Hi All,
I am working on modification of SS 316L atmospheric tank. The design internal pressure is 10 psi, design external pressure is 2 psi and design temp is 250 deg F.
As per the drawing the vessel is manufactured as per ASME Code section VIII Div 1 but it is not inspected and stamped.
My problem is I have to locate the nozzle and at the most preferred location there is weld seam of shell. The nozzle is a 6" pipe which will be welded to make tangential entry of liquid.
My question is can we weld on weld seam if not then what is the minimum distance another welding should start from one weld?
What are the problems of welding on weld seam.
Please let me know if you need any other information.
Thanks in advance.
