Have you met tube edge deformation and tube bending problemsafter getting the goods ?

We give complete and several times of correcting for each tube with particular equipment during production, as well as proper packing to avoid edge deformation or bending before delivery.

Have you got the problems from unacceptable tolerance when you are checking the stainless steel pipes from your previous supplier ?

With our tolerance control machine equipments, strict inspection process has been proceeded to make sure our stainless steel pipes produced and finished by all standards of ASTM, EN, JIS etc.

Have you ever met defective and such a bad surface finish ?

There must be complete pickling process given during our stainless steel pipes’ production. And we also provide stainless steel pipe surface treatment requirement from our clients, such as polishing, grinding,hairline etc.
