摘要

An insulating hose (1) for a pipe (2) has fleece layers (3, 4) of plastic fibers. The density of the outer layer is at most equal to half the density of the inner layer (4). The specific weight of the inner layer (of thickness 2-7 mm) is 300-500 g/m. The specific weight of the outer layer (of thickness 4-40 mm) is 100-1000 g/m.
