316 316L Round Welded Seamless Stainless Steel Pipe
How to correct 316l stainless steel pipe?
This is related to the wall thickness, the other is seamless pipe or welded pipe, if it is seamless pipe when you weld, please lower your welding machine gear, if you do not need to expand the product after forming, please connect to its heat treatment process, is water-cooled or oil-cooled, or natural cold, this has a very subtle relationship, itself 316L and 304 heat treatment methods are different, Really want to non-destructive roundness after welding, in addition to your technical requirements, only re-solid melting. Then pickling.
