1. Technical requirements

The GB/T 9115.1-2010 standard provides clear specifications for the strength, hardness, dimensions, and leakproofness of aluminum flange products. It requires that the products must meet the relevant technical requirements of national standards to ensure their service life and safety.

2. Dimensions

The standard provides detailed specifications for the dimensions of aluminum flange products, including requirements for nominal pressure, connection type, outer diameter, screw hole diameter, and other aspects.

3. Material

The standard stipulates that the aluminum alloy materials used for aluminum flanges should comply with relevant standards, such as those for aluminum alloys used in steel structures and aviation applications.

4. Seal

The standard requires that products must use seals that comply with national or industry standards to ensure their sealing performance and service life.

In summary, the formulation and implementation of national standards for aluminum flanges play a crucial role in ensuring product quality and promoting the healthy development of the industry. Looking ahead, with further technological advancements, the national standards for aluminum flanges will continue to be updated and refined to better cater to the needs of various industries.
