BLACK WELDED CONCRETE LINED STEEL PIPE
Welding concrete lined pipe0183;32;Has anyone had any experience welding concrete lined pipe?. I had a call out Friday afternoon to weld a 8" water main that a rubber flange had let go on, I ended up welding two joints as the company's new practice it to weld not replace the rubber. The pipe was 8" in dia and 1/4thick with a 1/4 thick concrete lining. It had a fairly thick bitumen coating on it.
