Cold drawn seamless steel tube process

　　Cold Drawn Seamless Tubing (CDS)is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.

　　Benefits of Cold Drawn Seamless Tubing

　　Cold drawn seamless pipes are seamless steel pipes with a circular cross-section made by cold drawing . Its name refers to the shape of steel pipes, such as thick-walled cold-drawn seamless pipes, thin-walled cold-drawn seamless pipes, etc. Cold drawn seamless pipes are widely used in the production of various structural parts, tools and mechanical parts. Compared with round pipes, cold drawn seamless pipes generally have larger moments of inertia and section modulus, have greater torsion resistance, save materials, and improve efficiency. They can be directly processed without deep processing in factories or mechanical processing plants. Use, reduce workload, improve work efficiency, and be loved by terminal demand.

　　Cold drawn seamless tubing provides a better uniformed OD and ID, enhanced machinability, increased strength, and tighter tolerances compared to hot finish seamless products.

　　Superior surface finish

　　High yield strength

　　Dimensional accuracy and excellent micro-structure uniformity

　　Enhanced machinability

　　High strength to weight ratio

　　Tight tolerances, resulting in reduced machine time

　　Possible spiraling eccentricity inherent in product

　　Cold Drawn Seamless Mechanical Tubing

　　Rolling hard roll can be used as the raw material of the hot-dip galvanizing plant, hot dip galvanizing line set annealing line. Rolling hard roll weight is generally 6 to 13.5 tons, the coil diameter of 610mm

　　Cold drawn seamless pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc. It can also be applied to steel sleeves, bearings, hydraulics, etc. Mechanical processing and other fields.
