Abstract: A corrosion-resistant and fire-resistant pipe system suitable for sprinkler systems and the like in the offshore industry and also on military and civilian seagoing vessels, and generally as sprinkler systems in official buildings and in industrial buildings. The pipe system is characterized in that the pipe system includes rigid and cold-formable pipe sections (10) that have one or more tubular rubber layers (11, 13, 15) and reinforcement layers (12, 14) that surround or embrace one or more of the tubular rubber layers (11, 13, 15). The reinforcement layers are comprised of wires or ribbons that have been wound, braided, knitted or formed in some other way so as to cross each other, wherein each of the wires or ribbons defines with the longitudinal axis of the pipe section a winding or spiraling angle that imparts the greatest possible strength to the reinforced, tubular rubber layers (11, 13, 15).

Abstract: A pipe or hose (10) intended primarily for fire protection purposes and capable of withstanding high heat flux densities. The pipe or the hose has an internal, tubular rubber layer (11) and a casing (12) provided with holes which casing embraces the tubular rubber layer (11) in close contact therewith. The holes in the casing (12) are situated close together and have a limited cross-sectional area such that liquid transported in the pipe or hose (10) at a current liquid pressure above atmospheric pressure and through the medium of a nozzle effect in direct contact with the casing (12) and, subsequent to release from said casing contact, is able to form a free-standing liquid jet. When used in sprinkler systems or like fire extinguishing systems, the pipe or the hose will be imparted herewith self-sealing and self-protecting properties, and will withstand a heat flux density caused by a jet fire of up to about 500 kW/m.sup.

Abstract: A fire safety coating, particularly intended for application to hydrocarbon-conducting steel pipes (1) in the splash zone underneath oil plants at sea, consists of at least three layers, where the outer layer (5) is a mechanical protecting layer of rubber or plastic material, the next inside layer (4) is a flame-stopping layer comprising inorganic fibers and a rubber material, and an inside layer (3) is a rubber material which reacts particularly at a high temperature to liberate gases which both prevent inward penetration of oxygen and cause a transformation of the rubber material in the flame-stopping layer (4) to form a hard shell.
