<p>A fire safety coating, particularly intended to be used on hydrocarbon-conducting steel piping (1) in the splash zone beneath oil plants at sea, consist of at least four layers, where the outer layer (5) is a mechanical protection layer of rubber or plastic, the next inside layer (4) is a flame-stopping inorganic fibre layer, an intermediate layer (3) is a rubber material which reacts in a special manner at high temperatures to liberate gases which both prevent inward penetration of oxygen and cause transformation of the outer layers (4, 5) to a hard shell, and the innermost layer (2) is a corrosion inhibiting and possibly thermally insulating layer, preferably of rubber of plastic.</p> |
