Cold Rolled Precision Steel Pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because there is no oxide layer on the inner and outer walls of the precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation after cold bending, no flaring, no cracks in flattening, etc.
Application
Cold Rolled Precision Steel Pipe are widely used in Automobiles, Motorcycles, Electric Vehicles, Petrochemicals, electric power, ships, Aerospace, Bearings, Pneumatic Components, Medium and Low Pressure Boiler pipe, Steel Sleeves, Bearings, Hydraulics, Machining and other fields.
Product Feature
1. The outer diameter is smaller.
2. High precision and small batch production.
3. The cold drawn finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complicated.
5. The performance of the steel pipe is better and the metal is denser.
Process
Tube blank - inspection - peeling - inspection - heating - perforation - pickling and passivation - grinding - lubrication and air drying - cold rolling - degreasing - cutting head - inspection - marking - Product packaging.
Delivery Conditions
BKS(+SR): After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
NBK(+N): After the final cold drawing operation the tubes are normalized in a controlled atmosphere.
GBK(+A): After the final cold drawing process the tubes are annealed in a controlled atmosphere.
BK(+C): No heat treatment after the final cold drawig process.
BKW(+LC): After the final heat treatment there is a suitable drawing pass.
Packing & Delivery
Main standards: DIN2391, DIN2445, EN10305, DIN1629, DIN1630, ASTM A179.
