Processing method of stainless steel pipe fittings
Stainless steel pipe fittings are a new type of pipe fittings that are widely used. Generally speaking, the processing methods are as follows : 1. Forging method: the end or part of the pipe is punched out with a swaging machine to reduce the outer diameter. Common swaging machines include rotary...Read more -
Stainless steel does not rust
Stainless steel is an extremely thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on its surface to prevent the relay of oxygen atoms. Continue to penetrate, continue to oxidize, and obtain the ability to resist rust. Once for some reason, this kind of film has bee...Read more -

What causes corrosion of stainless steel welded pipe?
There are two main reasons for corrosion of stainless steel welded pipe 70% are processed. Due to the contamination of iron and copper tools during processing, the argon gas in the welding cannot be well protected and oxidation will occur. In addition, excessive damage to the surface of the anti...Read more -
The difference between precision steel pipe and spiral steel pipe
Precision spiral steel pipe is a high-precision steel pipe that is cold drawn or hot rolled. Because the inner and outer walls of the precision spiral steel pipe have no oxide layer, there is no high pressure, no leakage, high precision, high smoothness, no cold deformation, flaring, flattening, ...Read more -
