How to perform non-destructive testing on the socket welds between the main pipes and branch pipes in pressure pipelines
Thread Content
I would like to ask how non-destructive testing can be carried out on the socket welds between the main pipes and branch pipes in pressure pipelines; can RT be used? Pipe material 2507
Check the structure to see whether it has direct openings, or if there are branch pipe supports. The welds between the branch pipe supports and the main pipe can only be colored; ultrasonic testing does not yield good results for them
You mean the socket weld, right? It can be inspected using magnetic particle testing and dye penetrant testing, but only for surface cracks. If it is difficult to detect internal defects, special ultrasonic probes can be used (since 2507 is a duplex stainless steel, ordinary probes will not work), or fake parts can be fabricated for radiographic inspection.
It is a socket weld joint, without a branch pipe base~
Can’t do RT, MT, or PT
