Super Duplex Applications
FASTWELL is engaged in manufacturing and exporting a qualitative range of Duplex Steel Pipes that are widely used in construction & other industries. These super duplex seamless pipes possess high resistance against corrosion and are available in various grades and specifications. Our super duplex steel pipes are quality tested on various parameters as per ISO and international standards before being delivered to our clients.
Applications of Super Duplex steel piping is involved in various fields such as Oil and gas industry equipment, absorber towers, ducting, and piping, Mechanical and structural components, high strength, corrosion-resistant parts, Desalination plants, high pressure RO-plants and seawater piping, Chemical process industries, heat exchangers, vessels, and piping, Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems,
Power industry FGD systems, utility and industrial scrubber systems and so on.
Super Duplex pipes are designed to provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, and higher strength than standard austenitic stainless steels. A 22% Chromium duplex stainless steel pipe has a minimum 0.2% proof strength of some 450N/mm2. Duplex SS pipe PREN is calculated from a simple formula: PREN = %Cr + 3.3%Mo +16%N and an allowance for W is sometimes made, having a factor of 1.65.
