Cold-drawn seamless steel pipe is a cold-drawn seamless pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.
Cold drawn seamless steel pipe weight calculation formula: (outer diameter - wall thickness) * wall thickness * 0.02466 = kg/m (weight per meter)

The difference between cold drawn seamless steel pipe and hot rolled seamless steel pipe

The precision of cold-drawn seamless steel pipe is better than that of hot-rolled seamless steel pipe. The general precision of cold-drawn seamless steel pipe is about 20 wires, while the precision of hot-rolled seamless steel pipe is about 100 wires.

The difference between cold drawn seamless steel pipe and ordinary seamless steel pipe:

1. The main feature of ordinary seamless steel pipes is that they have no welded seams and can withstand greater pressure. Products can be very rough as cast or cold drawn.
2. Cold-drawn seamless steel pipe is a product that has appeared in recent years, mainly because the inner hole and outer wall have strict tolerances and roughness.

Features of cold drawn seamless steel pipe:

1. Smaller outer diameter.
2. High precision can do small batch production
3. The finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complicated.
5. The performance of the steel pipe is superior, and the metal is denser.
