Engineering Case
Long-distance oil and gas pipelines
During inspections of long-distance oil and gas pipeline projects, the company focuses on the pipeline itself and its ancillary facilities. Using technologies such as radiographic testing, ultrasonic testing, TOFD, PA, and DR, the company inspects pipeline welds and parent materials to identify various defects. This provides comprehensive nondestructive testing support for the construction quality and operational safety of long-distance oil and gas pipelines, safeguarding the safety of these energy transportation arteries.
