Precision cold drawn pipe has the characteristics of high precision, high finish, good inner wall cleanliness, high pressure without leakage, cold bending without deformation, flaring, flattening without cracks, etc. It can be used for various complex deformation and mechanical processing. The chemical composition of precision cold drawn pipe is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.

Main uses: for automobiles, motorcycles, refrigeration equipment, hydraulic parts, bearings, pneumatic cylinders, and other customers who have high requirements for steel pipe accuracy, smoothness, cleanliness, and mechanical properties.

Seamless steel pipes are perforated from a whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have square, oval, triangular, hexagonal, melon seed, star, and finned pipes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
