GB/T 17116.3-1997

This standard specifies the dimensions, materials, and technical requirements for middle connection attachments and building structure attachments used in pipe support and hanger assemblies. It is applied in industrial and civil piping systems to ensure proper load transfer from pipes to building structures, particularly in power plants, petrochemical facilities, and HVAC installations. The standard provides design and procurement specifications for components like pipe clamps, beam clamps, and weldable attachments that connect piping to steel beams or concrete structures.
