Guidelines for the selection and use of stainless steel pipes

1. Make sure that the material meets the standards when selecting steel pipes. Take 304 material as an example:
a. From the price analysis, if the 304 material sanitary stainless steel pipe is even lower than the general price of the 301 material on the market, it must be carefully distinguished, it is likely that other materials are counterfeiting;
b. Identify whether the steel stamped material “304” is printed on the surface of the pipe, and obtain the manufacturer’s quality certificate as a voucher;
c. It can be tested with acidic reagents, the material 304 will not change color after 30 seconds, and 201 will turn black;
d. Samples can be drawn for mass purchase and sent to the national authoritative testing center for component analysis and testing.

2. Observe whether the color of the outer surface and the inner wall of the tube is bright and smooth, whether the thickness is uniform or rough. Generally, welded pipes basically do not need to be inspected, and seamless steel pipes are produced by cold drawn or hot rolled methods. Improper operation in the production process is prone to uneven thickness and cracks on the pipe surface. Rough surface is generally seamless pipe. No polishing treatment, if there is no special requirement on the appearance, it will not affect the use.

3. When purchasing, choose products that have been assessed by the Bureau of Quality and Technical Supervision. Long-term use testimony and good reputation among customers is a direct and effective way to purchase.

4. Internal heavy leather, pitting, and rolling blue lines often appear in rolled pipes. Under normal circumstances, these cannot be avoided and basically do not affect the use, but you must choose as few as possible when purchasing, especially checking The inner surface.
