Three production processes of welded pipe
Steel pipe is generally divided into seamless steel pipe and welded steel pipe according to production methods. This time we mainly introduce welded steel pipe,that is,welded steel pipe.Its production is to bend the tube blank (steel plate and steel strip into the required cross-section shape and...Read more -

Deformation strengthening of high-pressure alloy pipe
High-pressure alloy pipe deformation strengthening is using the method of deformation of steel reinforcement. Also known as the strain hardening or work hardening. The strength of the material at the macro (or a whole) the ability to resist deformation (or flow stress). Hardness is the ability of...Read more -
What is the difference between seamless steel pipe and seamed steel pipe
(1) seamless steel pipe is generally rolled from carbon steel or low-alloy structural steel, is the earliest application of steel pipe material, its cross-sectional area is larger, the unit area under pressure is smaller. (2) Seamed steel pipes are mainly used to transport fluids. Due to the manu...Read more -
Classification of seamless steel pipes
Seamless steel pipe has a hollow cross-section and is used in large quantities as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Steel pipe and round steel and other solid steel, compared to the same bending and tor...Read more -
