Products Information

Carbon steel pipe is the raw material of round billet, embryos after processing cutting machine's growth degree is about 1 meters circular tube blank, and the conveyor belt to the furnace heating. The billet is fed into the furnace heating, the temperature is about 1200 degrees celsius. Fuel for hydrogen or acetylene. The furnace temperature control is the key problem. Round tube blank released after pressure punch through the air. Generally more common puncher tapered roller machine, this machine has high production efficiency, good product quality, perforation diameter enlargement, can wear a variety of steel. After perforation, round tube has been three roll cross rolling, rolling or extrusion. After pressing to agrees to drive off. Sizing machine through the high-speed rotation of the cone drill into steel embryo punching, forming steel. Pipe diameter by sizing machine drill diameter length to be determined. Steel pipe sizing, enters the cooling tower, water cooling pipe through, after cooling, will be straightening. Pipe by straightening sent by conveyor metal detection machines (or hydrostatic test) internal inspection. Steel pipe internal cracks, bubbles and other issues, will be detected. Steel pipe quality inspection also through strict hand selected. Steel pipe quality inspection, use spray paint on the number, size, production batch number etc.. And by crane into the warehouse.
