Advanced cold drawing processing technology is used in the manufacturing process of precision cold drawn steel pipes, which makes it have the advantages of high precision, high smoothness, high strength, etc., and is widely used in various high-demand occasions. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and at the same time help improve product quality.
Common specifications of cold drawn steel pipes: 12mm 14mm 18mm 20mm 25mm 28mm 30mm 32mm 35mm 38mm 40mm 42mm 52mm.
High-quality carbon structural steel cold-drawn seamless pipes are mainly made of No. 10 and No. 20 steel. In addition to ensuring the chemical composition and mechanical properties, hydrostatic tests, curling, flaring, flattening and other tests are required.
