12Cr2Mo/15Cr5Mo Gas Fire Extinguishing High-Pressure Tee Forged Steel Fittings

Gas fire extinguishing high-pressure pipe is a kind of pipe that can withstand high-strength pressure. This pipe is used to transport liquids. There are many types of steel pipes, copper pipes, stainless steel pipes, and others.
Gas fire extinguishing high-pressure pipe fittings: high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes mainly used to manufacture high-pressure and above steam boiler pipes. These boiler pipes are under high temperature and high pressure. Work and pipes will also undergo oxidation and corrosion under the action of high-temperature flue gas and water vapor. Therefore, steel pipes are required to have high durability, high oxidation resistance, and good structural stability. The steel grades used are: high-quality carbon Plain structural steel grades are 20G, 20MnG, 25MnG; alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust-resistant heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high pressure pipe to ensure chemical composition and mechanical properties In addition, it is necessary to do a water pressure test one by one, and do a flaring and flattening test.
Steel pipes are delivered in a heat-treated state. In addition, there are also certain requirements for the microstructure, grain size, and decarburized layer of the finished steel pipe. Seamless steel pipes for geological drilling and oil drilling control; use drilling rigs to drill wells for the exploration of underground rock structure, groundwater, oil, natural gas and mineral resources. Petroleum and natural gas exploration is even more inseparable from well drilling. Seamless steel pipes for geological drilling and control are the main equipment for drilling, including core outer pipe, core inner pipe, casing, drill pipe, etc. Because drilling pipes need to be deep into the formation depth of several kilometers, the working conditions are extremely complicated. The drill pipe is subjected to stresses such as tension, compression, bending, torsion, and uneven impact load, and is also subject to mud and rock wear. Therefore, pipe materials are required It must have sufficient strength, hardness, wear resistance and impact toughness. The steel used for steel pipes is represented by "DZ" (Geological Chinese Pinyin prefix) plus a number one representing the yield point of steel. Commonly used steel grades are 45MnB and 50Mn of DZ45; 40Mn2, 40Mn2Si of DZ50; 40Mn2Mo, 40MnVB of DZ55; 40MnMoB of DZ60, 27MnMoVB of DZ65. The steel pipes are delivered in a heat-treated state.
Petroleum cracking pipe: seamless pipes for furnace tubes, heat exchanger tubes and pipelines in petroleum refineries. Commonly used high-quality carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9, 1Cr18Ni9Ti) manufacturing. In addition to the certified chemical composition and various mechanical properties of the steel pipe, it is also necessary to ensure the water pressure, flattening, flaring and other tests, as well as surface quality and non-destructive inspection. The steel pipe is delivered under heat treatment.
Stainless steel pipe: Hot-rolled and cold-rolled stainless steel pipes of various stainless steels are widely used in petroleum and chemical equipment pipelines and stainless steel structural parts for various purposes. In addition to ensuring chemical composition and mechanical properties, they are used as steel pipes that can withstand fluid pressure. Ensure that the water pressure test is qualified. All kinds of special steel pipes must be guaranteed according to the stipulated conditions.
Gas fire extinguishing high-pressure pipe fittings products are widely used in high-pressure pipe network connections in construction engineering, post and telecommunications, communications, power stations, computer rooms, libraries, ships, high-rise buildings, petroleum, electric power, chemical engineering, urban construction, heating, light industry and other gas fire extinguishing projects
