  • Composite strip, and methods for forming a junction between two conduits
    Patent number: 10907754
    Abstract: A composite strip which extends in a main direction between first and second ends and which comprises a main strip comprising first fibres embedded in a matrix. The first fibres are made of carbon, an electrically conducting material, and the matrix is made up of at least one polymer. The composite strip further comprises a junction layer formed of an electrically conducting junction material. The junction layer is placed on the main strip.

  • Method for forming an electrical connection
    Patent number: 10283925
    Abstract: A method for forming an electrical connection in a pipe for transporting a fluid. The pipe comprises an internal hollow tube and a heating layer comprising first fibers made of carbon. There are performed a groove-formation step in which a groove is formed in the heating layer, an interface-preparation step in which a junction layer is placed on the heating layer of the groove, and a placement step in which a connection strip comprising second fibers formed of a second electrically conducting material is wound on the junction layer.
