The square rectangular steel tube forming machine factory believes that the steel pipe is used for conveying fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, and is also an economical steel.

　　square rectangular steel tube forming machine factory is divided by production method

　　Steel pipes can be divided into two categories according to the production method: seamless steel pipes and seamed steel pipes, and seamed steel pipes are referred to as straight steel pipes.

　　1. According to the production method, seamless steel pipes can be divided into: hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, hot-expanded pipes, cold-spinned pipes and extruded pipes, etc. Seamless steel pipes are made of high-quality carbon steel or alloy steel, and are divided into hot-rolled and cold-rolled (drawn).

　　2. The welded steel pipes of the square rectangular steel tube forming machine factory are divided into furnace welded pipes, electric welding (resistance welding) pipes and automatic arc welded pipes because of their different welding processes. Its end shape is divided into round welded pipe and special-shaped (square, flat, etc.) welded pipe.

　　square rectangular steel tube forming machine factory welded steel pipe is made of coiled steel plate by butt seam or spiral seam welding. , Welded pipes, etc. square rectangular steel tube forming machine factory seamless steel pipe can be used for liquid pneumatic pipeline and gas pipeline in various industries. Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.
