i have a company wishing to perform Pipeline Inline Inspection (ILI) utilizing Mechanical Feeler Defect Sensing (MFDS) to replace hydrotest requirement. Is inline inspection to detect defects as good as hydrotest?

By the way, what is MFDS?, I googled this having never come across the term before and it didn't come up.

brimmer, when was that provision adopted? Has it always been the case, or is it relatively recent?

On the other hand, there have also been many, and sometimes quite inventive or imaginative arguments with rather convincing local justification or rationalizations, to avoid hydrostatic testing. I guess I’ve seen a problem or two in the now near forty years I’ve been around the pipeline business where it was confirmed that for whatever reasons properly run hydrostatic testing was not done, and problems were later discovered in/from the pipelines.

Until B31.4/8 change, I guess we can take advantage of the big experimentation area north of the border.
