The GB/T 6479 standard specifies the requirements for seamless steel pipes used in high-pressure fertilizer equipment. This standard is crucial for ensuring the safety and reliability of pipes used in the fertilizer industry, where high pressures and corrosive environments are common.
The primary materials used for the production of seamless steel pipes under this standard include various grades of carbon steel, specifically designed to withstand high pressure and corrosive conditions.
The specifications for GB/T 6479 seamless steel pipes include dimensions, tolerances, and mechanical properties. The pipes are typically available in various diameters and wall thicknesses to meet different application requirements.
