ADVANCED COATING ASSESSMENT
Innovative Approach to Detect and Classify Coating Defects
CHALLENGE
Underground pipeline coating inspections can be challenging, costly, and heavily reliant on soil conditions, operator expertise, and accessibility. Standard methods may prove inadequate in situations with extremely dry soil, lack of cathodic protection, difficult access, or complex areas like compressor stations with galvanic connections to other infrastructure.
SOLUTION
Current Magnetometry Inspection (CMI) revolutionizes coating defect detection with high-resolution capabilities and precise sizing. CMI offers seamless pipeline coating inspections using a 1 cm measurement grid, independent of ground conditions, and requiring no direct contact with the ground.
CMI provides accurate coating data irrespective of coating type, cathodic protection installation, or area accessibility. It not only locates coating defects but also effectively classifies them. Our Coating Assessment service is perfect for clients with limited or no information about their pipeline's coating condition, offering valuable insights to maintain their infrastructure.
KEY POINTS
- Mitigate external corrosion risks
- Conduct seamless GPS-based pipeline coating inspections
- Independence from ground conditions
- Distinguish between metal loss and coating failure
