Seamless steel pipe and seamless pipe distinction there are several common market, longitudinally welded pipes, spiral welded pipe and seamless pipe, but the Longitudinal and spiral welded pipe are very good identification, seamless pipe and no the difference of the pipe joints. From several aspects: First, the pipe is cut to length in general, 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 can be seen from the cross section of the tube head of the T-shaped tube, if there is rust, then put him clean, look closely, you will find the weld zone. Third, if the pickling it, then the most obvious.
