In order to ensure that the material meets the standard, you can ask the merchant to issue a quality certificate and do a reagent test when choosing.

Check the surface: Check whether the color of the outer surface of the stainless steel tube and the inner wall of the tube is bright, smooth, uniform in thickness, or rough, because the stainless steel tube may have uneven thickness during the production and rolling process. In the same situation, there will be problems in the subsequent use and processing of the stainless steel tube.

The principle of purchasing is to save costs as much as possible on the basis of suitable specifications.
