I didn't take time earlier to write down what spec, if any, was stamped on the pipe. It was made by Alaskan Copper. Many of the sticks were two-seamed but I did notice one that had 3 seams.
I'll get more info on it tomorrow.
I've been researching this and found in ASTM-A312/A312M "STANDARD SPECIFICATION FOR SEAMLESS, WELDED, AND HEAVILY COLD WORKED AUSTENITIC STAINLESS STEEL PIPES" the following statement:
Welded pipe and HCW pipe of NPS 14 and smaller
shall have a single longitudinal weld. Welded pipe and HCW
pipe...
Does ASME piping code allow welded seam pipe to have multiple seams? Specifically I'm curious about 24" 10s 304-L SS pipe. If multiple seams are allowed, is there a limit? Anyone seem pipe come in with 2 and 3 weld seams? I'm referring to longitudinal seams, not circumfrential.
thanks.
