Carbon steel pipe can be divided into seamless steel pipe, straight seam steel pipe, spiral steel pipe, high frequency welded steel pipe and so on. The raw material for rolling seamless carbon steel tube is round tube billet. Round tube embryo is cut and processed by cutting machine and the billet with a growth degree of about 1 meter, and is sent to the furnace for heating by conveyor belt. The billet is fed into a furnace to be heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in furnace is the key problem. After the round tube billet comes out of the oven, it must go through the pressure punch. The most common puncher is the cone roll puncher, which has high production efficiency, good product quality, large diameter expansion and can wear a variety of steel. After perforation, the round tube is successively rolled by three rolls, cross - rolled, or extruded. After extrusion, take off the pipe and size. The sizing machine rotates into the steel embryo through the conical drill bit at high speed to drill and form the steel tube. The inner diameter of steel pipe is determined by the outer diameter length of drill bit of sizing machine. After sizing, the steel pipe enters the cooling tower and is cooled by spraying water. After cooling, the steel pipe is straightened. After straightening, the steel tube is sent by conveyor belt to metal flaw detector (or water pressure test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. Steel pipe quality inspection through strict manual selection.
