I would like to ask the experts: In standards such as ASME B31.3, are there any specific requirements regarding the offset of longitudinal welds when performing butt welding on large-sized straight-seam pipes? What is the required offset distance for longitudinal welds according to these American standards?

There should be a separation of at least 200; generally, it is required that the separation be at an angle of 45 degrees above, so that the bracket does not cover the pipe welds

In actual projects, the inspection party has requested that the same approach as used on the third floor be adopted in order to avoid overlapping welds on the welding bracket gussets
