不锈钢管和不锈钢复合管的区别

Difference between stainless steel pipe and stainless steel composite pipe

不锈钢复合管：材质为铁管，外面包裹着不锈钢层.

Stainless steel composite pipe: the material is iron pipe, which is wrapped with stainless steel layer

比较坚固，管口封闭良好的情况下可保证其防锈期限与纯不锈钢无异。

It is relatively strong and the sealing of the pipe orifice is good, which can ensure that its anti rust period is the same as that of pure stainless steel.
