What is precision hydraulic seamless steel pipe? ——Refers to cold-drawn or cold-rolled precision seamless steel pipes with precise inner diameters for the manufacture of hydraulic and pneumatic cylinders.

Introduction of precision hydraulic seamless steel pipe process:

Precision hydraulic seamless steel pipes made of precision cold drawn seamless steel pipes that are processed by black or gray phosphating process, and the phosphated steel pipes are sealed and rust-proofed.

A dense phosphate layer is formed on the inner and outer surfaces of the steel pipe. After the anti-rust treatment, the steel pipe is effectively prevented from being oxidized. Therefore, the steel pipe has excellent anti-rust performance. At the same time, the microporous phosphate film (layer) formed after the steel pipe surface It can effectively absorb the paint on the surface of the steel pipe and effectively prevent the paint from falling off. It is an ideal product for use in a field operation environment.

When using this steel pipe, it is recommended that the user do cleaning after the steel pipe is bent, such as using a sponge to use compressed air for pass-through cleaning. Of course, the pre-cleaning of the system before the normal operation of the hydraulic system is also a necessary step.

The steel pipes used in the hydraulic system are mainly stainless steel seamless pipes and ordinary seamless steel pipes. Although stainless steel seamless pipes have superior mechanical properties, they have not been widely used due to their high prices and low precision. Although ordinary seamless steel pipes are commonly used, they have poor mechanical properties and low precision. They usually go through a series of welding, trial assembly, pickling, alkali washing, water washing, long-term oil stringing, leak testing, and procedures before use. Complexity, time-consuming, unreliable materials, and the inability to completely remove the residues in the pipe have become a major hidden danger for the entire hydraulic system to fail at any time. According to statistics, 70% of the failures in the hydraulic system are caused by this reason.
