Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for prefabricated directly buried insulating pipes that combine a plastic-steel-plastic composite inner pipe with polyurethane foam insulation and a high-density polyethylene outer casing. It is applied in the construction industry for district heating, hot water supply, and industrial pipeline systems where pipes are buried underground to reduce heat loss and protect against corrosion and mechanical damage. The standard ensures consistent quality and performance for energy-efficient, long-distance buried piping networks.
