Product Description

Cold-rolled precision seamless steel pipe is a kind of seamless steel pipe with high dimensional accuracy and good surface finish for precision mechanical structures, hydraulic equipment or steel sleeves.

High-precision cold-drawn precision steel pipe is a new type of steel pipe, its main feature is high precision. There are usually two production processes: two-roll mill and three-roll mill. The precision of cold-rolled seamless steel pipe produced by three-roll mill is higher and can be controlled within a few wires, but the price is relatively higher.

The promotion and application of high-precision cold-drawn precision steel pipes can save steel, improve processing efficiency, and save energy. Good, it can greatly save machining time, improve material utilization, and at the same time help improve product quality.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless steel thin-walled steel pipes, etc. Wall steel pipe, special-shaped steel pipe.
