API 570 Piping Inspection Services (NDT) for Process & Industrial Systems

Dexon Technology brings over 45 years of inspection experience and a highly certified workforce to piping systems governed under American Petroleum Institute (API) 570. 

Process piping systems are critical to safe and efficient operations across refineries, petrochemical plants, and industrial facilities. Continuous exposure to pressure, temperature variation, and corrosive media can lead to corrosion, erosion, cracking, and wall thinning. 

Dexon’s non-destructive testing (NDT) services enable operators to detect early-stage defects and maintain compliance with API 570 requirements, supporting safe operation, regulatory compliance, and asset integrity management.

Inspection Techniques & Capabilities 

Dexon applies a combination of ultrasonic, electromagnetic, and visual inspection methods to assess piping integrity in accordance with API 570 inspection requirements.

Access Solutions for Difficult-to-Reach Piping Systems 

Difficult-to-reach piping systems, such as elevated pipe racks, congested units, and insulated lines, can be inspected using rope access or drone-based methods.  

Rope access (IRATA) enables direct application of UT, PAUT, and PEC on elevated assets without scaffolding 

Drone-based inspection supports rapid visual screening and can integrate UT or ECT sensors for targeted thickness measurement and defect detection in inaccessible areas.
