As an example, machining of 2205 is around 20% slower than for 304. End Connection Type: Flange End, Socket Weld, Butt Weld End, Screwed, Etc. Size from 1/2in to 12in (DN15 to DN300). As you know the local market.. Duplex Steel Valves: Ball Valves, Gate Valves, Globe Valves, Check Valves. Contact us to find out more details. We train our technicians from time to time to master the professional technical knowledge to guarantee the quality of our 4-Way Stainless Steel Ball Valve, High Pressure Trunnion Ball Valve, Side Entry Trunnion Mounted Ball Valve.
The check valve is kind of a mechanical device used in pipeline systems. The closure is a disc swing on a hinge or shaft. The inlet pressure must be more than the cracking pressure to overcome gravity or a spring force. For more information, please send us your email. Size range: NPS1/2"~48",DN15~DN1200. Duplex stainless steel cannot be hardened by heat treatment.
Machining can be enhanced by using the following rules: Welding of Duplex stainless steel. 96 Fanhua East Road, OuBei, WenZhou, Zhejiang, China, 325102. The most affect shutoff characteristics of swing type check valve are the disc weight and backflow, so how to make the disc fast response and close tight is all the design factor. Duplex Valve Avaliabe In Stock - Fast Delivery. Pressure Rating: ANSI CL150 to CL900/ DIN PN10 to PN40/ JIS 10K to 16K. Acid and alkali corrosion resistance. 1A, 2A, 3A, 4A, 5A, 6A, 1B, 1C. 4A — alloy properties. Next: ASTM A890 5A Gate Valve, 10 Inch, 150 LB, RF, API 600, ASME B16. They have high resistance to intergranular corrosion.
The desalination process, especially the seawater reverse osmosis system(SWRO), requires a large number of valves that can treat large amounts of water under high pressure. 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. The pitting and crevice corrosion resistance of C276 and AL6XN are only slightly superior to the duplex alloys'. 10 / EN 558-1 / JIS B2002. There are many other duplex stainless steels, most of which are proprietary grades developed and produced by individual manufacturers. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface of the fabricated product. Chemical process plant. PRESSURE RATING: 2-48" (50-1200mm) - 150 psi C. W. P. (1030 kPa). Stainless Steel Plate. One of the key conditions of the check valve is at the pump downstream to protect the expensive and important equipment from flow reversal.
Compared with austenitic stainless steel, duplex stainless steel 2205 alloy has twice its compressive strength.

Both of these two methods will challenge our valves should meet corrosive environment, high salinity media, and cavitation.
Extended Service Cast Stainless Steel Knife Gate Valves (KGC-ES) Specifications. Manufacturer and supplier of industrial valves, including Floating Ball Valves, Trunnion Ball Valves, Flanged Gate Valves, Welded Gate Valves, High Pressure Gate Valves, Globe Valves, Swing Check Valves, Double Disc Wafer Check Valves, Y Strainers, etc. Standard connections. Z41H-16C Cast Steel WCB Rising Stem Hard Sealing Wedge Flange Type Manual High Temperature Resistant Gate Valve. Low emission packing can be chosen according to ISO 15848 requirement. They provide excellent hydrodynamic properties that result in very low-pressure losses and they are technically efficient. Applications that require the flow of heavy oils, light grease, cream, and other non-flammable liquids can benefit from using a gate valve as a shutoff device. Outside Screw & Yoke (OS&Y), Rising stem.
