摘要

The fire service-pressure hose (11) has a hose body (14) including an inner impermeable leak-proof layer (15) for to be transported media e.g. water, and a rigid layer (16) enveloping the leak-proof layer for receiving pressure. The hose body has an outer heat protection layer (17) and a spacer layer (18) between the rigid layer and the leak-proof layer for retaining the rigid layer and the leak-proof layer at a distance from each other. The heat protection layer and the spacer layer are attached using an adhesive. The spacer layer is made of canvas, knitted fabric, fiber glass or fibrous web.
