Re: [MW:25561] Hydrostatic leak testing

if not a sensitive test is not required you may go ahead. For sensitive leak test check 345.8.
However, is up to the Engineering to determine if a sensitive leak test is required.

Dear all

Vendor has offered piping spool for hydrostatic test after painting.

Code of construction is ASME B31.3. Category M fluid service.


Vendor argues that as per ASME B31.3 clause 345.3.1 all joints may be primed and painted prior to leak testing.

However same clause also mentions that all joints Welds shall be left exposed for examination during leak testing which is contradictory. 

Nothing is mentioned in hydro test procedure about painting.

How to accept ?
