Abstract

A hose is formed as a spiral component hose of synthetic material, which is surrounded by a gas-tight corrugated hose of fiberglass weave coated with aluminum. The insulation for the hose consists of several sequential layers of synthetic material felts and synthetic material foils, preferably a total of three groups, each consisting of a polyester felt, an interior foil of polyethylene, and an exterior foil of polyethylene terephthalate. The outermost finish consists of a corrugated hose of synthetic material.
