ASTM A182 F51 Flanges

Specialized Duplex Steel F51 Flanges Manufacturer, ASTM A182 F51 Flanges.

Marcel Piping Systems Supply PVT LTD is a well- known supplier and Exporter of Duplex Steel flanges that connect or attach varied valves, pipes and other equipment together. We’re manufacturing Duplex Steel flanges in different Alloy, material, norms and specifications as per the demands in industries. We’re using a pure quality Duplex Steel F51 grade for the manufacturing of all types of flanges. F51 duplex steel is one of the popular grades of duplex steel that contain both ferric and authenticate micro structure. It contains chromium, molybdenum, nickel and other essentials. The exceptional chemical composition of this grade offers excellent erosion resistance. We’re offering Duplex Steel F51 Flanges that provides bettered resistance to chloride attack and stress erosion cracking. Our flanges have high tensile strength and continuity to sustain in harsh environmental conditions. Our offered range of duplex steel flanges is largely resistant to bending, sulfide stress erosion and crack cracking. These flanges supply a significant seal and prevent leakage.

We are leading Stockists and Suppliers of ASTM A182 Duplex F51 Flanges in USA, UK, Qatar, Mexico, Nigeria, Saudi Arabia, Kuwait, Iran, Kazakhstan, Bahrain, Vietnam, Indonesia, Norway, Ghana, Colombia, Azerbaijan, Libya.
