Introduction of electric fusion welding process

Electric fusion welding process is an efficient, energy-saving, and environmentally friendly steel pipe production technology. EFW steel pipes are melted at both ends of the steel plate by electric heating, and then tightly bonded at both ends by welding rollers to form seamless steel pipes. The characteristics of efw steel pipes are high production efficiency, low cost and no internal stress. It is widely used for transporting of oil and gas.
