Seawater desalination plants. Main Material: Duplex Steel: ASTM A890/A995 4A, 5A, Duplex 2205 (UNS S32205 / S31803)/DIN1. Contact us to find out more details. Other body, gland and gate materials are available upon request. Stainless Steel Plate. The corrosion rate for duplex is 23 mil/year; AL6XN is 17 mil/year. End Cap: CF8, CF8M 4. ▤ Production R&D & Own Factory. Compared with austenite, The coefficient of thermal expansion is lower and the thermal conductivity is higher. 4462 ASTM: A240, A276, A479, A789, A790, A182 (Grade F51), A923. DBV can produce valves with various end connection, such as RF, RTJ, BW, NPT, Rasied Face is the most common type used in process plant applications. In lift Check valves, the disc is precisely guided and fits perfectly into the dashpot. Features: Duplex stainless steel ball valves are more and more popular used for high corrosion applications.
Due to the characteristics of the two-phase structure of duplex stainless steel, through correct control of chemical composition and heat treatment process, duplex stainless steel can have the advantages of ferritic stainless steel and austenitic stainless steel. Full Bore or Reduced Bore. At the opening position, the swing type check valve offers very little resistance to the flow. Connection: RF, FF, RTJ, G&T Flange Type. The properties and composition of the gate valve material is very important, especially since they are required to carry a range of liquids or gases that could affect certain substances. Usually, the non slam check valve is designed with an internal spring to opposing the opening flow pressure from upstream. Alloy 410 Stainless Steel Properties and Composition. Many standard body, packing gland options are available including 304, 316, 317, 254-SMO, 2205 Duplex Stainless Steel, Hastelloy C 276.
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. NOTE: The information and data in this product data sheet are accurate to the best of our knowledge and belief, but are intended for informational purposes only, and may be revised at any time without notice. D11015 - IM VALVE KGC 22", 26"-48" ES OR HD. Temperature Range: -20°C to 180°C. In the composition disc, the disc has a flat face that is pressed against the seat opening like a cap. End Connection according to ASME B16. BALTIC VALVE CO., LTD supplies superior quality industrial valves covering ball valves, globe valves, gate valves, check valves, plug valves, butterfly valves, marine valves, forging steel valve, filter, etc. THINKTANK provides many options for special materials and surface treatments to protect equipment, even in the harshest conditions. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. • Chemical processing, transport and storage. To achieve optimal performance, usually will use a lever and weight hammer or a lever with springs to quickly close the valve. Some of the corrosive environments listed below depict these differences. Marine environments.
4 Bolt: A193 B16 Gasket: Stainless Steel+Graphite Backseat: A182 F51, F53, F55 Bonnet: A890 4A, A890 […]. Duplex Dual Plate Wafer Check Valve Body: Duplex Stainless Steel, Alloy Steel, Super Duplex, Inconel, Incoloy, Titanium Disc: Duplex Stainless Steel, Alloy Steel, Super Duplex, Inconel, Incoloy, Titanium Seat: Metal Seated, BUNA, EPDM, VITON Nominal Size: 2″ to 24″ Nominal Pressure: PN16, PN10, Class150 Design and Manufacture Standard: API 594 End Dimension: ASME B16. To learn more about this material, click 410 stainless steel properties and click here to request a quote on pricing and delivery for type 410 stainless steel sheet and plate. However, other terms can be accepted upon request. If you need it one day in the future, we do appreciate it for your kindness. Duplex alloys are in a class with several other materials for various types of corrosion resistance.
Alloy 410 is a general purpose stainless steel with 12% chromium martensitic properties. ▤ Special Notes: We also can do special material according to customer\'s requirements. This type of seat arrangement is not as suitable for high differential pressure throttling. Cast stainless steel corrosion resistant valves. Chemical composition: C≤0. Due to raw material made of duplex stainless steel, so it has excellent performance of corrosion-resisitant. The elements that provide the strength and corrosion resistance in duplex are much more common than those found in some high-nickel alloys.
This type of seat provides maximum resistance to the erosive action of the fluid stream. Also, the duplex steel ball valves are particularly resistant to not only chloride stress corrosion but also chloride pitting corrosion. Used in a variety of industries, gate valves are best suited for applications where fluids or gases flow in a straight line and need minimum restriction. The gate valve has well cut-off or shut-off features. What is your quotation term? 34 / EN 12516-1 / JIS B2220. Duplex Steel Valves: Ball Valves, Gate Valves, Globe Valves, Check Valves. Category: Gate, globe, and check valves. 20 (austenite-ferrite type). Gate valve is a linear type on/off valve, but the ball valve is a rotary type on/off valve.
