High pressure alloy tube

A high-pressure alloy tube is a tube that can be subjected to pressure. The tube is used to transport liquid. There are many types of steel tubes, copper tubes, stainless steel tubes, and the like.

High-pressure alloy pipe: high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless pipe used for steam boiler pipes mainly used to manufacture high pressure and above. These boiler tubes work under high temperature and high pressure by the party. The pipe will also oxidize and corrode under the action of high temperature flue gas and water vapor. Therefore, the steel pipe is required to have high durability, high oxidation resistance and good structural stability. The steel grade is: high quality carbon. 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 It is necessary to do the hydraulic test one by one, and to make the flaring and flattening test. The steel pipe is delivered in a heat treated state. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Geological drilling and seamless steel pipe for oil drilling control; drilling wells are used to find out the underground rock formation structure, groundwater, oil, natural gas and mineral resources.
