Cold-drawn seamless pipes have the following characteristics and advantages that make them play an important role in the industrial field:
1. High-quality materials: The cold-drawn seamless pipe uses high-quality steel as raw materials, with excellent physical and chemical properties. It has high strength, corrosion resistance and high temperature resistance, and can adapt to a variety of harsh working environments and conditions.
2. Seamless performance: The cold-drawn seamless pipe is manufactured through cold-drawn processing, with smooth and flat internal and external surfaces and no welding defects, ensuring the integrity and reliability of the pipeline. Compared to welded or hot-rolled pipes, cold-drawn seamless pipes have better performance under pressure and stress.
3. Accurate size: The manufacturing process of cold-drawn seamless pipes can achieve more accurate size control. Through precise mold and cold-drawing processing, it is possible to produce pipe diameters, wall thickeners and lengths that meet strict requirements, ensuring a good match between pipes and supporting equipment.

Production process:Q550D carton rectangular steel pipe
1. Material preparation: The manufacture of cold-drawn seamless tubes begins with the material selection process. High-quality steel is selected as the raw material, usually carbon steel or alloy steel with a higher carbon content. These steels have good plasticity and mechanical properties, and are suitable for cold drawing to form seamless pipes.
2. Heating treatment: The selected billet is heated to improve its plasticity and mechanical properties. The billet is heated to the appropriate temperature range, usually between 1100°C and 1250°C, in order to achieve good plasticity and deformation properties in preparation for subsequent cold drawing.
3. Cold drawing process: the heated billet is cold-drawing process. In this step, the billet is stretched through a series of molds, gradually forming the shape of a seamless tube. By drawing and extrusion, cold drawing not only changes the shape and size of the steel, but also improves its microstructure and seamless properties.
4.Heat treatment: The seamless pipe after cold drawing is heat treated to improve its mechanical properties and stability.
