Leakage pathways of pipe ends in ASME
Thread Content
What exactly are the leakage pathways for pipe fittings in ASME, and how should they be calculated? Please advise! Thank you!
In ASME, the leakage path of a pipe fitting refers specifically to: the shortest distance from the root of the pipe fitting weld to the surface (the minimum radius R, with point 1 at the root as the center) – minus the diameter of any pores present in the weld
This question is strange; does it make any sense? It would be better to use NDE to determine the defect level
An NDE can only determine whether there are defects such as pores and lack of weld penetration; it is not possible to detect the size of the leakage pathways. Measurement can only be carried out by cutting the specimen through simulation tests. Therefore, only welders who have passed the examination may be used.
