Seamless steel pipe and seamless steel pipe differences there are several common market, welded pipe, spiral welded and seamless steel pipe, welded pipe and spiral welded pipe but are very good identification, seamless pipe and Seamless Steel difference. From several perspectives: First, in general are welded steel pipe length of the bread, and are generally 6 meters, nine meters or 12 meters. Seamless steel pipe length is very small, because the factory length increases very much. The second from a cross-section of the ferrule to see if there is rust, then put him clean hexagonal pipe, if you look carefully will find the weld area. Third, if the pickling it, then the most obvious.
