Stainless Steel Seamless Pipe

Stainless steel seamless pipe is a pipe product made of stainless steel material. Its main feature is that the inner and outer surfaces of the pipe are smooth, there is no obvious welding interface, and the whole presents a seamless structure. Stainless steel seamless pipe is usually made of stainless steel plate through hot rolling or cold drawing and other production processes and has high corrosion resistance and high-temperature resistance.

Stainless steel seamless pipe is widely used in petrochemical, chemical, pharmaceutical, food processing, aerospace, and other fields, for conveying various media such as liquids, gases, chemicals, etc. Under special conditions such as high temperature, high pressure, pollution-free, and corrosion resistance, stainless steel seamless pipe is an ideal choice of pipe material.

 Cold Drawn Technology Cold Drawing Process

In the cold drawing process a hot finished seamless tube is used as the material (mother tube), the mother tube, after pretreatment, is cold drawn by the drawing bench to specified dimensions, as shown in the following diagram. the processed tube is subjected to final heat treatment based on its intended end use and then sent to the finishing and inspection process.

Hot Drawn Technology

The seamless pipe product is finally formed by heating the metal billet to a certain temperature (usually above 1200 degrees Celsius), and then using special equipment to pass the billet through multiple roll rolling, perforation, and other processes, and pressing the heated metal billet into a tube.
