Reorganization of ptc 2020 because of COVID-19 and announcement of the 1st Virtual Pipeline Summit (latest update: 3 June 2020)
Requirements for pipeline leak detection systems increase continuously. In Germany the operation of leak detection systems is regulated by the TRFL (Technische Regel für Fernleitungen). Even though it is a national standard, it has international acceptance as for example API1175 recommendations follow the TRFL. In May 2017 an updated version of the TRFL has been issued.
This presentation describes the differences between the TRFL 2011 and the new version regarding leak detection. The added and the classic leak detection methods are presented and their technical capabilities and limitations are described. Each method is sorted into the context of appendix VIII of the current TRFL. Finally it will be shown how all leak detection requirements of the new TRFL can be achieved by one single system showing a practical implementation in a real-world example.
