Duplex Steel Ball Valve and Super duplex Ball Valves have higher strength and better stress corrosion cracking resistance than most austenitic alloys and greater toughness than ferritic alloys, especially at low temperatures.

Duplex Steel Ball Valve and Super duplex Ball Valves are best suited for some robust applications in the heavy engineering industry. For example, mining, petrochemical, engine, marine, pulp & paper industries are in need of super duplex steel ball valve for its superior quality & unique features.

Duplex Steel 

Duplex stainless steels are Fe-Ni-Cr alloys consisting of ferritic-austenitic microstructure at room temperature. These steels generally possess beneficial combinations of the austenitic and ferritic phases. Duplex stainless steels exhibit greater toughness and better weldability than ferritic stainless steel. They have higher strength and better corrosion resistance than austenitic stainless steel.

Duplex Steel Ball Valve Application

Their good engineering performance has led to an increasing number of applications, mainly in corrosive environments such as sour gas pipelines and chemical reaction vessels, and sea water.

Super Duplex Steel 
The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid.
Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.

Super Duplex Steel Ball Valves Application
Oil and gas industry equipment, Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems, Chemical process industries, heat exchangers, vessels, and piping, Desalination plants, high pressure RO plants and seawater piping, Mechanical and structural components, high strength, corrosion-resistant parts, Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping.
