High-pressure alloy steel tube is a kind of pressure to the tube, its excellent performance to win the majority of users praise, then the high-pressure alloy tube in the end what purpose?
High-pressure alloy steel tube used to make high pressure and above the pressure of the steam boiler pipe and other high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless pipe, the boiler tube by the party at high temperature and high pressure work, High temperature flue gas and water vapor will occur under the action of oxidation and corrosion, so the requirements of steel pipe with high lasting strength, high oxidation resistance, and has good organizational stability. High pressure pipe in addition to ensuring the chemical composition and mechanical properties, the water pressure test to be done, to be flaring, flattening test. The steel pipe is delivered in heat treatment. In addition, the finished steel pipe microstructure, grain size, decarburization layer also has certain requirements. Geological drilling and oil drilling and control of seamless steel pipe; to explore the underground rock structure, groundwater, oil, natural gas and mineral resources, the use of drilling rig drilling. Oil and natural gas mining is more inseparable from drilling, geological drilling and control oil drilling with seamless steel pipe is the main equipment drilling, including the core of the outer tube, core tube, casing, drill pipe and so on. As the drilling pipe to deep into the depth of several kilometers to work, the working conditions are extremely complex, drill pipe to withstand pull, pressure, bending, torsion and uneven impact load and other stress.
