INTERMEDIATE COUPLING FOR CONNECTING RIGID-PIPE ELEMENTS FOR CONVEYING A FLUID, AND ASSOCIATED PIPE NETWORK AND ASSEMBLY METHOD

摘要

The coupling includes a rigid inner shell (60) and an electric connecting line (68A, 68B), designed to heat a fluid flowing in the inner shell (60). The coupling (10) includes a rigid outer shell (62) positioned around the inner shell (60), the outer shell (62) and the inner shell (60) delimiting an intermediate space (64) between them containing the electric line (68A, 68B) and a thermally insulating layer (66) positioned in the intermediate space (64).
