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
