The surfacing flange produced by our company is based on carbon steel or alloy steel, and is lined with a certain thickness (generally 2-3mm) of stainless steel, titanium alloy, copper, aluminum and other corrosion resistant composite metal in its inner hole surface and the sealing surface of the flange. This special structure makes it take into account the pressure resistance of carbon steel and the corrosion resistance of stainless steel as well as the characteristics of relatively low stainless steel. Its outstanding cost performance and corrosion resistance make it in the oil and gas industry, water supply engineering, chemical industry and other industries have a wide range of applications.
