Which is better for load-bearing performance in galvanized steel pipe or stainless steel pipe

Stainless steel welded pipe is increasingly used in our daily lives. There are both stainless steel and galvanized steel pipes. Some say galvanized steel pipe is cheaper, but I'm not sure if it performs well. Is it better than stainless steel?

First, what is a stainless steel welded pipe?

Stainless steel welded pipe, also known as welded pipe, is made from common steel or steel strip, formed by rolling it through a machine and a die. Welded pipe boasts a simple production process, high efficiency, a wide variety of specifications, and low equipment investment. With an increasing variety and specifications, it is replacing seamless steel pipe in a growing number of applications, particularly in heat exchange equipment, decorative pipes, and medium- and low-pressure fluid pipes.

Second, what is galvanized steel pipe?

Galvanized steel pipe is an ordinary steel pipe that has a coating of zinc paint sprayed on the surface. To prevent rust, even if this coating is removed, it will still rust.

Third, Differences in Application

- Stainless steel welded pipe: Primarily used in the petroleum, chemical, pharmaceutical, and food industries. Light industry. Industrial pipes for mechanical instruments, mechanical structures, and other conveying applications. Furthermore, its light weight, while maintaining the same bending and torsional strength, makes it suitable for manufacturing mechanical parts and engineering structures. It can also be used in decorative and furniture applications.

- Galvanized steel pipe: Welded steel pipe with a hot-dip or electro-galvanized surface. Hot-dip galvanized steel pipe is used in manufacturing industries such as construction, machinery, coal mining, chemicals, power generation, rail vehicles, the automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.

In general, stainless steel pipe can cover all the applications for which galvanized steel pipe is used. Galvanized steel pipe's performance is far inferior to that of stainless steel pipe, making it inadequate for more complex applications. Furthermore, stainless steel welded pipe has a longer service life and better corrosion resistance than galvanized steel pipe, leading to an increasing use of stainless steel pipe.
