BOLTS USED DURING HYDROTEST
BOLTS USED DURING HYDROTEST
(OP)
We have to hydrotest some vessels as per ASME VIII div.1 Code prior to "U" stamp them, but PTFE coated bolts required by Specification have not been delivered yet.
The question is: can we use other in-stock bolts suitable for the same pressure requirements, but not PTFE coated, to perform the hydrotest?
I cannot find any Code requirement for the chioce of bolting during hydrotest.
Thank you very much for support.

RE: BOLTS USED DURING HYDROTEST
Yes. The use of hardware and procedure to support a Code hydrostatic test is up to the organization taking responsibility for the hydro test, and concurrence from the AI.
