The difference between stainless steel tube and stainless steel composite tube
Stainless steel composite pipe: The material is iron pipe, which is covered with stainless steel layer. It is relatively strong. When the pipe mouth is well sealed, the rust-proof period is guaranteed to be the same as that of pure stainless steel.
Stainless steel pipe: The whole pipe is lighter in stainless steel, and the bearing capacity is not as good as that of composite pipe, but it is not easy to rust. The stainless steel material is divided into several kinds of 200, 201, 300, 301, 304, etc., and the market is generally 301 material. 304 works best, followed by 301.
