How is high precision cold drawn seamless tube produced?

A seamless steel tube with high precision, known as high-precision cold-drawn tube, is manufactured through the process of cold-rolling, cold-drawing or a combination of both. It is renowned for its exceptional dimensional accuracy and superior surface finish, making it a popular choice for hydraulic cylinder tube.

Our company is a professional manufacturer of honed tubes and CDS tubes,Let us present the production process for high-precision cold-drawn tubes:

(1) The supply of pipe materials, which can be hot-rolled finished pipes or semi-finished pipes, extruded pipes, and welded pipes.

(2) Preparation of pipe materials, involving inspection, bundling, pickling, cleaning, rinsing, neutralization, drying, lubrication, and more.

(3) Cold rolling or cold drawing.

(4) The finishing of the final products, which includes heat treatment, straightening, sampling, cutting the head and tail, inspection, hydraulic testing, oiling, packaging, storage, and other procedures. The finishing contents vary depending on the product.

The utilization of high-precision cold-drawn steel pipe is highly recommended for hydraulic cylinder tubes due to its exceptional metal properties. The primary component of a hydraulic cylinder barrel is the hydraulic cylinder tube, which is made from this type of steel. The high-precision cold-drawn steel tube used in creating hydraulic cylinder tubes offers superior strength, rigidity, wear resistance, and performance. Additionally, the inner surface is hard, while the outer surface is tough.

Cold-drawn seamless tubes with high precision are applicable in a variety of industries, including hydraulic system and automobile manufacturing piping, military and construction machinery, railway locomotives, aerospace, ships, injection molding and die-casting machines, machine tools, diesel engines, petrochemicals, power plants, boiler equipment, and more.
