Mechanical property

Product specification:

Outer diameter of hot-rolled pipe is 32~630mm. The wall thickness is
2.5~75mm. The outer diameter of cold rolled (cold drawn) pipe is
5~200mm. The wall thickness is 2.5~12mm.
Appearance quality: the internal and external surfaces of steel pipes shall be free of cracks, folds, folds, delamination, hairlines and scabs. These defects shall be completely removed, and the wall thickness and outer diameter shall not exceed the negative deviation after removal.
Both ends of the steel pipe shall be cut at right angles and the burrs shall be removed. Gas cutting and hot saw cutting are allowed for steel pipes with wall thickness greater than 20mm. 

Product characteristics

High precision: The inner and outer diameter of the precision tube can be accurate to within 0.2mm, which makes it has important application value in the manufacture of various precision mechanical parts and engineering structures. High finish: no oxide layer on the inner and outer walls of the precision tube, excellent surface quality, can withstand high pressure without leakage, suitable for high pressure and high precision requirements. Mechanical properties: While ensuring flexural and torsional strength, the precision tube also has a light weight, which makes it more flexible and economical in structural design.

 

Production technology:

The production of precision pipe mainly adopts cold drawing or cold rolling process. This process can significantly improve the precision and surface quality of the steel pipe, while maintaining the mechanical properties of the steel pipe. In the production process, it is also necessary to carry out heat treatment, non-destructive testing and other processes to ensure product quality.

product application

^{Seamless pipes are widely used. Seamless pipes for general purposes are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for conveying fluid.
Supply is divided into three types according to different purposes: a. Supply according to chemical composition and mechanical properties; B. Supply according to mechanical properties; C. Supply according to hydraulic test. The steel pipes supplied according to category a and b shall also be subjected to hydraulic test if they are used to bear liquid pressure.
There are many kinds of seamless pipes for special purposes, such as boiler seamless pipes, geological seamless pipes and petroleum seamless pipes.}
