Definitions
- Pipe for transporting automotive fluids comprising a smooth inner tube and a corrugated outer tube.
- the present invention relates to a pipe for transporting automotive fluids such as coolant, fuel, windshield washer fluid, etc.
- a pipe for transporting automotive fluids comprising a smooth inner tube based on a fluorinated thermoplastic material, a corrugated outer tube. Which is in contact with the inner tube through the inner top of its waves and which is made of a thermoplastic material based on polyamide, and means for connecting the outer tube to the inner tube.
- the pipe thus obtained is particularly well suited to the transport of automotive fluids and has • a good ability to be shaped, in particular by "elastic" deformation.
- This pipe is also simple and inexpensive to produce.
- the smooth interior pipe also makes it possible to produce simply connections with the organs to which the pipe is connected, for example by means of nipples integral with the members and force fitted into the inner tube.
- the tubes are monolayer
- the polyamide used is a poly 12
- the fluorinated thermoplastic is one of the materials. following rials:
- PVDF polyfluorovynylidene
- ETFE ethylene tetrafluorethylene
- EEP ethylene perfluoroethylene
- This embodiment has very good characteristics for the transport of automotive fluids.
- the pipe of the invention comprises an inner tube, generally designated at 1, and an outer tube, generally designated at 2, surrounding the inner tube 1 .
- the inner tube 1 is a smooth tube here having a monolayer structure in a fluorinated thermoplastic material.
- the fluorinated thermoplastic material used is a polyfluorovynylidene (PVDF), or a polytetrafluorethylene
- PTFE ethylene tetrafluorethylene
- ETFE ethylene tetrafluorethylene
- EFEP ethylene perfluoroethylene
- the outer tube 2 is a corrugated tube forming waves having an inner vertex 3 of inner diameter equal to or very substantially close to the outer diameter of the inner tube 1.
- the tubes 1 and 2 are connected either at each vertex 3 by gluing or by adhesion for example during a coextrusion process or, if the pipe is of determined length, at the location of its ends by simple mechanical abutment of the outer tube 2 against a flange of the inner tube 1 with or without bonding the ends of the tubes 1 and 2 to one another.
- materials are chosen which are capable of adhering or of being bonded to each other.
- the outer tube 2 here has a single-layer structure of polyamide and preferably of polyamide 12.
- the materials used can be recycled materials, for example from the grinding of scrap tubes, which causes less pollution and generates economic gain.
- the pipe is obtained here by means of a known machine which comprises an extrusion head making it possible to produce, through a first channel, a parison which is pressed under the effect of an external suction against articulated molds surrounding the head d extrusion and moving parallel to the axis thereof.
- a second extrusion channel allows, downstream of the parison extrusion, to fill the corrugated tube formed by the parison inside the molds with an internal smooth tube, which makes it possible to produce the pipe of the invention .
- a supply channel between the corrugated tube and the smooth tube, of a neutral gas which will cooperate in reducing the permeability of the pipe according to the invention.
- This neutral gas air, nitrogen or any other suitable gas, may be kept under pressure inside the waves of the corrugated tube, this pressure being able to constitute an insulating element fighting against the migration of the vapors of inside or outside through the pipe wall.
- the connection of the two tubes will be carried out niere waterproof and preferably at each interior vertex of the corrugated tube.
- the inner tube may include an internal conductive layer in order to allow the discharge of the electrostatic charges generated by the friction of the fluid transported along the pipe. This limits the risk of explosion when the transported fluid is flammable.
- the material of tube 1 will be chosen according to its chemical resistance and its permeability to the fluid conveyed, while the material of tube 2 will be chosen mainly for its characteristics of resistance to the external atmosphere, chemical resistance. and mechanical and corrosion resistance.
