RE: [MW:0] VESSEL Reinforcement pad Installation

If the vessel is to be PWHted  due its service, then along with Pads it gets PWHT ed.

Otherwise, just for attaching the pads , that too non pressure retaining purpose, there is no requirement to do PWHT.

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
