Introduction of GB/T 8464-2023 Iron, Copper, and Stainless Steel Threaded Connection Valves
GB/T 8464-2023 is a Chinese national standard that specifies the requirements for iron, copper, and stainless steel threaded connection valves. This standard is applicable to valves with threaded connections used in various industries, including but not limited to water supply, heating, gas supply, and oil pipelines.
The standard covers a wide range of valves, including gate valves, globe valves, ball valves, check valves, and butterfly valves. It provides guidelines for the design, materials, dimensions, performance, testing, and marking of these valves. The standard ensures that the valves meet the necessary quality and safety standards, promoting the reliability and efficiency of threaded connection valves.
One of the key aspects of this standard is the requirement for the materials used in the valves. It specifies the chemical composition, mechanical properties, and heat treatment of the iron, copper, and stainless steel materials. This ensures that the valves are resistant to corrosion, pressure, and temperature variations, guaranteeing their durability and longevity.
Additionally, the standard outlines the dimensions and tolerances for the valves, enabling easy and accurate installation and maintenance. It also includes performance requirements, such as leakage rates and operating torque, which ensure optimal functioning of the valves.
In conclusion, GB/T 8464-2023 is a comprehensive standard that sets the guidelines for the design, materials, dimensions, performance, testing, and marking of iron, copper, and stainless steel threaded connection valves. It ensures the quality, safety, and reliability of these valves, making them suitable for various industrial applications.
