Black Phosphated Cold Drawn Seamless Tube

• 1. what is a black phosphated hydraulic steel tube?

DIN series high-precision fine-drawn bright seamless steel pipe is used as the finished phosphating strip steel pipe, and the outer wall of the steel pipe is phosphating with imported environmental protection phosphating solution.

• 2.Advantages of black phosphated hydraulic steel tube

The black belt is bright and the color steel surface is smooth.
Strong consistency and better appearance.
Good anti-rust performance of pipe.
Clarinet phosphides are mainly used in hydraulic systems.

 

 

High-precision precision hydraulic steel pipe is a special pipe for hydraulic systems, which has obvious advantages. There is no oxide layer on the inner and outer walls of the steel pipe. It can be installed directly in the hydraulic system and can withstand high pressure without leakage. No deformation, flaring, flattening without cracks.

So what will happen to the high-precision precision hydraulic steel pipe after the black phosphating process?

The high-precision precision hydraulic steel pipe is treated with black or gray phosphating process, and a dense phosphating layer is formed on the inner and outer surfaces of the steel pipe, and the steel pipe has excellent anti-rust performance. High-precision EN/DIN black phosphating hydraulic pipe produced by steel pipe, the inner and outer walls of the steel pipe are phosphating with imported environmentally friendly phosphating solution. After surface phosphating, a black phosphating protective film is formed. The micropores in the phosphating film absorb anti-rust oil for anti-rust treatment. The surface of the steel pipe can effectively prevent the paint from falling off, and the ends are re-sealed for dust-proof treatment.
