Hi,
The Contractor is right,Normally Pneumatic test will be done of Re-Inforcement Pad of Nozzles only.In your case this is just a pad plate to avoid shell material directly welded to another kind of material.No need to do Pneumatic test on this.
Thanks & Regards,

Dear members,
Gas Discharge Volume Bottle (508 O.DX2083 LG) Reinforcement pad -2 nos are missing which is used for sitting the vessel on the roller support
This pad is located in between Vessel & roller Support.
Fluid service: Gas
The Pad Re-Installation will be rectified at site.
Contractor says that there is NO POST WELD HEAT TREATMENT for this vessel also this is a saddle pad and doesn't require pneumatic test of pad which is acceptable or not.
Pls. clarify this issue.Thanks & Regards,Praveen Kumar--
