What is Seam Pipe

Seam pipe refers to the strip or plate bending round, square and other shapes and then welded into the surface jointed pipe. Seam pipe is using a blank plate or strip.

With the advancement of high-quality steel rolling production as well as the rapid development of welding and inspection techniques, and continuously improve the quality of welds, pipe joints increasing varieties and specifications, and in more and more areas instead of seamless steel tubes. Seam pipe is lower than seamless steel pipe on cost, high production efficiency.

According to different welding methods can be divided arc welded pipe, high-frequency or low frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes.
Press seam shape classification can be divided into longitudinal and spiral welded pipe.
By end-use is divided into general welded pipe, galvanized pipe, oxygen blowing pipe, wire casing, metric pipe, roller tube, deep well pump tube, automotive tube, transformer tube, welding thin-walled tube, welding shaped tube and spiral welded pipe.
Press the end of the shape classification is divided into circular pipe and shaped (square, flat, etc.) pipe.
