Duplex 2205 Tubing and Duplex Heat Exchanger Tubes Manufacturer in Mumbai, India


Duplex steel is well suited for applications involving flue gas, mainly because the material is a corrosion resistant one. Flue gas contains the emissions of various corrosive material such as sulfur dioxide, mercury, nitrogen oxides as well as carbon dioxide. The deposition of such corrosive chemicals causes harm to the pipes made from regular steel. Therefore, most duplex stainless steel tube manufacturers across the world suggest the use of alloy 2205 in flue gas applications. Flue gas is highly toxic and must not be released into the environment.

Duplex Stainless Steel Heat Exchanger Tubes

The use of a durable Duplex S31803 Tube ensures a leakproof transmission. The material has superior tensile strength, in addition to outstanding corrosion resistance properties, making the Duplex Stainless Seamless Tube a more durable and viable option. Since power plants have cleaning procedures set in place for flue gas residual compounds from the piping system, the Duplex Heat Exchanger Tubes are treated to a solution of carbon and lime milk, which is sprayed. These chemicals themselves are concentrated and generate some amount of heat. Ordinarily, steels react with these chemicals, due to the deposition of the lime residue, which in turn may result in the formation of toxic chemicals. The use of a Duplex 2205 Seamless Tube, not only promotes smooth functioning of the application, but it also permits the buyer with a thorough cleaning process, on account of its smooth, internal surface. Along with a higher PREN value, the Duplex Stainless Steel Tube is not prone to stress related corrosion cracking, especially in applications that contain chloride and sulfide in their environments. The Duplex 2205 Tube also has high tensile strength and offers resistance to crevice corrosion. Duplex Stainless Steel Pipe is a grade of tubular products. Perfect Impex is a large supplier of all kinds of 2205 Duplex Stainless Tubing Dimensions.
