Seamless Carbon Steel Pipe (Seamless carbonsteel pipe) is made of steel ingot or solid tube blank through perforation to make capillary, and then hot-rolled, cold-rolled or cold-drawn. The raw material of seamless carbon Steel Pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls. After extrusion, the tube should be removed and sizing. The sizing machine rotates into the steel billet at high speed through the conical drill bit to punch holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter of the drill bit of the sizing machine. Hot-rolled Seamless Steel Pipes are divided into general steel pipes, low and medium pressure Boiler Steel Pipes, high pressure boiler steel pipes, alloy steel pipes, Stainless Steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
