Stainless steel pipe is a long strip of steel with hollow section and no joints around it. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher its processing cost will be.

Manufacturing process hot rolling (seamless steel pipe): round tube blank → Heating → Perforation & rarr; Three roll cross rolling, continuous rolling or → Off pipe & rarr; Sizing (or reducing) → Cooling → Straightening & rarr; Hydrostatic test (or flaw detection) → Mark & rarr; The raw material for warehousing and rolling seamless pipe is round pipe blank. The round pipe blank shall be cut and processed by cutting machine, and the blank with a growth of about 1m shall be brought to the furnace for heating. The billet is sent to the furnace for heating at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature in the furnace is the key problem. After the round tube billet is discharged from the furnace, it should be pierced through the pressure piercer. Generally, the more common piercer is the cone roll piercer. This piercer has high production efficiency and good product quality. It is specialized in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe, with high pressure resistance grade, good waterproof performance, fire and high temperature resistance, strong overload capacity,High temperature stainless steel strip, corrosion resistance, radiation protection, long service life, large perforation diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively rolled by three roll cross rolling, continuous rolling or rolling. Take off the pipe after sizing. The conical drill bit of the sizing machine rotates into the steel embryo at high speed to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower for water spray cooling. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydrostatic test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, they will be detected. Steel pipes should be strictly selected manually after quality inspection. After the steel pipe is inspected, the number, specification, production batch number, etc. shall be sprayed with paint. And hoisted into the warehouse by crane.
