Galvanized steel:
Thin-walled stainless steel pipe: advantage - made of 304 stainless steel, corrosion-resistant, smooth surface without scaling, superior comprehensive performance, but expensive;
Bi-metal composite steel pipe: It is a new type of composite water supply pipe that strongly fits galvanized steel pipe or welded pipe, seamless steel pipe and stainless steel pipe with thinner wall, and it is also a more ideal pipeline upgrade product. It retains the inherent advantages of two different materials, complements their inherent shortcomings, and follows the traditional and mature installation methods and processes of galvanized steel pipes, so it is convenient, reliable, hygienic and safe in use. According to the difference in the selection of base pipe and lining pipe, as well as the improvement of the manufacturing process, the bimetallic composite pipes produced by many manufacturers have been widely used in oilfield, chemical, electric power and other industrial fields. The economic, environmental and social benefits are also more obvious.
