1. Thin tube drawing: Thin tube drawing is a seamless steel tube manufactured by drawing process. In this process, the steel billet after pickling passes through the die under specific conditions, and the pipe is gradually stretched under the pulling force to form the pipe with the required diameter and wall thickness. Precision tube drawing has high dimensional accuracy and smooth inner and outer surfaces, and is widely used in automobile manufacturing, mechanical equipment and precision instruments.
2. Cold-drawn pipe: Cold-drawn pipe is also a kind of seamless steel pipe, but its manufacturing process is slightly different from that of precision drawn pipe. Cold-drawn pipe adopts cold-drawn process, and the steel billet after pickling passes through the die at room temperature and is gradually elongated and thinned under the action of cold-drawn force to form seamless pipe. Cold-drawn tubes have high dimensional accuracy and flatness, and are mainly used to manufacture high-precision mechanical parts, hydraulic equipment and precision instruments.
3. Precision tube: Precision tube is a highly precise metal tube with high dimensional accuracy and smoothness. It is usually made by cold drawing process, using high-quality raw materials, and processed through multiple processes in the manufacturing process. Precision tubes are widely used in automobile manufacturing, aerospace, electronic equipment and chemical industry to transport liquids, gases and solids.
4. Cold-tied pipe: Cold-tied pipe refers to a metal pipe manufactured by binding process at room temperature. In this process, the blank is extruded and deformed by pressure in the mold, thus gradually becoming the required tubular shape. Cold-tied pipes are widely used in construction, bridge, machinery, petrochemical and other industries because of their simple manufacturing process and relatively low cost.
5. hot tube: hot tube is a metal tube, which is made by extrusion process at high temperature. In the process of thermal bonding, the blank is heated to a certain temperature, and then extruded into the required tube shape under the pressure of the bonding roller group. Hot tube's manufacturing technology is simple and efficient, and it is widely used in construction, machinery manufacturing, petrochemical industry, energy and other fields.
To sum up, seamless steel pipe is a precision drawn pipe made by drawing process, cold drawn pipe is made by cold drawing process, and precision pipe is a high-precision metal pipe. Cold-tied pipe and hot-tied pipe refer to metal pipes manufactured by binding at room temperature or extruding at high temperature respectively. They are different in dimensional accuracy, processing technology and application fields. These pipes have important application value in their respective fields and meet the requirements of different industries for the quality and performance of pipes.
