ABSTRACT:
The protective device against an overheating, in particular by fire, of individual or batteries of pressure vessels (10) of a length (1) of at least 1.5 m serves for the storage and/or transportation of high- pressure gases. The pressure vessels (10) have at least one end cap (14) with a valve (18) or an end plug (20) with a melting plug (22) of an alloy melting at a low temperature. On at least one end cap (14) a pressure pipe (24), communicating constantly with the interior of a pressure vessel (10) branches off, which pressure pipe is led in axial direction (A) along at least a part of the pressure vessel (10). At intervals (a), essentially T-shaped fittings (26) are installed in the pressure pipe (24), which fittings have in their branching-off leg a melting plug (22) of an alloy melting at a low temperature. A blindly ending pressure pipe (24) is closed off by such a melting plug (22). The protective device is primarily used on pressure vessels of aluminium, in particular with a fibre-reinforced jacketing (12).
