Forged Steel Gate Valve

Aug 13, 2017

               Forged STEEL Gate valve: Is all uses the forging material processing to become the gate valve collectively is the forged steel gate valve, the forging material has A105, F11, F5, 304, 304L, 316, 316L and so on. Domestic often said that the forged steel gate valve usually refers to the small-caliber forged steel gate valve, the caliber range: dn10~dn50; pressure range: GB pn16~pn320, American Standard: class150~2500, can adopt the U.S. standard or GB size production and processing, manufacturers have spot supply. The forged steel Gate valves exceeding the DN50 caliber need to be ordered and the domestic demand is less.Forged Steel Gate Valve

              There are many different ways of the structure classification of Gate valves, the main difference is that the sealing elements used are different in structure form, according to the structure of the seal components, the gate valve is often divided into several different types, and the most common form is the parallel gate valve and the gate valve; According to the structure of the stem, can also be divided into the Ming rod gate valve and the dark rod gate valve FORGED STEEL GATE valve use: Forged STEEL gate valve is Working temperature -29~425℃ (carbon steel) or -29~500℃ (stainless steel) Small-caliber pipe, used to truncate or connect the pipeline medium, choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. Applied more on oil pipelines.Forged Steel Gate Valve

              Forged STEEL Gate Valve features: Forged steel gate valve mostly for the Dalian-type necking design, compared with the same caliber of the cast steel gate valve is slightly smaller, but the pressure and temperature range than the cast steel valve to be higher, the sealing performance is much better than the cast steel gate valve, longer life, medium flow direction and other gate valve as unrestricted.Forged Steel Gate Valve

             Installation point 1, installation location, height, import and export direction must meet the design requirements, the connection should be firmly close. 2, installed in the insulation pipe of various types of manual valves, the handle can not be downward. 3, the valve must be installed before the appearance inspection, the valve nameplate should conform to the current national standard "common valve mark" GB12220 provisions. For the work pressure is greater than 1.0MPa and in the main pipe to cut off the role of the valve, the installation should be carried out before the strength and tightness test, qualified after the use. Strength test, the test pressure is 1.5 times times the nominal pressure, the duration is not less than 5min, valve shell, filler should be no leakage for qualified. In the tightness test, the test pressure is 1.1 times times the nominal pressure, the test pressure should conform to the GB50243 standard in the duration of the test, and the sealing surface of the gate board is qualified without leakage. Standard for implementation of forged steel gate Valves.Forged Steel Gate Valve
