FIELD: machine building.
SUBSTANCE: invention relates to heat insulated assembly "pipe in pipe". The insulated assembly "pipe in pipe" contains at least one internal pipe, with external surface, one container with pressed porous resilient compressed material and secured to the internal pipe, external pipe located above the container such that internal surface of the external pipe and external surface of the container are in complete or partial direct contact. The compressed porous resilient compressed material contains porous particles. Under another option the container is located in ring space created between the internal surface of the external pipe and external surface of at least one internal pipe. Under one more option the assembly additionally contains enclosure located between the container and compressed material.
EFFECT: improved method of manufacturing of insulated assemblies "pipe in pipe".
