Document Type and Number:
WIPO Patent Application WO/2023/072234
Kind Code:
A1
Abstract:
A pipe system, comprising a plurality of pipe sections (1), wherein each pipe section (1) comprises: an inner metal pipe section (11), and an outer non-metal pipe section (12) composed of a fiber composite material, wherein the outer non-metal pipe section (12) is wound around the inner metal pipe section (11), such that the inner metal pipe section (11) protrudes by a preset distance from both ends of the outer non-metal pipe section (12) to form outer joint sections (13), adjacent inner metal pipe sections (11) are welded to each other to form an inner metal pipe, the fiber composite material is wound around the outer joint sections (13) to form an outer non-metal pipe together with the outer non-metal pipe sections (12); and a wire (2) connected to the inner metal pipe (11) at a preset position. The pipe system further comprises a fiber composite reinforcement layer wound around the fiber composite material on the outer joint sections (13) and around a joint between the fiber composite material on the outer joint sections (13) and the fiber composite material of the outer non-metal pipe sections (12). The pipe system is resistant to both direct and alternative current interference.
