Duplex Steel Valve
Speciality valve is one of the top Duplex steel valve manufacturer in India. Duplex steel valves are a type of valve made from a duplex stainless steel material. Duplex stainless steel is a mixture of austenitic and ferritic stainless steel, providing high strength and corrosion resistance properties. This combination makes duplex steel valves suitable for use in harsh environments and demanding applications, such as oil and gas, chemical processing, and marine applications.
Duplex steel valves typically have better resistance to corrosion, pitting, and stress corrosion cracking compared to other types of stainless steel valves. They also have high strength and toughness, making them suitable for high-pressure applications.
