FLEXWELL® Safety Pipe System description The FLEXWELL® Safety Pipe is a: - double-walled, monitorable, flexible and factory produced pipe system with all necessary quality tests - approved for the transport of water-hazardous, flammable or otherwise dangerous fluids - recognized and approved leak detection system - DIBt Approval Number: Z- 38.4 - 253 Leak monitoring The surveillance space between the inner and outer pipe enables permanent leak monitoring using approved leak detection devices operating either on the positive pressure or vacuum principle. The use of these systems is compliant...

FLEXWELL® Safety Pipe System description Leak monitoring The FLEXWELL® Safety Pipe is permanently monitored using pneuma- tic leak detection devices/leak detectors. These regulate the monito- ring pressure in the surveillance space and register any changes of pressure which may occur. The surveillance space is either filled with an inert gas or evacuated and prevents the uncontrolled escape of the transport medium into the environment in the event of a leakage. The surveillance space must be constructed in such a way that the proper functioning and operating safety of the leak detection...
