St52 Cold Drawn Seamless Steel Pipe For Hydraulic Automobile

Made in China St37 St52 Cold Drawn Seamless Steel Pipe Factory For Hydraulic/Automobile Pipe

Stainless steel pipe is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used as furniture and kitchenware.Use high quality carbon structural steel hot rolled or cold rolled (dial) seamless steel tubes. Mainly made of 10, 20 steel, in addition to ensure chemical composition and mechanical properties to do water pressure test, crimping, flaring, flattening and other tests. Hot rolling in hot rolling state delivery, cold rolling (dial) in heat treatment state delivery. High pressure boiler seamless steel tube: Mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless Heat resistant steel seamless steel tube, these often under high temperature and high pressure boiler tube, tube in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance, And has good organizational stability, using steel: high quality carbon structural steel steel 20G, 20MnG, 25MnG; Alloy structure steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; Rust heat resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high pressure boiler pipe in addition to ensure the chemical composition and mechanical properties, to do water pressure test, to make flaring, flat test. Steel tubes are delivered in heat treatment condition. In addition, the microstructure, grain size and decarburization layer of finished steel tubes are also required. Geological drilling and oil drilling seamless steel pipe: in order to explore the underground rock structure, groundwater, oil, natural gas and mineral resources, the use of drilling Wells. Oil and natural gas exploitation is inseparable from drilling, geological drilling with oil drilling with seamless steel pipe is the main drilling equipment, mainly including core outer pipe, core inner pipe, casing, drill pipe, etc.. Due to the drilling pipe to work deep into thousands of meters of stratum depth, the working conditions are extremely complex, drill pipe under tensile, compression, bending, torsion and unbalanced impact load and other stresses, but also by mud, rock wear, therefore, the requirements of the pipe must have enough strength, hardness, wear resistance and impact toughness
