So how should we choose high-quality 304 stainless steel pipe? First, identify whether the steel stamped material "304" is printed on the surface of the pipe, and ask for the manufacturer's quality certificate and quality guarantee.

Secondly, check whether the color of the outer surface and the inner wall of the tube is bright and smooth, whether the thickness is uniform, or whether there is roughness. When purchasing, you should choose products above the provincial level that have been assessed by the Bureau of Quality and Technical Supervision. It is a direct and effective purchase method that has been used for a long time and has a good reputation among customers.
