Dear Mr. Carlos,

Could you please mention the corresponding clause as per ASME B31.3 which insist fabricator to keep minimum distance(offset) between two long seams for better understanding?

Regards,

Limesh

What is your material...?

If the material is not susceptible to stress relief (like many stainless steels), you can submit a TQ and suggest to carry out stress relief for both parts and then proceed to weld...

Dear Friends,

Got a case where 2 nos 45 degree elbows are to be welded together and both long seams are coinciding without any staggering.

There is no provision for welding a pipe piece due to space restriction.

Code is ASME/ANSI B31.3

Size is 28" dia x 60 mm thick.

Joint will be covered by PWHT and NDT is Phased array UT before and after PWHT.

Can we do this as per code?

If yes with what clause/section etc.

Please share your opinions.

Thanks in advance for your help.

Best Regards

T.V.Ramakrishna.
