What is precision rolled pipe？

Precision rolled pipe is a higher-grade seamless steel pipe product with the characteristics of high precision and high surface finish requirements. In particular, the quality requirements of seamless steel pipes for oil cylinders are higher than other varieties. Most manufacturers adopt the production technology of two-roller cold rolling mill and three-roller cold rolling mill. Based on the existing equipment conditions, the steel pipe factory provides finished rolled pipe blanks through cold drawing method and finds out a more reasonable production process.

Features of finishing

1. Cold-rolled precision steel pipes have high tolerance and dimensional accuracy, product accuracy is controlled at ±0.05mm, the inner and outer walls have good finish, and there is no oxide layer on the surface.

2. Cold-rolled precision steel pipes have excellent comprehensive properties and can withstand high pressure, cold bending, flaring, and flattening without cracking or wrinkling, and can be subjected to various complex deformations and mechanical processing.

3. The promotion and application of precision seamless pipes can save steel, improve processing efficiency, reduce investment in processing procedures and equipment, save costs and greatly save processing hours, increase production capacity and material utilization, improve product quality and reduce costs.

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.
