Duplex Flanges
Equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries often includes Flange Duplex S31803 Welded. The addition of molybdenum and a slightly higher nickel content make Duplex Steel Flange S31803 Blind suitable for harsh architectural applications, from polluted marine environments to sub-zero temperatures. Duplex Steel UNS SS3180300 Socket Weld Flanges also offer superior creep strength, tensile stress and tensile strength at elevated temperatures, excellent corrosion resistance and strength properties, and are excellent for fabricated or molded applications. Duplex Steel Flanges S31803 Lap are ideally suited for applications that require a higher corrosion resistance than Type 316 and have good resistance to elevated temperatures. Duplex Steel Flange S31803 Ring Joint is a lower carbon version and is resistant to allergies. Therefore, Duplex Steel S31803 eyeglass collars are very often used in high thickness welded parts. Duplex Stainless Steel flanges S31803 are considered to be resistant to pitting corrosion in drinking water with chlorides at ambient temperature, decreasing at 60 degrees C.
Super Duplex Flanges
The Super duplex microstructure gives these Super Duplex Steel Flanges S32750 Sliding a low coefficient of thermal expansion and a higher thermal conductivity than austenitic steels and is suitable for operation up to 300 degrees C. Our Flange Super Duplex Steel S32760 threaded is often used in the marine and shipbuilding industries. For example in propellers and shafts, rudders, shaft seals, pumps, bolts and fittings, valves, instrumentation, tankers and chemical tankers. Meanwhile, these Super Duplex Steel Flanges S32750 Welded are also offered to our customers in various sizes and shapes. As our Super Duplex Flanges S32760 blind are significantly better than SS 316L or SS 904L in this situation, they are a good candidate for wet process phosphoric acid applications. We are one of the pioneering manufacturers and suppliers of our Super Duplex Steel Flanges, which are prone to losses leading to non-chromium carbide precipitation. The very low carbon content of these Super Duplex Steel Flanges S32760 Lap combined with overall very good corrosion resistance make the steel substantially resistant to intergranular corrosion caused by precipitation of chromium carbide. We are supplying to Asia, USA, Africa and Europe including Germany, Belgium, Italy, Turkey, Denmark and UK
