Precision Seamless cold-drawn steel pipes

Cold drawn precision steel tube is a high-precision steel tube manufactured by cold drawing process, which has superior dimensional accuracy and surface quality. Here are some key features and application areas of cold drawn precision steel tube:

Manufacturing process: The manufacturing process of cold drawn precision steel tube is carried out at room temperature, by cold drawing solid round steel rods or hollow tubes for multiple times to achieve the required dimensional accuracy and surface finish.

Dimensional accuracy: Due to the stretching and extrusion during the cold drawing process, the dimensional control of cold drawn precision steel tube is very strict, and can achieve very high precision requirements, usually within a few microns.

Surface quality: The surface finish of cold drawn precision steel tube is very high, usually does not require subsequent surface treatment, and can be directly used in high-demand application areas.

Material selection: Commonly used materials include carbon steel, alloy steel, stainless steel, etc. Cold drawn precision steel tubes of different materials can be selected according to the specific use environment and requirements.

Application areas: Cold drawn precision steel tubes are widely used in automobile manufacturing, aerospace, machinery manufacturing, electronic equipment, petrochemical and other industries. In these fields, cold-drawn precision steel tubes are usually used to manufacture high-precision and high-demand components and equipment such as bearings, automobile transmission shafts, hydraulic cylinders, and precision instruments.

Womic Steel produced Precision Seamless cold-drawn steel pipes tubes.

Usage of the precision steel tubes:

Pipeline Transport, Boiler Pipe, Hydraulic/Automobile Pipe, Oil/Gas Drilling, Machinery Industry, Chemical Industry, Mining, Construction & Decoration, Special Purpose

Advantages: Compared with hot-rolled or hot-extruded steel tubes, cold-drawn precision steel tubes have the advantages of good dimensional stability, high internal and external surface finish, and excellent mechanical properties, which can improve the wear resistance, corrosion resistance and service life of the product.

In short, cold-drawn precision steel tubes play an important role in modern manufacturing with their high precision, excellent surface quality and wide application fields, providing reliable solutions and efficient material selection for various engineering projects.
