ASTM A995 6A dual plate check valve is a valve made of ASTM A995 6A material.
ASTM A995 6A super duplex stainless steel appeared in the form of cast steel in the mid-1980s. The development goal is to solve the harsh media (containing chloride, CO2, H2S, etc.) materials used in subsea oil and gas fields, instead of local corrosion resistance and uniform corrosion resistance. Insufficient Zeron25 (25Cr-6Ni-2Mo) duplex stainless steel. ASTM A995 6A steel has been used in many fields, mainly for its high strength and resistance to local corrosion and stress corrosion of chloride. Steel contains higher nitrogen, which has the effect of stabilizing austenite. Although the content of chromium and molybdenum elements are high, due to the effect of nitrogen, when the temperature is higher than 1050 ℃, the amount of ferrite is still close to 50%.
Due to its good mechanical properties and corrosion resistance, duplex stainless steel has been widely used in offshore engineering and shipbuilding, such as offshore oilfield gas, water systems, deep water pumps, offshore drilling platforms, subsea mining equipment, warships and special ships Wait. Although ASTM A995 6A duplex stainless steel material has high corrosion resistance, it is still a biologically inert material, which can only effectively slow down the rate of microbial corrosion, and still cannot solve the harm caused by microbial corrosion from the root cause.
The dual-plate check valve opening and closing member is opened or closed by the medium flow and the force to prevent the back flow of the valve from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only the media to flow in one direction to prevent accidents.
Newsway Valve ASTM A995 6A dual plate check valve opening/closing parts are opened or closed by the medium flow and force to prevent the medium from flowing back. Dual plate check valves belong to the category of automatic valves, which are mainly used for pipelines with one-way flow of media, and only allow media to flow in one direction to prevent accidents. The check valve butterfly plate is two semicircles, and the spring is used to force the reset. The sealing surface can be the body’s surfacing welding wear-resistant material or rubber lining. It has a wide range of use and reliable sealing.
