The raw material of carbon steel pipe is round pipe billet. The round pipe billet is cut by the cutting machine and processed into the billet with the length of 1 meter. And then sent to th furnace tobe heated by the conveyer belt. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a key issue. After the round tube billet to go through the pressure piercing machine to wear empty. Generally more common punching machine is conical roller piercing machine, this punching machine production efficiency is high, product quality is good, perforation expansion diameter large, can wear a variety of steel. After piercing, the round tube blank has been three-roll cross-rolling, rolling or extrusion. Squeeze after the tube diameter. Sizing machine through the high-speed rotation of the cone drill bit into the steel embryo drilling, the formation of steel pipe. The inner diameter of the pipe is determined by the outside diameter of the sizing bit. Steel pipe after sizing, into the cooling tower, through the water cooling, the cooling pipe, it is necessary to be straightened. After straightening by the steel pipe sent to the metal detector (or water pressure test) for internal testing. If the pipe has cracks, bubbles and other problems, will be detected. After the quality of steel pipe but also through rigorous manual selection. After the quality inspection of steel pipe, spray paint with the number, size, production lot number. And suspended by the crane into the warehouse.
