[MW:8633] Requirement of RT as per ASME Sec. VIII

Dear All,

 

My question is about requirement of RT for butt-weld joints as per ASME Sec VIII. We have ask vendor to manufacture ASME CL 150 Bucket type strainers as per ASME B31.3 and ASME BPVC Sec.VIII, but we didn't mention any weld joint testing requirements in our requisition and neither it was discussed before issuance of PO. However we have asked for hydro test.

 

Now I want to ask is there any mandatory requirement of ASME Sec VIII to perform RT on all butt-weld joints of bucket type strainers because vendor is manufacturing strainer from PIPE API 5L - B.

Because we have asked vendor to perform 100% RT on all butt weld joint and vendor is asking for addition cost to perform RT. 

 

Please advise or tell me para of ASME Sec VIII, or other applicable NDE requirements as per ASME.

 

Regards.
