Evaluating pipe damage
Evaluating pipe damage
(OP)
I have a 36" pipe that was "bumped" and now has a clearly visible dent. The pipe is used in an above-ground in-plant petroleum storage terminal. The operating pressure is 100 psig. What forms of inspection are appropriate? What codes might help provide guidance on acceptability? ASME B31.3 offers limited help. Thanks!!

Can you comeback with the size of the dent?
What is the material and schedule of the pipe?

You can use it for general guidance. The dents and gouges are more applicable for shells.
RE: Evaluating pipe damage
Although I would lean towards API-579 / ASME FFS-1, another resource for you would be B31.G.
