Answer; What is the difference between cold-drawn precision seamless steel pipe and ordinary seamless steel pipe?

Cold drawn precision seamless steel tube bright precision tube? The main characteristics of precision pipe alloy pipe are: high accuracy of inner and outer walls of steel pipe, high smoothness, no oxide layer after heat treatment, high cleanliness of inner wall, high pressure resistance of steel pipe, no deformation and no crack during cold bending, flaring and flattening, and various complex deformation and machining can be carried out. Steel pipe color: white with luster and high metallic luster.

Cold-drawn precision seamless steel pipe is characterized by high tolerance dimension accuracy of cold-rolled precision steel pipe, product accuracy controlled within 5 mm, good internal and external wall smoothness and no oxide layer on the surface. Cold-rolled precision steel pipe has excellent comprehensive performance, can withstand high pressure, cold bending, flaring and flattening without cracking and wrinkling, and can do all kinds of complex deformation and machining. The popularization and application of precision seamless tube can save steel, improve processing efficiency, reduce investment in processing procedures and equipment, save costs and greatly save processing time, improve output and material utilization, and help to improve product quality and reduce costs. Application of finishing rolling pipe: Cold-rolled precision steel pipe is widely used in automobile, motorcycle, electric vehicle, petrochemical, electric power, ship, aerospace, bearings, pneumatic components, medium and low pressure boilers and other fields. The formula for calculating the weight of finished pipe is [(outside diameter-wall thickness) * wall thickness ]*0.02466=kg/ m (weight per meter
