Product details

Industrial stainless steel pipes: Industrial stainless steel pipes mainly include 304, 304L, 316, 316L and other materials. These materials have the characteristics of corrosion resistance, high temperature resistance, pressure resistance, etc., and are widely used in petroleum, chemical industry, papermaking and other industrial fields.

The surface of the industrial pipe is normally acid white surface, that is, pickling surface, because the application environment of the pipe is more humid, high temperature, some objects have corrosion performance, so the anti-oxidation requirement is very high, so pickling passivation can generate a dense oxide film on the surface of the pipe, which greatly improves the corrosion resistance of the pipe. A small number will have black tubes, and sometimes the surface will be polished as needed.
