1. Production process of precision steel pipe
The production process of precision steel pipe is the same as that of ordinary seamless pipe, that is, there is a final process of pickling and cold rolling.
Precision steel pipe process
Tube billet heating - inspection - skin - - - perforation, pickling passivation, grinding - oil lubrication dry - cold rolled - to - cut head - inspection, identification, finished product packaging
Chinese Precision Steel Pipe factory. As a professional Precision Steel Pipe Manufacturer, we strictly follow this processing process.
2. Product characteristics of precision steel pipe
(1) Smaller outer diameter.
(2) High precision can do small batch production.
(3) High precision and good surface quality of cold drawing finished products.
(4) The transverse area of steel pipe is more complex.
(5) Steel pipe performance is superior, metal is relatively dense.
(6) High precision and good surface quality of cold drawing finished products.
(7) The transverse area of steel pipe is more complex.
(8) Steel pipe performance is superior, metal is relatively dense.
Chinese Precision Steel Pipe manufacturer Provide high quality Chinese Precision Steel Pipe.
3. Differences between precision steel pipe and seamless steel pipe
1, seamless steel pipe is characterized by no welding joints, can withstand large pressure. The product can be very rough cast or cold pick.
2, precision steel pipe is a modern product, mainly the inner hole, the outer wall size has strict tolerance and roughness.
4. What is hot rolled precision steel pipe
Hot rolled precision steel tubes are made of continuous casting circular tube slab or first rolled slab, heated by a stepping furnace, descaled by high pressure water, and then entered into roughing mill. The roughing material is cut head, tail, and then entered into finishing mill for computer-controlled rolling. After the final rolling, it passes through laminar cooling and coiling machine to become straight coil. The head and tail of straight hair roll are often tongue and fish tail, the thickness and width accuracy are poor, and the edge often has wave shape, hem, tower shape and other defects. The coil weight is heavier and the inner diameter of the steel coil is 760mm. After finishing the straight hair coil by cutting the head, cutting the tail, cutting the edge, straightening and leveling several times, then cutting the plate or rewinding, it becomes: hot rolled steel plate, flat hot rolled steel coil, slitting strip and other products. The hot rolled pickling plate roll is formed after removing the oxide skin by pickling and applying oil.
5. Precision steel pipe applications
The use of precision steel pipe is very wide, mainly used in electric vehicles, automobiles, motorcycles, aerospace, shipbuilding, petrochemical, electric power, bearings, pneumatic components, medium and low pressure boiler seamless steel pipe and other fields, of course, in addition to these fields, precision steel pipe can also be used in hydraulic, steel sleeve, mechanical processing and other fields.
6. Comparison of domestic and foreign implementation standards
National standard: GB/T 3639-2009 Standard specification for implementation of cold drawn or cold rolled precision seamless steel tubes.
European Standard: EN 10305-1 Standard specification for precision steel tubes and seamless cold drawn steel tubes.
The German standard; DIN 2445-2 Code of practice for cold rolled precision steel pipe products.
