Scope
Main technical content: This document specifies the technical requirements, test methods, inspection rules, and marking for prefabricated insulation systems for heating engineering using ductile cast iron pipes. This document is applicable to insulation processes such as pipe-in-pipe or spray-wrapping methods, with the insulation layer made of rigid polyurethane foam and the outer protective layer made of high-density polyethylene resin. It is used in direct burial, pipe galleries, or other non-outdoor environments for heating engineering using ductile cast iron pipes, with a design temperature of no more than 130°C for water transmission.
