High-precision black phosphated precision hydraulic steel pipe
Introduction to the process of high-precision black phosphated precision hydraulic steel pipe: high-quality carbon steel, fine drawing, non-oxidation bright heat treatment (B state), non-destructive testing, the inner wall of the steel pipe is specially designed The equipment is scrubbed and washed with high pressure, anti-rust oil is applied to the steel pipe for anti-rust treatment, and both ends are capped for dust-proof treatment.
The main features of high-precision black phosphated precision hydraulic steel pipes: high precision, good smoothness, no oxide layer on the inner and outer walls of the steel pipe after heat treatment, good inner wall cleanliness, the steel pipe can withstand high pressure, no deformation during cold bending, no expansion or flattening Cracks can be subjected to various complex deformations and mechanical processing. Steel pipe color: light gray with white.
The main uses of high-precision black phosphated precision hydraulic steel pipes: steel pipes for hydraulic systems, steel pipes for automobiles, and other customers who have high requirements for steel pipe accuracy, smoothness, cleanliness, and mechanical properties. It is especially suitable for hydraulic precision injection molding machines. Seamless steel pipes, hydraulic precision seamless steel pipes for die-casting machines, precision hydraulic seamless steel pipes for silicone machinery, precision hydraulic seamless steel pipes for rubber machinery, precision hydraulic seamless steel pipes for plastic machinery, precision hydraulic seamless steel pipes for vulcanizing machines, molded High-precision black phosphated steel pipe for machine use,
