    APPENDIX W VACUUM LEAK DETECTOR VL .. Using the VL .. underpressure leak detector on tanks which have been allowed to warm up The following example applications are described in this appendix: W.1: Tank for storing liquids which are viscous or have a tendency to solidify at ambient tem- perature (temperatures >50°C and <150°C), and where a sufficient length of the measu- ring line has been routed inside the tank insulation, or for tanks used to store liquids which remain thin at ambient temperature.
  • Page 42 APPENDIX W VACUUM LEAK DETECTOR VL .. (2) Selection of the lines connecting the mounting set and the leak detector. Use of metal pipes, Cu or VA pipes. Plastic pipes are not suitable. The between the leak detector and the mounting set must be at least 3 m in length. This will ensure that the warm (hot) air extracted from the interstitial space can cool down before it reaches the leak detector.
