ASTM A106 Seamless Steel Pipe 1mm - 80mm Thickness For Oil Gas Line

1 - 80 Mm Thickness ASTM A106 Seamless Steel Pipe For Oil And Gas Line

General seamless steel pipe: it is made of 10, 20, 30, 35, 45 and other high-quality carbon bonded steel 16Mn, 5MnV and other low alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot rolled or cold rolled. 10, 20 and other low carbon steel manufacturing seamless pipe is mainly used for fluid pipeline. 45, 40Cr and other medium carbon steel made of seamless pipe to manufacture mechanical parts, such as cars, tractors stressed parts. The general use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel pipes are delivered in hot rolled or heat treated condition. Cold rolled delivery is heat - treated. Seamless steel pipe for low and medium pressure boiler: used for manufacturing all kinds of low and medium pressure boiler, superheated steam pipe, boiling water pipe, water wall pipe and superheated steam pipe, big smoke pipe, small smoke pipe and arch brick pipe for locomotive boiler. 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, Steel pipe steel with "DZ" (geological Chinese pinyin head) plus a number on behalf of the steel yield point, commonly used steel DZ45 45MnB, 50Mn; DZ50 40Mn2, 40Mn2Si; DZ55 40Mn2Mo, 40MnVB; DZ60 40MnMoB, DZ65 27MnMoVB. All steel tubes are delivered in heat treatment condition.
