Both metal expansion joints and non-metal expansion joints have specific execution standards in their respective application fields.
For metal expansion joints, the main execution standards include two national standards: Steel Metal Expansion Joints (GB/T 12777-2008) and NonSteel Metal Expansion Joints (GB/T 12779-2008). Among them, GB/T 12777-2008 is applicable to the design, manufacturing, and acceptance of steel metal expansion joints, while GB/T 12779-2008 is applicable to the design, manufacturing, and acceptance of non steel metal expansion joints. Inaddition, according to the needs of different industries, there are also some industry standards, such as the "Design Specification for Metal Expansion Joints" (SY/T 0510-2017) in the petrochemical industry and the "Technical Conditions for Metal Expansion Joints in Nuclear Power Plants" (HAF604-1985) in the nuclear power industry.
For non-metallic expansion joints, the main execution standard is JB/T12235-2015. This standard specifies the definition, product classification and marking, requirements, test methods, inspection rules, as well as the content of marking, packaging, transportation, and storage of non-metallic expansion joints.
Please note that the above are only some of the main execution standards for metal expansion joints and non-metal expansion joints, and the specific standards may vary depending on product types, application areas, and regional differences. Therefore, in practical applications, it is necessary to determine and comply with corresponding execution standards based on specific products and usage scenarios. Meanwhile, with the advancement of technology and the updating of standards, it is recommended to consult the latest standard documents in practical applications to ensure product compliance and safety.
