Cold Rolled Seamless Steel Pipe

Cold-drawn precision seamless steel pipe is a high-precision steel pipe material. The main categories are: precision seamless steel pipe, precision hydraulic seamless steel pipe, cold-drawn precision seamless steel pipe, cold-rolled precision seamless steel pipe, high-precision seamless steel pipe, precision bright seamless steel pipe.

Advantage
1. The surface finish of the pipe in the precision pipe is high, and the surface of the steel pipe will not produce an oxide film after heat treatment, and it is not easy to deform during cold bending.

2. Can withstand high-strength pressure.
3. In the field of machining, the utilization rate of precision tubes is also very high.

Compared with seamless steel pipes, the process of manufacturing precision pipes is relatively complicated. From the completion of each process, the necessary inspections are required to ensure that the precision tubes are of higher quality and longer service life when they leave the factory.

Application

Precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc.

Production Process

Different processing methods and corresponding auxiliary procedures are selected according to the processing performance of the metal, the size of the pipe, the quality requirements, and the investment and benefits. The basic processes of cold-rolled and cold-drawn pipes are:

(1) pipe material supply, the pipe materials used are hot-rolled finished pipes or semi-finished pipes, extruded pipes and welded pipes;

(2) pipe material preparation, including inspection, bundling, acid Washing, cleaning, rinsing, neutralizing, drying, lubricating, etc.;

(3) Cold working (cold rolling or cold drawing);

(4) Finishing of finished products includes heat treatment of finished products, straightening, sampling, cutting heads and tails, inspection (Manual inspection and various flaw detection), hydraulic test, oiling, packaging, storage, etc. Different products have different finishing contents.
