Cold drawn tube

The precision cold drawn tube has good appearance quality, smooth and clean inside and outside, which reduces the processing links of surface rust in the early stage of the general seamless tube processing. The precision size can greatly reduce the processing volume of the workpiece, improve the utilization rate of the material, and make up for the general lack of Large deviation of the seam pipe size and low utilization rate. In this way, it not only reduces the cost for the production enterprise, increases the output, and improves the competitiveness of the production enterprise.
