Duplex Flanges

ASTM A182 DSS Slip-on and Blind Flange manufacturer in India

Great Steel & Metals is a leading Duplex Stainless Steel Pipe Flange Manufacturer. Our products are of superior quality and we have good stocks. There are different kinds of flanges and we make them all. The Duplex Blind Flange is good to terminate a pipeline because it is durable, ductile and much corrosion resistant. The duplex material has both austenitic and ferritic steel phases so that it is optimized for strength and corrosion resistance. Our Duplex Flange Pressure Rating is very high so that the duplex flanges could be used in high pressure applications. There are different standards to govern the pressure ratings. The ANSI B16.5 Duplex Stainless Steel Plate Flanges range from the pressure classes 150 up to 2500 and the standard covers pipes with nominal sizes from NPS ½ through NPS 24. The Duplex Stainless Steel Flange Material manufactured by us is by the international standards. We produce different grades of duplex steel that require different qualities to be used in different applications. The applications include marine and sea water piping, chemical and food processing plant piping, pollution control systems and others. The ASTM A182 Duplex Steel Socket Weld Flanges are used to connect two pipes with an additional socket holding them together. When these flanges are welded with the pipes, Duplex Weld Neck Flange can prove to be one of the strongest connection methods. We encourage our customers to contact us for any inquiries.
