Predictive maintenance technologies appear in 64 percent of industrial companies. Oil and gas demand generates the largest incremental NDT spend increases across North America. Standards such as EN ISO 9712 for personnel qualification and API 510 for pressure vessel inspection continue to set required practices.
Key Takeaways
- Demand growth in oil & gas drives the largest incremental NDT spend in North America (Precedence Research discussion of end-use drivers)
- Market for NDT in aerospace is projected to grow at the fastest rate in the end-use segment in the 2024–2032 period (Fortune Business Insights segmentation)
- Asia-Pacific held 25% of the NDT market in 2023 (by region share in market segmentation)
- EN ISO 9712 provides requirements for the qualification and certification of NDT personnel (standards adoption measured as formal certification framework across sectors)
- EN ISO 17635 specifies general requirements for NDT of welds (standards adoption measured as mandated NDT framework for welding inspections)
- EN ISO 18563 specifies ultrasonic testing of welds (standards adoption measured as codification of specialized UT methods for welded joints)
- 0.5–2.0% reduction in corrosion-related costs achievable via improved inspection and maintenance planning (as quantified in corrosion management guidance based on industry case studies)
- 98% detection rate of surface cracks reported in a laboratory evaluation of eddy current testing under specified conditions (as reported in peer-reviewed study)
- 95% confidence achievable for internal defect sizing in ultrasonic testing using model-based signal processing (as quantified in peer-reviewed paper)
- Outage costs for major refinery turnarounds can exceed $1 million per day (quantified in industry reporting; NDT used to minimize outage duration)
- Predictive maintenance can cut maintenance costs by 10–40% (quantified in industry research synthesis)
- Employing corrosion inspection and data-driven risk ranking can reduce failure-related costs by 25–50% over planning horizons (quantified in corrosion risk management analyses)
North America’s oil and gas growth and faster aerospace demand are boosting NDT adoption alongside digital methods.
