Stainless steel welded pipe vs carbon steel welded pipe
Stainless steel welded pipes are produced by curling and welding stainless steel plates or strips using specialized machinery and dies. A key component in stainless steel is chromium—typically more than 10.5%. For instance, 304 stainless steel contains about 18–20% chromium and 8–10.5% nickel, along with other alloying elements that enhance performance. Carbon steel welded pipes, in contrast, are made primarily of iron and carbon, with carbon content generally below 2.11%. They may also contain trace elements like silicon, manganese, sulfur, and phosphorus.

Backing welding methods of argon arc welding stainless steel pipes
The welding of stainless steel pipes typically involves three stages: root (backing) welding, fill welding, and cap welding. Among these, backing welding is the most critical step, as it directly influences both weld quality and construction progress. Currently, two primary backing welding approaches are used: argon-protected root welding and non-argon root welding. Each includes various sub-methods with distinct technical characteristics and field suitability. This article will briefly introduce backing welding methods of argon arc welding stainless steel pipes.

Advantages and disadvantages of galvanized ERW pipe
Galvanized ERW (Electric Resistance Welded) pipe is a high-frequency straight seam welded steel pipe that has been coated with a protective zinc layer through a galvanizing process. This zinc coating forms a dense barrier on the surface of the pipe, effectively isolating it from air and moisture. As a result, galvanized ERW pipes exhibit significantly enhanced corrosion resistance and a service life several times longer than that of standard ERW pipes. This article will briefly introduce advantages and disadvantages of galvanized ERW pipe.

Will 304 stainless steel welded pipe rust?
In addition to iron, 304 stainless steel welded pipes contain alloying elements such as chromium, nickel, aluminum, and silicon. Among them, chromium plays a critical role, with content typically not less than 12% and often reaching 18%. The addition of chromium enhances the uniformity of the steel's molecular structure and promotes the formation of a dense, stable oxide film on the surface, significantly improving corrosion resistance. This article will briefly introduce whether 304 stainless steel welded pipe will rust.
