FLEXWELL® Safety Pipe System description Construction and function 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 - Dimensions: DN 12 – DN 100 - Pressure range: 25 bar, PN 25 - Temperature range: –10 °C and +50 °C - DIBt Approval Number: Z – 38.4 - 253 Construction of the FLEXWELL® Safety Pipe: Leak monitoring 1 corrugated inner pipe (1.4404/1.4571) 2 surveillance...

FLEXWELL® Safety Pipe The FLEXWELL® Safety Pipe is permanently monitored using pneumatic leak detection devices/leak detectors. These regulate the monitoring pressure in the surveillance space and register any changes of pressure which may occur. The surveillance space 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 system is ensured under all operating conditions. In the case of a leakage the alarm is given...
