Speaking of welded pipe, I believe that many people have a lot of mistakes, some understanding is to weld the pipe together, some welding into the pipe, actually understand is not wrong, but generally speaking for welded pipe enterprises, is to use welded pipe machinery to produce a pipe, it is called welded pipe.

Generally, welded pipes are divided into spiral welded pipes and straight welded pipes in a conventional manner. The selection of pipe welding machinery is also different, and the production process is naturally different. The surface is welded to get a pipe, but the welding path is actually different. The spiral pipe is mechanically wound by twisting the coil and welding it through submerged arc welding or other means where the coil is connected. The pipe appears to be wound out. Straight seam pipe welding machinery is to coil the steel coil, the two ends of the steel coil butt welding, get a pipe, the weld of this pipe is basically in a straight line, so it is called straight seam welding.
