Cold-rolled precision steel pipes have high tolerance and dimensional accuracy, product accuracy is controlled within ±5mm, the inner and outer walls have good finish, and there is no oxide layer on the surface. ±5mm is the hot rolling size requirement, and the description is very unprofessional and does not refer to wall thickness or outer diameter. The dimensions of cold-rolled precision tubes are: the outer diameter of conventional products is ±0.05mm, and the wall thickness tolerance is ±0.1mm. Special industries require precision tubes to reach the μm level, such as aerospace engine parts, medical equipment, etc.
Features of precision rolled steel pipe:
1. Cold-rolled precision steel pipes have high tolerance and dimensional accuracy, and the product accuracy is controlled at ±0.5mm. The inner and outer walls have good smoothness and no oxide layer on the surface.
2. Cold-rolled precision steel pipes have excellent comprehensive properties, can withstand high pressure, are cold-bent, expanded, and flattened without cracking or wrinkling, and can be used for various complex deformations 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, increase production volume and material utilization, and at the same time help improve product quality and reduce costs. cost.
Uses of precision rolled steel pipes:
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.
Calculation formula for the weight of finished rolled pipe: [(outer diameter-wall thickness)*wall thickness]*0.02466=kg/meter (weight per meter)
