Precision hydraulic seamless pipe is a precision hydraulic seamless steel pipe made of precision cold drawn seamless tubing treated with black or gray phosphating process, and the phosphating steel pipe is sealed and rust-proof.
Note: Cold-drawn precision seamless steel pipe is a high-precision steel pipe material. The main categories are: precision seamless steel pipe, precision hydraulic seamless steel pipe, cold-drawn precision seamless steel pipe, cold-rolled precision seamless steel pipe, high-precision seamless steel pipe, precision bright seamless steel pipe. The main features are that there is no oxide layer on the inner and outer walls of the steel pipe, no leakage under high pressure, high precision, high finish, no deformation after cold bending, no cracks in flaring and flattening. Therefore, it is mainly used in hydraulic system piping, automobile manufacturing piping, military industry, construction machinery, railway locomotives, aerospace, ships, injection molding machines, die-casting machines, machine tools, diesel engines, petrochemicals, power stations, boiler equipment and other industries.
A dense phosphating layer is formed on the inner and outer surfaces of the precision hydraulic steel pipe, and after the anti-rust treatment, the oxidation of the steel pipe is effectively prevented, so the anti-rust performance of the steel pipe is excellent.At the same time, due to the microporous phosphating film (layer) formed on the surface of the steel pipe, it can strongly adsorb 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 field operations.
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 good performance, they are expensive and low in precision, so they have not been widely used. Although ordinary seamless steel pipes are widely used, they have poor mechanical properties and low precision. Before use, they usually go through a series of complicated processes, which are time-consuming and expensive.And it has not been able to completely remove the residue in the pipe, which has become a major hidden danger for the entire hydraulic system to fail at any time.
The complex process of using ordinary seamless steel pipes in the hydraulic system has become a high-investment and high-cost work, which greatly increases the cost of enterprises.
Comparison of Precision Hydraulic Seamless Pipe and Ordinary Seamless Pipe
1. Precision hydraulic seamless pipe
①There is no oxide layer on the inner and outer walls, which can be directly installed in the hydraulic system for use
② withstand high pressure without leakage
③High precision
④High finish
⑤ Cold bending does not deform
⑥Flaring, flattening without cracks
2. Ordinary seamless steel pipe:
①Welding: produce welding slag, oxide layer, and possible leakage
②Pickling: consumables, time-consuming, labor-intensive and dangerous
③Alkaline cleaning: consumables, time-consuming and labor-consuming
④ Washing: waste of resources
⑤ Long-term oil consumption: power consumption, oil consumption, time-consuming and labor-consuming
⑥Leak test: to repair welding
