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.

Standard requirement
1. Appearance of cold-rolled steel pipe
Cold-rolled steel pipes are not allowed to have any traces of cracks on the outer surface and its inner surface, even if it is very slight, and on its inner and outer surfaces, There can be no fold marks, rolling marks, delamination marks and scarring. If any of these problems appear on the surface, it is unqualified, and these marks need to be eliminated again, so as to achieve In a perfect state, the most important thing is that when cleaning these defects, the depth of cleaning has a certain limit, and the thickness it cleans cannot be greater than its allowable range.
For cold-rolled steel pipes, the cleaning value of the steel pipe cannot be greater than 4% of the nominal wall thickness, that is, if the wall thickness of the steel pipe is 1.4 mm, the allowable cleaning thickness is below 0.05 mm. not more than 0.05 mm.
2. Features and functions
The use and application of cold-rolled steel pipes can save a lot of steel, and can also improve the efficiency of production and processing of products.
The use of cold-rolled steel pipes also greatly saves a lot of energy. High-precision steel pipes can reduce processing time, improve material utilization, and improve product quality.
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.
