Longitudinal weld seams of adjoining sections (AWS D.1.1 Cl. 5.22.3)
(OP)
Gents,
Can someone spare their precious time in giving a solution to my below question please?
1. As per AWS D1.1 Cl. 5.22.3.1 Longitudinal weld seams of adjoining sections shall be staggered a minimum of 90°. We have a typical problem at site in which we have only 40-50°. How to resolve the issue?
2. Two 45° Elbows were welded together to get a 90° Elbow. The Elbows are 30" butt welded type as per B16.9. Now the existing welds on the 45° elbows are meeting at same location. There is no reference in B31.3 on this scenario. How to resolve? I am attaching a sketch also with this.
Thanks in advance.

This jacket is already piled in sea and a 3800 ton production station is now resting on that.
This one is designed in acc. to AWS D1.1. It is not a process piping to design in Acc. to B31.3

Since, after a long series of questions and answers, we find that your problem is a structural problem, not a process piping problem.....
I believe that you should post your question in one of the structural engineering forums, not the "piping & fluid mechanics forum"
