GB/T6479 20 Seamless Steel Pipes For High-Pressure Chemical Fertilizer Equipements

Product Description: GB/T6479 20 Seamless Steel Pipes are high-quality seamless pipes designed for use in high-pressure chemical fertilizer equipment. These pipes are manufactured in accordance with the Chinese national standard GB/T6479, which specifies the technical requirements for seamless steel pipes suitable for high-pressure applications. The 20 grade refers to a low carbon steel with a carbon content of approximately 0.20%, which provides a balance of strength and ductility.

Advantages:

Seamless Construction: The seamless design ensures no welds, reducing the risk of leaks and increasing the reliability of the pipes in high-pressure environments.
High-Pressure Resistance: These pipes are engineered to handle the pressures associated with chemical fertilizer production processes.
Chemical Compatibility: The 20 grade steel offers good resistance to the corrosive effects of various chemicals used in fertilizer manufacturing.
Dimensional Accuracy: Precision manufacturing ensures that the pipes meet stringent dimensional standards for consistent quality and performance.
Cost-Effective: Compared to higher alloy steels, the 20 grade provides a cost-effective solution for high-pressure applications without compromising on safety and performance.
