Duplex Fittings

ASTM A815 DSS Elbow and Reducer Pipe Fittings Manufacturer in India

Duplex Fittings

Great Steel & Metals is a Duplex Fittings Manufacturer that produces all kinds of pipe fittings in the duplex steel grade. We accommodate custom order and provide customers with the best quality products. There are different grades and standards of duplex and the pipes have different dimensions. The ANSI B16.9 Duplex Steel Pipe Fittings range from small to 48 inches diameter pipes and fittings. These highly corrosion resistant components and are used in different applications that need to have corrosion resistant material. The Duplex Fittings are strong and durable so that they could be used in sea water, marine, food processing and chemical industries. The use of Duplex Stainless Steel Elbow is necessary to change the direction of the piping usually in either 90 degrees or 45 degrees angles. There are different grades such as the ASME SA815 Duplex Pipe And Fittings which are super strong and can be used in high temperature applications. There are different types of fittings in the duplex grade as well. Couplings, nipples, unions, elbows and bend are some of them. We manufacture all kinds of pipe fittings. The Duplex Steel Pipe End Cap is used to terminate a connection. Threaded caps are used to fit threaded pipes and for permanent closures, the caps are welded. The reducers are used for alternating pipe sizes. The Duplex Steel Reducer Dimension differs from standard to standard. We are happy to provide with a full catalogue of our duplex pipe fittings upon inquiry.
