PPBE is a technological innovation used to protect polyethylene gas connections. Developed by Rice, GRTgaz’s Research and Development and Innovation entity, in collaboration with GRDF. This very compact device is inserted from the cabinet near the plug-in, in charge and without digging. It allows the gas to be cut off in case of excess flow. The PBOE thus addresses a dual challenge of both safety and sustainable development as it limits accidental methane emissions from a tearing of the buried gas pipeline.
