ABSTRACT:
A crack indicator based on a piping system consisting of cold-embrittling plastics pipes imbedded in a gas container insulation. A warning gas is subjected to an excess pressure in the piping system. In the event of a crack or other damage to the insulating material, a leak is produced in the piping system at this point so that warning gas flows out into the tank interior. In this case, an indicator responding to the issuing warning gas produces an alarm signal. The alarm emitter can consist, for example, of an analysis instrument for the specific gas. However, an indicator based on a pressure measuring system which is connected upstream of the piping system and produces an alarm signal when a predetermined pressure difference is exceeded is simpler.
