First, the principle of seamless steel pipe extrusion
Seamless steel pipe extrusion is a processing technology that extrudes the tube into shape through instantaneous deformation inside the tube. This process is implemented in two ways: cold extrusion and hot extrusion, of which hot extrusion is the more widely used method. Hot extrusion is a process in which the steel tube billet is heated to a higher temperature, gradually cooled by continuous multi-stage extrusion, and finally formed in the mold. This extrusion method can produce seamless steel pipes with higher strength, better corrosion resistance, and better surface quality.

Second, the application of seamless steel pipe extrusion
Seamless steel pipe extrusion is widely used in automobile manufacturing, the petrochemical industry, machinery manufacturing, high-pressure boilers, and other fields. In automobile manufacturing, seamless steel pipe extrusion is used to manufacture automobile bearings, shock absorber sleeves, engine cylinders, and other parts. In the petrochemical industry, seamless steel pipe extrusion can be used to manufacture high-pressure pipelines such as chemical pipelines and oil pipelines. In machinery manufacturing, seamless steel pipe extrusion is used to manufacture machine tools, ships, compressors, hydraulic cylinders, and other mechanical manufacturing equipment. In high-pressure boilers, seamless steel pipe extrusion can be used to manufacture steam drums, heaters, supercritical boilers, and other parts.

In short, seamless steel pipe extrusion is a very important processing technology with a wide range of applications, which can provide high-quality materials and components for different industries.
