1 million after a March 2025 refinancing and a September 2025 preferred issue raising USD 75.0 million. Customer concentration is moderate, with the top ten customers representing about 36% of revenue at MISTRAS in both 2025 and 2024.

Three layers of obligation generate demand, and they differ in how binding they are. Statutory regulation is the strongest: the Pipeline and Hazardous Materials Safety Administration rule of October 2019 expanded integrity requirements to more than 500,000 miles of United States pipelines, with some requirements expected to take operators decades to satisfy, and requires integrity records to be reliable, traceable, verifiable and complete; the Occupational Safety and Health Administration operates a National Emphasis Program on process safety. Industry codes form the second layer, including the American Petroleum Institute inspection codes governing pressure vessels, piping and above-ground storage tanks, American Society of Mechanical Engineers boiler and pressure vessel requirements, and welding codes, which set inspection intervals and acceptance criteria that operators follow to maintain insurability and operating authorisation. Personnel certification forms the third layer, under which technicians qualify to recognised written-practice schemes by method and level, and aerospace work additionally requires laboratory accreditation under Nadcap and AS9100.

North America holds the largest position. The concentration is visible in provider disclosure, with North America representing approximately 81% of 2025 revenue at the largest listed pure-play, against 81% in 2024 and 82% in 2023, supported by the October 2019 pipeline integrity rule covering more than 500,000 miles, refinery and petrochemical turnaround cycles, and an outsourcing culture in which operators retain third parties rather than captive inspection departments. Asia-Pacific is the second region by value and the largest by physical inspection volume, with activity concentrated in Chinese power generation and construction, Indian refining and infrastructure, Japanese and South Korean shipbuilding and Australian mining and energy, at materially lower price per technician hour. Europe follows, with inspection delivered largely through the diversified testing, inspection and certification companies and the classification societies headquartered there. The Middle East & Africa is projected to grow fastest on Gulf oil, gas and petrochemical capital programmes, and Latin America is led by Brazilian upstream and refining activity.

The strongest demand driver in this market is statutory rather than commercial, and it runs for decades rather than quarters. The Pipeline and Hazardous Materials Safety Administration rule issued in October 2019 expanded pipeline integrity requirements to more than 500,000 miles of United States pipelines, and some of its requirements are expected to take operators decades to satisfy. Critically, the rule requires integrity records to be reliable, traceable, verifiable and complete, which converts inspection from a field activity into an auditable data obligation and generates demand for inspection and data services together rather than separately. The Occupational Safety and Health Administration operates a National Emphasis Program on process safety alongside it. Because the obligation attaches to mileage already in the ground rather than to new construction, the demand is insensitive to the capital expenditure cycle and persists through commodity price downturns, which is why regulatory-mandated inspection is the fastest-growing inspection driver segment.

The demand base in this market is asset age, not asset addition. Provider disclosure states that many customers operate assets beyond their original design life, which requires ongoing inspection, testing and monitoring, and that aged assets require more frequent inspection and maintenance than new ones, so owners continue spending on asset protection. The mechanism is that inspection intervals under industry codes shorten as measured wall loss, crack indications and remaining-life calculations deteriorate, so a life-extended asset consumes more inspection hours each cycle than the same asset did when new. This is also why corrosion and erosion mapping grows faster than flaw detection on new fabrication: the question on an ageing asset is not whether a defect exists but how fast the wall is thinning and when the asset must be repaired, replaced or derated. The effect compounds, because every extension decision requires a fitness-for-service assessment supported by fresh inspection data. The scale is set by the installed base rather than by new build: the October 2019 pipeline integrity rule alone applies to more than 500,000 miles of United States pipelines, and oil and gas represented 55% of 2025 revenue at the largest listed pure-play provider, where North America accounted for approximately 81%.

Growth in 2025 came from maintenance activity rather than construction, which confirms where this market actually earns. Team attributed Inspection and Heat Treating growth of 7.5% to USD 458.9 million to higher United States call-out and turnaround activity together with expanded project work at its Cincinnati laboratory, and recorded a USD 14.6 million increase in United States turnaround work in oil and refining within its Mechanical Services segment, alongside increased non-destructive examination and heat-treating activity in Canada. The same disclosure shows the counterweight: international Mechanical Services revenue fell USD 9.9 million on reduced call-out and leak repair project activity. Turnaround work is attractive to providers because it is scheduled, dense in man-hours and priced on availability rather than on competitive tender, and it is attractive as a forecasting basis because refinery and petrochemical turnaround cycles are planned years ahead on fixed intervals.

What the customer buys has shifted from a finding to an auditable record, which creates a service line that did not previously exist. The October 2019 pipeline integrity rule requires records to be reliable, traceable, verifiable and complete, which means an inspection is not complete when the technician leaves site but when the data is reconciled, located against the asset, validated and retained in a form that survives a regulatory audit. MISTRAS has responded by investing in digital inspection capabilities and data integrity, cited by its executive chairman as a strategic priority, while describing 2026 as a targeted year focused on investment. For providers the attraction is that data services carry software-like margins against the roughly 25.8% to 28.2% gross margins reported on field services, do not require additional certified technicians, and create switching costs once an operator integrity database is hosted and maintained by a provider.

The structural reason this is a services market rather than an equipment market is that the dominant end users do not perform their own inspection. The annual report of the largest listed pure-play provider states that oil and gas represented 55% of its 2025 revenue, with the top ten customers accounting for about 36% of revenue in 2025 and 2024 and no single customer exceeding 10%. Operators outsource because inspection demand is campaign-driven rather than continuous, because certification currency must be maintained by method and level across a large technician population, and because third-party status carries evidentiary weight with regulators and insurers. Manufacturing inspection, by contrast, is predominantly performed in-house with owned equipment and resident certified staff on continuous production lines, which is why a manufacturing-led end-use ranking describes an equipment market rather than a services market.

Capacity in this market is a function of qualified people, and it cannot be expanded faster than certification allows. MISTRAS identifies the inability to attract and retain certified technicians, engineers and scientists as a principal risk factor against a workforce of approximately 4,800 employees, and Team cited labour-related costs as a quarterly timing factor within its Inspection and Heat Treating results. The constraint is structural because a non-destructive testing result is only valid when produced by an individual certified to a recognised written practice at the required level for that method, and because aerospace work additionally requires laboratory accreditation under Nadcap and AS9100. Certification requires documented training hours, examination and supervised experience by method, so a provider cannot convert a won framework agreement into revenue by hiring alone. This both caps growth and supports pricing, which is part of why the 2025 results show margin expansion of 130 to 190 basis points on revenue growth between approximately zero and 5.2%.

Providers in this market carry debt against single-digit to low-double-digit margins, which constrains how much capability they can fund. MISTRAS reported 2025 gross debt of USD 178.0 million against USD 169.6 million at the end of 2024, net debt of USD 150.0 million, leverage of approximately 2.5 times under its bank-defined ratio against a 3.75 times maximum, and free cash flow of USD 3.8 million against USD 27.1 million in 2024, with operating cash flow falling to USD 33.0 million from USD 50.1 million on higher receivables and capital expenditure. Team reported total debt of USD 297.2 million and net debt of USD 279.1 million with total liquidity of USD 77.4 million, following a March 2025 refinancing that lowered its blended interest rate by more than 100 basis points and a September 2025 preferred stock and warrant issue raising USD 75.0 million, and recorded negative free cash flow of USD 20.6 million against positive USD 13.3 million in 2024, alongside a net loss of USD 49.2 million.

Below the top tier this market is highly fragmented, and inspection work is frequently awarded on price per technician hour against a specified procedure, which limits what differentiation can earn. The commercial consequence is visible in how providers describe their gains: Team attributed its adjusted EBITDA improvement to a more favourable job and pricing mix together with cost reductions rather than to rate increases, and reported adjusted selling, general and administrative expense of USD 183.7 million at 20.5% of revenue, down 90 basis points, indicating that cost discipline rather than price carried the margin. MISTRAS improved its gross margin 190 basis points to 28.2% while revenue was effectively flat and voluntarily consolidated USD 7.0 million of laboratory revenue, which is a mix and footprint decision rather than a pricing one. Where an operator can qualify 3 or 4 providers to the same procedure, rate escalation is difficult outside the specialist methods and outside turnaround availability pricing.

The end markets that generate the majority of demand are mature and are not adding capacity at a rate that would support high single-digit or double-digit growth. Oil and gas represented 55% of 2025 revenue at the largest listed pure-play, and demand there derives from maintaining an installed base rather than from building new refining, pipeline or processing capacity in the developed markets where third-party inspection is most heavily outsourced. North America, which represented approximately 81% of that provider revenue in 2025, is the most mature of all. Growth therefore depends on inspection intensity per asset, on regulatory tightening and on pricing, rather than on asset population growth, which is the reason the sector grew between approximately zero and 5.2% in 2025 while expanding margins. Geographic expansion into Gulf capital programmes and Asian industrialisation offsets this only partially, because price per technician hour is materially lower outside the mature markets.

The regulatory requirement that integrity records be reliable, traceable, verifiable and complete has created a service the preceding market structure did not recognise at all. The opportunity covers asset register reconciliation, inspection data location and tagging, corrosion-rate trending across inspection histories, remaining-life calculation, audit-ready retention and operator integrity database hosting. Its commercial attraction is threefold: it carries higher margin than the 25.8% to 28.2% gross margins reported on field inspection, it does not consume scarce certified technician hours, and it creates switching costs once an operator integrity dataset is maintained by the provider that generated it. MISTRAS has positioned explicitly here, with its executive chairman citing investment in digital inspection capabilities and data integrity and the board describing 2026 as a targeted year focused on investment. For the sector this converts a project-based business into a recurring one.

Remote and robotic delivery addresses the two binding constraints in this market simultaneously, which is why it grows faster than the field inspection it supplements. Crawlers, drones, remotely operated vehicles and permanently installed monitoring sensors reduce the certified technician hours required per asset inspected, which relieves the workforce constraint, and they remove personnel from confined spaces, elevated work and live plant, which addresses the safety exposure that process safety enforcement programmes target. They also enable inspection of assets that cannot be taken out of service, shifting work from scheduled turnaround windows into in-service monitoring and smoothing the seasonality that makes turnaround-dependent revenue lumpy. Pipeline inline inspection is the most mature expression of this, applying magnetic flux leakage and ultrasonic techniques across networks that cannot be opened, and its relevance to this market follows directly from those methods being within the stated method scope, applied across the more than 500,000 miles of United States pipelines covered by the October 2019 integrity rule. For providers operating at gross margins of 25.8% to 28.2% with net debt of USD 150.0 million to USD 279.1 million, robotic delivery raises output per certified technician without adding to a workforce of approximately 4,800 that is already difficult to recruit.

The fastest-growing application in this market follows from the ageing of the asset base rather than from any technology change. Where customers operate assets beyond their original design life, the inspection question changes from whether a defect is present to how quickly material is being lost and when intervention is required, which demands repeatable quantitative mapping rather than pass-or-fail flaw detection. The deliverable is a wall-thickness grid referenced to fixed locations and trended across inspection cycles, which supports fitness-for-service assessment, remaining-life calculation and the derating or replacement decision. Commercially this is attractive because it is inherently repeat business on a defined interval rather than one-time project work, because it generates the inspection history that data management services then monetise, and because it applies across piping, pipelines, pressure vessels and storage tanks, which together constitute the largest asset categories in the market. The demand base is substantial: more than 500,000 miles of United States pipelines fall under the October 2019 integrity rule, oil and gas represented 55% of 2025 revenue at the largest listed pure-play, and inspection intervals under industry codes shorten by 2 or 3 cycles as measured wall loss accumulates.

Moving from hourly rates to contracted integrity outcomes is the principal route out of competitive tender pricing. Under an outcome-based structure the provider is retained to maintain a defined integrity position across a specified asset population, taking responsibility for inspection planning, interval setting, execution, data management and reporting, and is paid against availability and compliance rather than against hours delivered. The attraction to the operator is that it transfers the certification, scheduling and record-keeping burden created by the October 2019 pipeline integrity rule to a party that specialises in it. The attraction to the provider is multi-year revenue visibility, margin set by efficiency rather than by rate, and incumbency that is difficult to tender against. TIC Solutions names industrials, energy processing, utilities and public and commercial infrastructure as core markets with additional exposure to data centres, aviation, healthcare and higher education, which is the asset breadth such contracts require.

Demand created by regulation is not automatically convertible into revenue, because the delivery mechanism is a certified person. The October 2019 pipeline integrity rule covers more than 500,000 miles of United States pipelines with requirements expected to take operators decades to satisfy, which is a demand pool far larger than sector delivery capacity, yet MISTRAS at approximately 4,800 employees identifies technician attraction and retention as a principal risk and recorded effectively flat revenue of USD 724.0 million in 2025. The resolution available to providers is to raise output per technician hour through robotic delivery, permanently installed monitoring and automated data handling rather than to recruit at scale, which is an investment decision made against free cash flow of USD 3.8 million and net debt of USD 150.0 million. The sector is therefore capacity-constrained in a demand-rich market, which explains margin expansion alongside flat volume.

What providers are asked to inspect is becoming harder to inspect, which raises qualification cost per contract. Composite and bonded structures in aerospace and in renewable energy components do not respond to the magnetic and conventional ultrasonic techniques developed for carbon steel, requiring phased array, air-coupled and thermographic approaches with their own procedures and operator qualifications. Additively manufactured and dissimilar-metal components present internal geometries and grain structures that complicate signal interpretation. High-temperature and insulated plant requires inspection through coatings and cladding without removal. Each of these demands method-specific procedure development, equipment investment and separate operator certification, against sector gross margins of 25.8% to 28.2% and the leverage positions providers already carry. The commercial consequence is that specialist method capability concentrates among providers large enough to fund it, which accelerates consolidation of the kind represented by the Acuren merger with NV5.

Revenue in this market arrives in campaigns, and the resulting volatility complicates both operations and valuation. Team recorded a USD 14.6 million increase in United States turnaround work in oil and refining while international Mechanical Services revenue fell USD 9.9 million on reduced call-out and leak repair activity, and cited labour-related costs as a quarterly timing factor; it also declined to issue 2026 guidance following a leadership change, pending first-quarter results. MISTRAS saw operating cash flow fall to USD 33.0 million from USD 50.1 million and free cash flow to USD 3.8 million from USD 27.1 million on working capital timing and higher capital expenditure, despite record adjusted EBITDA of USD 91.1 million. Because certified technicians must be retained between campaigns to remain available for them, utilisation troughs are carried as fixed cost, which is why providers are pursuing in-service monitoring, data services and multi-year framework agreements that bill independently of turnaround windows.

The defining commercial pattern of this market is that providers are earning more on roughly the same volume. MISTRAS recorded 2025 revenue of USD 724.0 million, effectively flat after excluding USD 7.0 million of voluntary laboratory consolidations, while lifting gross profit to USD 204.5 million at a 28.2% margin, up 190 basis points, and adjusted EBITDA to a record USD 91.1 million, up 10.5%, at a 12.6% margin, up 130 basis points. Team grew revenue 5.2% to USD 896.5 million while lifting adjusted EBITDA 11.9% to USD 60.7 million at 6.8% from 6.4%, with adjusted selling, general and administrative expense down 90 basis points to 20.5% of revenue, attributing the gain to job and pricing mix together with cost reductions. The forecasting implication is that the market compounds through intensity, mix and rate rather than through volume.

What operators buy has changed, and the change was made by regulation rather than by suppliers. The October 2019 pipeline integrity rule requires integrity records to be reliable, traceable, verifiable and complete across more than 500,000 miles of United States pipelines, with some requirements expected to take operators decades to satisfy, which means an inspection is complete only when the data is reconciled to the asset, validated and retained in audit-ready form. MISTRAS has positioned against this, with its executive chairman citing investment in digital inspection capabilities and data integrity while the board describes 2026 as a targeted year focused on investment. The consequence is a service line that the preceding market structure did not recognise, carrying higher margin than the 25.8% to 28.2% gross margins reported on field inspection and consuming no additional certified technician hours.

This market is demand-rich and delivery-constrained, which is unusual and shapes everything about pricing and investment. The regulatory demand pool covers more than 500,000 miles of United States pipelines on a multi-decade compliance timetable, yet MISTRAS at approximately 4,800 employees reported effectively flat 2025 revenue and identifies the inability to attract and retain certified technicians, engineers and scientists as a principal risk, while Team cited labour-related costs as a quarterly timing factor. Because a valid result requires an individual certified by method and level against an approved written practice, and aerospace work additionally requires Nadcap and AS9100 laboratory accreditation, capacity cannot be bought. Providers are therefore investing in output per technician hour through robotic delivery, permanent monitoring and automated data handling, against free cash flow of USD 3.8 million at MISTRAS and negative USD 20.6 million at Team.

Growth in this market tracks turnaround and call-out schedules rather than capital projects, which makes it steadier than construction-linked service markets. Team attributed Inspection and Heat Treating growth of 7.5% to USD 458.9 million to higher United States call-out and turnaround activity with expanded laboratory project work, recorded a USD 14.6 million increase in United States turnaround work in oil and refining within Mechanical Services and increased non-destructive examination and heat-treating activity in Canada, against a USD 9.9 million decline in international call-out and leak repair activity. Because customers operate many assets beyond original design life and aged assets require more frequent inspection than new ones, spending continues through capital expenditure downturns. Refinery and petrochemical turnaround cycles are also planned years ahead on fixed intervals, which gives the revenue base visibility that project work does not.

The largest providers are combining to fund specialist method capability and to widen framework coverage. Acuren completed a merger with NV5 and changed its name to TIC Solutions, Inc. with effect from 10 October 2025, retaining Acuren, NV5 and other legacy names as customer-facing brands, continuing to trade under the ticker TIC and relocating its headquarters to Hollywood, Florida, with full-year 2025 service revenue guided to USD 1,530.0 million to USD 1,565.0 million and adjusted EBITDA to USD 240.0 million to USD 250.0 million. Its executive chairman stated that meaningful synergies in cost and in go-to-market strategy would be apparent in 2026 and beyond. The driver is that composite, additive and high-temperature inspection each require separate procedure development, equipment and operator certification, which only providers of scale can fund against sector gross margins of 25.8% to 28.2%.

Based on service type, the market is segmented into inspection services, calibration and evaluation services, training and certification services, equipment rental services, consulting and engineering services, and data management and reporting services. In 2026, the inspection services segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to field and shop inspection man-hours being the product in a services market, delivered by certified technicians against approved procedures, as reflected in provider revenue such as the USD 458.9 million Inspection and Heat Treating segment at Team. However, the data management and reporting services segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to the October 2019 pipeline integrity rule requiring records to be reliable, traceable, verifiable and complete across more than 500,000 miles, and to provider investment in digital inspection and data integrity capability.

Based on method, the market is segmented into ultrasonic testing, radiographic testing, electromagnetic testing, magnetic particle testing, liquid penetrant testing, visual and remote visual testing, acoustic emission testing, and other methods. In 2026, the ultrasonic testing segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to its application across piping, pipelines, pressure vessels and storage tanks for wall-thickness measurement and weld examination, and to the breadth of its variants including phased array, time-of-flight diffraction, long-range and automated forms. However, the radiographic testing segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to the transition from conventional film to computed and digital radiography, which removes chemical processing, shortens turnaround to minutes and produces the digital record that audit-ready integrity documentation requires.

Based on application, the market is segmented into flaw detection and defect characterisation, weld integrity verification, corrosion and erosion mapping, dimensional and thickness measurement, material verification and chemical composition determination, and stress and structural analysis. In 2026, the flaw detection and defect characterisation segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to its application across every method and every end-use industry as the baseline acceptance test under industry codes. However, the corrosion and erosion mapping segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to customers operating assets beyond original design life, where aged assets require more frequent inspection than new ones, and to the shift from pass-or-fail testing toward repeatable quantitative wall-loss trending that supports fitness-for-service and remaining-life assessment.

Based on end-use industry, the market is segmented into oil and gas, power generation, public infrastructure, aerospace and defence, manufacturing and industrials, chemicals and petrochemicals, marine and shipping, rail and transportation, water and waste management, and other end-use industries. In 2026, the oil and gas segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to outsourced inspection being standard operator practice, with oil and gas representing 55% of 2025 revenue at the largest listed pure-play provider. However, the power generation segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to life extension of existing generating plant, grid and transmission build-out, and new load from data centres, which TIC Solutions names among its exposures alongside utilities.

Based on asset type, the market is segmented into piping and pipelines, pressure vessels and boilers, storage tanks and terminals, welds and structural steel, rotating equipment, castings and forgings, civil structures, and composite structures. In 2026, the piping and pipelines segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to the October 2019 integrity rule covering more than 500,000 miles of United States pipelines with compliance extending over decades, and to the density of piping circuits within refining and petrochemical plant. However, the composite structures segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to composite and bonded assemblies in aerospace and renewable energy components, which do not respond to magnetic or conventional ultrasonic techniques and require phased array, air-coupled and thermographic methods with separate procedures and operator qualifications.

Based on deployment mode, the market is segmented into on-site field inspection, in-service and online inspection, laboratory and shop inspection, and remote and robotic inspection. In 2026, the on-site field inspection segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to the location of the asset base in operating plant, pipelines and infrastructure that cannot be transported, and to turnaround and call-out work being delivered on the customer site. However, the remote and robotic inspection segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to crawlers, drones, remotely operated vehicles, permanently installed monitoring and pipeline inline inspection tools raising output per certified technician hour against a workforce of approximately 4,800 at the largest listed provider that is identified as difficult to recruit, and to the removal of personnel from confined, elevated and live-plant exposure.

Based on contract model, the market is segmented into call-out and time-and-materials work, turnaround and shutdown campaigns, long-term framework and master service agreements, and outcome-based asset integrity management. In 2026, the call-out and time-and-materials segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to the unscheduled nature of much inspection demand, with Team attributing Inspection and Heat Treating growth of 7.5% to higher United States call-out and turnaround activity. However, the outcome-based asset integrity management segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to operators transferring the certification, scheduling and record-keeping burden created by the October 2019 integrity rule to specialist providers, and to providers seeking margin set by efficiency rather than by hourly rate in a market where 3 or 4 suppliers are commonly qualified to the same procedure.

Based on inspection driver, the market is segmented into code-driven inspection, regulatory-mandated inspection, insurance and certification-driven inspection, and owner-elected condition monitoring. In 2026, the code-driven inspection segment is expected to account for the largest share of the global Non-destructive Testing Services Market. The large share of this segment is mainly due to American Petroleum Institute inspection codes for pressure vessels, piping and above-ground storage tanks, American Society of Mechanical Engineers boiler and pressure vessel requirements and welding codes, which set intervals and acceptance criteria across the installed base. However, the regulatory-mandated inspection segment is projected to register the fastest growth during the forecast period. The rapid growth of this segment is attributed to the October 2019 pipeline integrity rule extending requirements to more than 500,000 miles of United States pipelines with multi-decade compliance timetables and traceable record obligations, alongside the process safety National Emphasis Program.
