Cold drawn seamless steel pipe feature
Carbon seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. The most advantage is increasing the ability of withstanding higher pressure.n improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe.
Widely used for liquid, gas, and steam services both above- and below ground services.

Cold drawn seamless steel pipe is a kind of highly detailed seamless steel pipe after cold rolling or cold drawing; full name: cold drawn seamless pipe. Due to the advantages of no air oxide layer on the inner and outer walls of the cold drawn seamless pipe, no leakage under high pressure, high precision, high smoothness, no deformation in cold drawing, flaring, flattening without gaps, etc., it is mainly used for the production of pneumatic or Commodities of hydraulic parts, such as cylinders or hydraulic cylinders, are all made of seamless steel pipes.
The components of cold drawn seamless steel pipe are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr. The method to balance supply and demand at the structural level is relatively limited. It should be emphasized that when listening to the methods described in the opinions, other problems usually arise. At this time, the main differences should be grasped and the main problems should be solved. method to solve.
Cold drawn seamless steel pipe has the advantages of high precision and smoothness, no air oxide layer on the inner and outer walls, can accept high pressure, no deformation after cold drawing, flaring, flattening without gaps, etc. The round steel pipe of cold drawn seamless pipe is mainly used for For the production of pneumatic or hydraulic parts, such as seamless steel pipes for cars, crude oil drilling tools, etc. The special-shaped pipe in cold drawn seamless pipe can be widely used for various parts, articles and mechanical parts.
