Precision Sealess Hydraulic Steel Tubes Features
Precision Seamless Steel Tubes Details
Galvanized Steel Tubes
Zinc forms a protective film with metallic luster on the surface of the pipe, isolating oxygen and moisture. The seamless carbon steel hydraulic tubes is galvanized to improve corrosion resistance, wear resistance and extend service life.
Phosphated Steel Tubes
Phosphating is the process of forming a phosphate film on the surface of steel tubes. Phosphating allows subsequent coatings (such as paint, coatings or anti-corrosion coatings) to adhere better to the surface of hydraulic steel pipes, thereby enhancing the adhesion of the coating and improving the surface protection effect. It can also improve corrosion resistance.
Tube Assembly
Seamless carbon steel hydraulic pipes are bent and screwed into fixed components, which are widely used in hydraulic and pneumatic systems. Screwed components are mainly used for connecting and fixing hydraulic tubes, usually including accessories such as bolts, nuts, joints or pipe adapters. These components ensure a firm and stable connection between tubes and equipment.
