FIELD: heating.
SUBSTANCE: invention relates to the field of design of pipelines providing the minimal possible heat losses, both for heating and water-supply systems (hot and cold) in buildings and structures, and for direct distribution within rooms, particularly, for a channel-free distribution system built into panels or walls. Thermal-insulated pipe for heating and/or water-supply systems of building and structures consists of internal layer, forming a cylinder channel and made of polyethylene of improved heat resistance, one or two layers of cross-linked polyethylene foam or heat-resistant foamed rubber resin, covering the internal layer, and a shell covering those layers and made of one to three layers of nonlinked polyethylene foam.
EFFECT: enhancement of equipment efficiency; ensuring the reliability and service life of thermal-insulated head pipe.
