FLUID TRANSFER MULTI-LAYER TUBE BASED ON A POLYAMIDE AND AN ETHYL VINYL ALCOHOL OR POLYVINYL ALCOHOL

摘要

The present invention relates to a symmetrical multi-layer tube based on polyamide and ethyl vinyl alcohol (EVOH) or polyvinyl alcohol (PVOH) for transferring fluids. As examples of tubes for transferring fluids, mention may be made of fuel (gasoline, diesel fuel) pipes, in particular for carrying fuel from the tank to the engine of motor vehicles. Other examples of fluid transfer include, but are not limited to, the fluids used in fuel cells, CO₂ systems for cooling, hydraulic systems, cooling circuits and air-conditioning circuits, and medium-pressure power transfer.
