The production of 304 stainless steel pipes is very strict. A slight discrepancy will result in the scrapping of the finished product. 304 stainless steel pipe is a precision cold drawn seamless steel pipe that has been phosphated in black or gray. The phosphated steel pipe is sealed, and the precision hydraulic seamless steel pipe has been anti-rust treated.

A dense phosphate layer is formed 304 the inner and outer surface layers of the stainless steel tube. After anti-rust treatment, it can effectively prevent the steel pipe from oxidizing, so the rust resistance of the steel pipe is very good. At the same time, because the surface of the steel pipe is phosphated to form a microporous phosphate film (layer), the coating can be firmly attached to the surface of the steel pipe, effectively preventing the coating from falling off. It is the ideal product for field operation.

UseWhen 304 stainless steel pipes, it is recommended that users scrub the pipes after bending them, such as scrubbing with a sponge and compressed air. Of course, pre-cleaning the system before the normal operation of the hydraulic system is also a necessary step.

The steel pipes used in the hydraulic system are mainly304 stainless steel pipe and ordinary seamless steel pipe. Although 304 stainless steel pipes have excellent mechanical properties, they are not widely used due to their high price and low precision. Although ordinary seamless steel pipes are widely used, they have poor mechanical properties and low accuracy. Before use, they are usually subjected to a series of welding, trial assembly, acid washing, alkali washing, water washing, long-term oil discharge and leak testing. This process is more complicated. The time-consuming and expensive materials are unreliable, and the residues in the pipes have not been completely removed, which becomes the main problem that the entire hydraulic system fails at any time. According to statistics, 70% of hydraulic system failures are caused by this reason.

304 stainless steel pipe is made of various special-shaped seamless steel pipe by cold drawing. It is usually distinguished according to the section, and can be divided into seamless steel pipe, aluminum alloy pipe and plastic pipe according to the material. 304 stainless steel pipe anti-corrosion treatment methods are:

1、InCoat 304 stainless steel pipe with asphalt paint;

2、Special coating for cement mortar lining;

3、Coated with epoxy coal tar pitch304 stainless steel pipe;

4、Epoxy ceramic lining;

5,Aluminate cement coatings and sulphate cement coatings;

6,In304 stainless steel tube coated with polyurethane.
