Abstract
The invention relates to the assembly of a tube (1) made from composite material and a tubular metal part (2) in order to produce pipes. The assembly process comprises:—inserting a portion of the metal part (2) into the composite material tube (1); and—radially deforming the metal part (2) to a plastic deformation range sufficient to cause elastic deformation of said composite material tube (1), in order to obtain a radial contact between the outer wall of the metal part (2) and the inner wall of the composite material tube (1).
Claims16
A method of assembling a tube made from composite material and a tubular metal part, comprising:
- inserting a portion of said metal part into said tube made from composite material,
- radially deforming said metal part up to a plastic deformation range sufficient to cause elastic deformation of said tube made from composite material in order to obtain radial contact between the external wall of the metal part and the internal wall of said tube made from composite material.
An assembly, comprising a tube made from composite material and a tubular metal part, wherein a portion of said metal part is inserted in said tube made from composite material, and said metal part has been radially deformed up to a plastic deformation range sufficient to cause elastic deformation of said tube made from composite material in order to obtain radial contact between the external wall of the metal part and the internal wall of said tube made from composite material.
A pipe, comprising a first assembly and at least one second assembly connected to said first assembly,
- wherein each of the first and second assemblies has a respective tube made from composite material and a respective tubular metal part, wherein a portion of said metal part is inserted in said tube made from composite material, and said metal part has been radially deformed up to a plastic deformation range sufficient to cause elastic deformation of said tube made from composite material in order to obtain radial contact between the external wall of the metal part and the internal wall of said tube made from composite material.
