Precision seamless steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. Because there is no oxide layer on the inner and outer wall of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no crack, it is mainly used to produce products of pneumatic or hydraulic components, such as air cylinder or oil cylinder. It is widely used in hydraulic system steel pipe, injection molding machine steel pipe, hydraulic machine steel pipe, shipbuilding steel pipe, EVA foam hydraulic machinery, steel pipe for precision hydraulic cutting machine, shoe making machinery, hydraulic equipment, high pressure oil Pipe, hydraulic oil pipe, ferrule joint, steel pipe joint, rubber machinery, forging machinery, die-casting machinery, engineering machinery, high-pressure steel pipe for concrete pump truck, sanitation vehicle, automobile industry, shipbuilding industry, metal processing, military industry, diesel engine, internal combustion engine, air compressor, construction machinery, agricultural and Forestry machinery can completely replace the imported seamless steel pipe of the same standard.Characteristic: 1. High precision, saving the consumption of labor and materials in machining. 2. Many specifications and wide application range. 3. The cold rolling product has high precision, good surface quality and good straightness. 4. The inner diameter of steel pipe can be made into hexagon. 5. The performance of steel pipe is superior and the metal is relatively dense. Process flow of precision steel pipe: Tube blank -- Inspection -- peeling -- Inspection -- Heating -- piercing -- pickling passivation -- grinding -- lubrication and air drying -- cold rolling -- degreasing -- cutting -- Inspection -- marking -- finished product packaging Precision steel pipe is widely used in automobile, motorcycle, electric vehicle, petrochemical, electric power, ship, aerospace, bearing, pneumatic components, seamless steel pipe of medium and low pressure boiler, and can also be used in steel sleeve, bearing, hydraulic, mechanical processing and other fields
