The main product application characteristics of the finishing pipe

Finishing-rolled pipe is one of the higher-grade varieties of seamless steel pipe products. It has the characteristics of high precision and surface finish requirements, especially the quality requirements of seamless steel pipes for oil cylinders are higher than other varieties. There are very few domestic manufacturers that use cold drawn tubes as finishing tube blanks. Most manufacturers use the production process of two-roll cold rolling mill for blanking and three-roll cold rolling mill for finishing. According to the existing equipment conditions, the steel pipe factory provides tube blanks for finishing tubes by cold drawing, and has explored a more reasonable production process. Its products, as finishing tube blanks, can produce high-quality seamless steel pipes for oil cylinders .

The characteristics of the finishing pipe:

1. The cold-rolled precision steel pipe has high tolerance and dimensional accuracy, the product accuracy is controlled within ±0.05mm, the inner and outer walls are smooth, and the surface has no oxide layer.

2. The comprehensive performance of cold-rolled precision steel pipe is excellent, it can withstand high pressure, cold bending, flaring, flattening does not crack, does not wrinkle skin, and can do various complex deformation and mechanical processing.

3. The promotion and application of precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save machining hours, improve production and material utilization, and at the same time help improve product quality and reduce costs. 

The use of finishing pipe:

Cold-rolled precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, medium and low pressure boilers and other fields.
