National standards for copper pipes and stainless steel pipes, and the implementation standards for

There are thousands of stainless steel pipe specifications, and there are mainly three kinds of commonly used decorative pipe materials, from small diameter to large diameter, such as diameter 10mm, 19mm....It is recommended that if you purchase decorative stainless steel pipes to ask for specific thickness, the actual standard thickness will be better.

The national labeling of steel pipes can be divided into:

1. Hot-rolled seamless steel pipe (GB8162-1987) (GB8163-1987) 2. Galvanized welded steel pipe and welded steel pipe for low-pressure fluid transportation (GB3091-1982) (GB3092-1982).

3. Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-1983) 4. Seamless steel pipe for low and medium pressure boiler (GB3087-1982).
