SDSS Seamless Pipe and Super Duplex Tube supplier in India
Stockist & supplier of Super Duplex Heat Exchanger Tubes and SDSS Boiler Tube as per American standard ASTM A789/ A790/ A928 supply with MTC EN 10204 3.1, NACE MR0175
A SDSS grade is part of the stainless steel family that has enhanced functionality in the harsh environments. A Super Duplex Pipe is designed with an austenitic and ferritic microstructure giving them superior strength and load-bearing capacity. The Super Duplex Stainless Steel Pipe is manufactured with an outstanding chemical composition of nickel, chromium, and molybdenum with other constituents. This gives them good corrosion and oxidation resistance properties. The Super Duplex Stainless Steel Tube is a high-performance grade that has good strength compared to pipes in this grade. These tubes are designed in square, round, hexagonal, and other configurations. A Super Duplex Tube has a density of 7.8 g/cm3 and has a modulus of elasticity of 200GPa. These tubes possess excellent tensile and yield strength in different conditions. The Super Duplex Tubing is a quality-assured grade that is designed with the best raw materials and latest technology under the guidance of our renowned customers.
A Super Duplex Welded Pipe is produced as metal is rolled and subsequently welded using standard welding procedures. These pipes offer a cost-effective solution and are very reliable in their functionality. The Super Duplex Seamless Pipe is designed without any welds or seams. These bars are produced via the extrusion process and have superior strength compared to welded pipe fixtures. A Super Duplex Boiler Tube is designed to process high pressure and temperature fluids and gases. These tubes are employed to heat water and subsequently form steam in the system. The Super Duplex Heat Exchanger Tubes are versatile components that pass pressurized fluid. These tubes are highly resistant to thermal shock and have no dimensional limit.

What is Super Duplex Pipe
The term "SDSS pipe" refers to a type of DSS pipe. SDSS Pipe is a material that combines the properties of ferritic and austenitic steels. As a result, the ferritic structure provides great strength while the austenitic structure provides high corrosion resistance.
