Process : high-quality carbon steel billets are selected to ensure their excellent performance from raw materials; special machine tools are used for fine drawing or fine rolling, and the inner and outer walls of the steel pipe have high smoothness and dimensional accuracy, showing the characteristics of metal white and bright similar to stainless steel; vacuum protection bright heat treatment process, There is no oxide layer on the inner and outer walls of the precision seamless steel pipe; it fully meets the requirements of mechanical properties such as high pressure resistance, tensile strength, and impact resistance. The steel pipe has no cracks after bending and flaring, and has excellent performance; After flushing, the inner and outer walls of the steel pipe are coated with anti-rust oil for anti-rust treatment, and both ends are covered with dust-proof covers.
Application industry: used in automobile pipelines, hydraulic and pneumatic systems and users who have high requirements for steel pipe accuracy, inner and outer wall finish, high cleanliness and mechanical properties; fully meet the requirements for high-clean hydraulic pipelines, and the effect is ideal; in hydraulic cylinders , engine, hydraulic pump station, hydraulic system and other fields are widely used, and it is an ideal pipe for mechanical hydraulic devices.
