Abstract
A pipe intended to be mounted in a fluid circuit of an aircraft, the pipe comprising a tube and two connection ends, the tube being made of a thermoplastic material and having a cylindrical shape, the tube defining an internal surface, intended to be in contact with the fluid, and an external surface opposite the internal surface, the pipe comprising at least one reinforcement band extending longitudinally on the external surface of a longitudinal portion of the tube, so as to form a reinforced portion of the tube.

A method of manufacturing a pipe intended to be mounted in a fluid circuit of an aircraft, the pipe comprising a tube and two connection ends, the tube being made of thermoplastic material and having a cylindrical shape, the tube defining an internal surface, intended to be in contact with the fluid, and an external surface opposite the internal surface, the manufacturing method, comprising:
- a step of determining at least two portions to be reinforced of the tube,
- a step of determining at least one portion to be bent, the portion to be bent being positioned between the at least two portions to be reinforced,
- a step of positioning at least one reinforcement band extending longitudinally over the external surface of the at least two portions to be reinforced, the portion to be bent being free of the reinforcement band, then
- a step of bending the portion to be bent.
A method of manufacturing a pipe for use on an aircraft, the pipe comprising a thermoplastic cylindrical tube section having two connection ends, the tube section having an internal surface and an external surface opposite the internal surface, the manufacturing method, comprising:
- positioning one or more reinforcement bands over the external surface of the tube section at two spaced apart portions of the tube section to define two spaced apart portions of the tube section to be reinforced in a positioning step;
- bending a portion of the tube section at a location between the two spaced apart portions of the tube section to be reinforced to define a bent section in a bending step;
- and
- wherein the bent section is free of the one or more reinforcement bands and is formed after the positioning step.
