Cold drawn (rolled) seamless steel pipe production methods round tube → heating → perforation → Heading → annealing → pickling → oiled (copper) → multi-pass cold drawn (cold) → billet tube heat treatment → → straightening → hydrostatic testing (testing) → mark → storage 12cr1mov high alloy pipe is a pipe can succeed under pressure, the use of this precision steel pipes to transport liquid wholesale, many of its kind, there are steel, brass, stainless steel, and Other more. Steel to heat treatment delivery. In addition, finished steel microstructure, grain size, decarburization there are certain requirements. 12cr1mov high alloy tubes are fully applied to all walks of life. Geological drilling and oil drilling control with seamless steel tubes; In order to investigate the structure of underground rock, groundwater, oil, gas and mineral resources, the use of drilling rigs. Oil, natural gas wells can not be separated precision steel, petroleum geology Drilling rigs drilling seamless precision steel is the main manufacturer of drilling equipment, including the core of the outer tube, inner core pipe, casing, drill pipe, etc. . Because drilling pipe to go deep into the depth of several kilometers formation work, working conditions is extremely complex, drill withstand tension and compression, bending, twisting and uneven stress impact loads, etc., but also by the mud, rock wear, therefore, require pipe must have sufficient strength, hardness, wear resistance and toughness, steel chemical composition and in addition have to permit a variety of mechanical properties of cold-drawn precision steel tubes, but also to ensure the water pressure, flattening, flaring and other tests, and the surface quality and non-destructive testing. In the heat pipe delivery status. Stainless steel pipe: stainless steel with a variety of hot-rolled, cold-rolled stainless steel pipe, stainless steel structural components are widely used in petroleum, chemical equipment, pipelines, and various uses, in addition to the chemical composition and should ensure that the mechanical properties, where the fluid is used to withstand the pressure of steel To ensure the water pressure test pass. Variety of special steel according to the provisions guarantee conditions.
