Naman Duplex - Heat Exchanger and Boiler Tube

The Duplex Tubing possesses superior strength and has a higher fatigue resistance. These tubes have good working temperatures and have a larger thermal conductivity. Duplex 2205 tube has a minimum tensile strength of 90ksi with a minimum yield strength of 65ksi. They have a hardness of 32 max hardness RC and can be elongated by 25%. The S32205 Tube has a higher resistance to pitting and corrosive media compared to the S31803 tube. These tubes have a higher content of nitrogen in their composition, giving them better protection against harsh conditions. An S31803 Tube has a density of 7800 kg/m3 and showcases excellent weldability.

A Duplex Welded tube is produced as metal sheets or strips are rolled and subsequently welded to form the tube. These tubes are preferred in moderate to low pressure and temperature applications. The Duplex Seamless Tube, on the contrary, is designed without any welds or seams. Produced via the extrusion process, these pipes have 20% superior strength in comparison to welded tubes. These tubes are preferred in treacherous applications across different systems. Duplex Boiler Tube is a pressurized vessel grade that can withstand high as well as low pressures and temperatures. These tubes can withhold and process toxic fluid and media across vigorous conditions. The Duplex Heat exchanger tube is a versatile grade that is employed in transferring heat from two or more fluids. These tubes can be used for mixing hot and cold fluids and have good internal reliability. Duplex Coiled Tubing is a small-diameter continuous pipe that is used in drilling in oilfield technology and remediation techniques. We are leading Duplex Tube suppliers in India
