Classification and Function of Thick-walled Seamless Steel Pipe
Jun 25, 2018

In the production and processing of thick-walled seamless steel pipe products, different manufacturing processes can be used. Common four methods are cold drawing, cold rolling, hot rolling and thermal expansion. Generally thick-walled seamless steel Pipe are made of 10#, 20#, 35#, and 45# ordinary steel pipes, which are divided into structural seamless pipes according to the purpose; seamless steel pipes for transportation; seamless steel pipes for boilers; Seamless steel pipe and so on.


Combined with the current application situation, thick-walled seamless steel pipes include different uses. The stainless steel seamless pipe for the top pipe structure is a seamless steel pipe used for general structure and mechanical structure, and is widely used in corrosion-resistant pipes and structural parts and parts of chemical industry, petroleum, textile, medical, food, machinery and other industries. Hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel Pipe.


In addition, there are some thick-walled seamless steel Pipe, which are called special-shaped seamless steel Pipe due to the special shape structure, and refer to the general term of seamless steel Pipe of other cross-sectional shapes other than circular Pipe. Shaped thick-walled seamless steel Pipe are widely used in various structural parts, tools and mechanical parts. They have large bending and torsion resistance, which can greatly reduce the structural weight and save steel materials.
