Duplex Stainless Steel Gate Valves Installation

Tuesday, 30 July 2024
The special structure and surface treatment of the disc carrier and pin eliminates the phenomenon of valve can close and open evenly to avoid the common defects of disc can not stay in the center of sealing position because of the gravity of disc. The main application of duplex steel ball valves includes oil&gas, seawater desalination, shipbuilding, pharmaceutical, petroleum, chemical, and so on. Duplex stainless steel cannot be hardened by heat treatment. Oil and gas refining. Due to the presence of austenite, duplex stainless steel reduces the brittleness of high-Cr ferrite and the tendency of crystal growth, while maintaining excellent toughness and welding performance; while the presence of ferrite increases the yield of austenite Strength, resistance to intergranular corrosion, and chloride stress corrosion resistance. There are 4 types of check valves we are familiar in the site. When the valve is fully opened, the sealing surface suffered small friction from the working medium. The duplex stainless steel ball valve is a ball-type on-off valve that uses a ball to control liquids. It consists of a guided disc that lifts up from the valve seat and creating space for medium to flow. Duplex's machining rate of travel is similar to that of 316 stainless steel with high-speed steel tooling, and duplex requires fewer machining labor hours than high-nickel alloys. Duplex stainless steel gate valves types. Duplex and super duplex stainless steel ball valves. Size range: NPS1/2"~48",DN15~DN1200.

Duplex Stainless Steel Gate Valves Types

Duplex grades can readily be used down to at least -50°C. Stem: SS304, SS316 5. 5A CE3MN and A890 Gr. There are many more types of corrosive conditions but these are some for which stainless and nickel alloys are suitable. For Duplex Stainless Steel: The microstructures consist of a mixture of austenite and ferrite phases.

Therefore, the duplex steel has both austenitic and ferritic stainless steel's properties. SIZE RANGE: 2-48" (50-1200mm). No limitation on the flowing direction of the medium. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels. The recommended filler material for 2205 stainless steel is 2209. 410 Stainless Steel Gate Valves. The principle of the check valve is working on differential pressure, it means the check valve only opens if the inlet pressure is over the outlet pressure. The closure component is a gate, that's why called a gate valve.
