Production Method Of Steel Tube

Steel pipes are divided into seamless steel pipes and welded steel pipes. The seamless pipe production process is to thread solid billets or ingots into hollow capillaries, which are then rolled into the required size tubes. The different perforation and rolling methods used constitute different methods for the production of seamless steel pipes. The welded steel pipe production process is to bend the pipe blank (steel plate or strip) into a tube, and then weld the gap to become a steel pipe. Due to the different forming and welding methods used, it constitutes different methods for the production of welded steel pipes.

Seamless steel pipes are mainly produced by the hot rolling method. The extrusion method is mainly used to produce low-plastic, high-alloy steel pipes or special-shaped steel pipes and composite metal pipes that are difficult to perforate. The cold rolling and cold drawing method can continuously process the hot rolled pipe into small diameter and thin wall steel pipe. The welded steel pipe has a simple process, high production efficiency, low cost, and an increasingly expanding product variety.
