Abstract
A heat-insulated wound hose is formed by a process, in which a metal wound hose is at first upset, such that turns, which are spaced apart by adjacent axial wall areas of individual turns, form at least one uninterrupted jacket wall surface. A ceramic-based coating is subsequently applied to the at least one uninterrupted jacket wall surface. The coating is then cured, and the wound hose thus formed is subsequently pulled apart, whereby adjacent axial wall areas of adjacent turns are detached from one another and thereby the coating is broken up at partitions.
