Production Process

1. Raw Material Preparation: The first step in producing hot-dip galvanized seamless steel pipes is selecting high-quality carbon structural steel, such as Q235 or Q345. These materials offer good weldability and mechanical properties.

2. Pipe Blank Manufacturing: Using continuous rolling or forging methods, the raw material is processed into pipe blanks. This process ensures the density and uniformity of the pipe blanks.

3. Heat Treatment: The pipe blanks undergo heating and homogenization to eliminate internal stresses and enhance the mechanical properties of the material.

4. Seamless Pipe Forming: A piercing machine is used to perforate the heated pipe blank, forming the seamless pipe shape. Control of temperature and pressure during this process is crucial to ensure uniform wall thickness.

5. Galvanizing Treatment: After the seamless steel pipe is completed, it is immersed in molten zinc for hot-dip galvanizing. This process effectively improves the pipe's corrosion resistance and extends its service life.

6. Inspection and Packaging: Finally, each steel pipe undergoes rigorous quality testing to ensure it meets standards before packaging and shipping.


Application Fields

1. Construction Industry: Hot-dip galvanized seamless steel pipes are widely used in building structures, brackets, and piping systems, providing stable and durable solutions.

2. Oil and Gas: In the oil and gas industry, these pipes are used for transporting media, as their high-pressure and corrosion-resistant properties effectively prevent leaks.

3. Chemical Industry: Due to their corrosion resistance, hot-dip galvanized seamless steel pipes are commonly used in chemical equipment and storage tanks, ensuring safety and durability.

4. Agricultural Irrigation: In agriculture, hot-dip galvanized pipes are used for constructing irrigation systems, improving efficiency and reducing maintenance costs.
