Popular Design for Cold Drawn Seamless Pipe - Heavy Wall Steel Pipe – XUANZE Detail:

The production and manufacturing process of heavy wall seamless steel pipe can be divided into cold drawing, cold rolling, hot rolling and hot expansion. The materials of steel pipe are 10, 20, 35 and 45, which are called ordinary steel pipe. According to the application, it can be divided into structural seamless steel pipe, seamless steel pipe for transportation, seamless steel pipe for boiler, high-pressure seamless steel pipe for boiler, high-pressure seamless steel pipe for chemical fertilizer equipment and seamless steel for geological drilling Pipe; seamless steel pipe for oil drilling; seamless steel pipe for petroleum cracking; seamless steel pipe for ship; cold drawn and cold-rolled precision seamless steel pipe; various alloy pipes. Seamless steel pipe is mainly used in mechanical processing, coal mine, hydraulic steel, etc.

The raw material of thick wall seamless steel pipe is round tube blank. The round tube blank is cut by cutting machine, and the billet with a growth of about 1 m is sent to the furnace by conveyor belt for heating. The billet is heated in a furnace at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. After the round tube is discharged from the furnace, it needs to pass through the pressure piercer. Generally, the more common piercer is the cone roll piercer. This kind of piercer has high production efficiency, good product quality, large perforation diameter expansion, and can wear a variety of steel grades. After piercing, the round billet is successively rolled by three roll cross rolling, continuous rolling or extrusion. After extrusion, the tube should be removed for sizing. The sizing machine rotates the cone drill bit into the steel blank at high speed to form a steel pipe.

The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe enters the cooling tower and is cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by conveyor belt for internal flaw detection. If there are cracks and bubbles inside the steel pipe, it will be detected. After the quality inspection of steel pipes, strict manual selection is required. After the quality inspection of the steel pipe, the number, specification and production batch number shall be sprayed with paint. It is hoisted into the warehouse by crane.
