Product Description
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.
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.
Cold drawing (rolling) carbon steel seamless steel tube: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage.
Carbon steel seamless steel pipe because of its different manufacturing process, and divided into hot rolled (extruded) seamless steel pipe and cold drawn (rolled) seamless steel pipe two. Cold-drawn (rolled) pipe is divided into circular pipe and special-shaped pipe two kinds.
