Characteristic
Bright steel pipe is a kind of steel tube refined by cold drawing or cold rolling， oxidation-free bright heat treatment (NBK state)， non-destructive testing， the inner wall of the steel tube is brushed with special equipment and rinsed with high pressure， the steel tube is treated with antirust oil for rust prevention， and the ends are capped for dust-proof treatment.
TP321 stainless steel is an austenitic stainless steel with high chromium and nickel content and a small amount of titanium. This combination of materials gives TP321 stainless steel excellent corrosion and high temperature resistance， able to resist a wide range of strong acids， alkalis and other chemicals， while also withstanding high temperature oxidation and corrosion.
