Naman Duplex - Model DSS -Flanges
Flanges are fixtures that are employed in connecting piping fixtures of different sizes. Duplex Flanges provide support and stability to different applications during the vigorous flow of media. Designed with a ferritic and austenitic microstructure the Duplex Steel Flanges have a superior composition of nickel, chromium, and molybdenum, giving them enhanced corrosion and oxidation properties.
The Duplex Steel Reducing Flanges are seen in joining piping fixtures of dissimilar sizes and shapes. These flanges are designed in concentric and eccentric configurations. Duplex Steel Forged Flanges are processed at extreme pressures and temperatures. These flanges have a higher tensile and fatigue strength. We are the duplex flanges manufacturers in India who supply quality assured products across all our outlets at the most reasonable prices.
The Duplex Steel Slip On flange is one of the most common flange type in the industry. These flanges are welded in place using one or more fillet welds. They are seen in low pressure and temperature applications. DSS weld neck flange is a high-strength grade that provides stability to different fixtures during the vigorous flow of fluids and gases in the system. The Duplex Steel Long Weld Neck Flanges are similar to weld neck flanges and have a longer hub or face type. The neck in these flanges acts as a boring center and provides stability to different applications. A DSS Blind Flange, on the contrary, is designed without a face type or boring center. These flanges help in terminating gaseous and fluid flow in the system. The robust flanges are easy to clean and maintain. The versatile DSS Spectacle Blinds have an open end with a spade. They are generally seen in units where maintenance or repair is done in the system. A Duplex Socket Weld Flange is seen in small sizes for high-pressure systems. These flanges are inserted in a socket area and welded using a single fillet weld.
