Re: Re: [MW:29346] S275JR

Depending upon your service condtion, thickness requirement and as metioned below chemistry / mechanical properties should compare with ASME listings of what you have and in any case it got merged then you do not need to fuse a PQR, but in many case it dont, scrutize with what you have VS ASME listings.

Thanks.

A36 is almost equal to s275 jr, but no proof if documents except Aramco procedure.

If you need to follow sec ix, need new PQR.  s275jr cannot categorise in ASME sec ix.

S275JR material is not listed in ASME Section IX and it is superior that S235JR.

Hence you have to go for new PQR.

Gents,

I have some queries on Subject material ,What is equivalent to S275JR as per SEC IX ?

If it is un assigned material , We can weld WPS qualified already in S235JR to A-106 Grade B or we have to qualify new WPS ?

Regards,

Saravanan
