MULTILAYER PIPE FOR AN AIR CONDITIONING SYSTEM OF A MOTOR VEHICLE

A pipe is for an air conditioning system of a motor vehicle. The pipe includes an inner tube, located in a radially internal position, and configured to carry a fluid to be transported. The inner tube is made of one of the following materials: PA6/66, PA66, PA6T/66, PA6T/6, or EX1. An outer tube is located in a radially external position. The outer tube is made of polyamide having, in the repeating units of its macromolecules, a ratio between the number of CH2 methylene groups and the number of CONH amide groups greater than or equal to 8. EX1 is a reactive thermoplastic composition, including a continuous phase of at least one thermoplastic polymer, and in which a discontinuous phase is dispersed which is based on at least one reactive reinforcing chemical agent.
