Problems solved by technology

However, for RTP pipes, while non-metallic materials avoid corrosion, their electrical insulation makes many detection methods suitable for non-metallic pipes unable to act on RTP pipes, and the traditional pipeline detection method is point leakage detection, which cannot realize long-distance pipelines. Coverage, and there are disadvantages such as untimely forecast, poor positioning accuracy and high false alarm rate

Embodiment 1

[0037] The intelligent RTP pipe of this embodiment has a structure such as figure 1 As shown, it includes an inner tube 1 and an outer tube 4. An enhanced sensing layer is provided between the inner tube 1 and the outer tube 4. The enhanced sensing layer is composed of a composite tape wound on the outer wall of the inner tube 1 at a predetermined winding angle. The winding angle is 50-60°. The composite tape includes a group of pretensioned reinforcing fibers 2 that are evenly distributed side by side along the axial direction of the inner tube, and several sensing optical cables 3 are uniformly distributed in the reinforcing fibers 2, and the sensing optical cables 3 are arranged adjacent to the reinforcing fibers 2, and the sensing optical cables The length of 3 is greater than that of the reinforcing fiber 2, so that the end of the composite tape has a sensing optical cable 3 extending outward. The pretensioning stress of the reinforcing fiber 2 is 100±20 Newton, the dist...

Abstract

The invention relates to an intelligent RTP tube. The intelligent RTP tube comprises an inner pipe and an outer pipe. A reinforcing sensing layer is arranged between the inner pipe and the outer pipe and composed of a composite tape wound on the outer wall of the inner pipe at a preset winding angle. The composite tape comprises a group of pre-tensioned reinforcing fibers uniformly distributed side by side in the axial direction of the inner pipe. A plurality of sensing optical cables are uniformly and adjacently distributed among the reinforcing fibers. According to the intelligent RTP tube, the optical cables are embedded into the pipe for avoiding re-laying the optical cables, protecting the optical cables, enabling the optical cables to be suitable for demanding working conditions, performing safety monitoring and data transmission for the RTP pipe, achieving functions of fluid transporting, signal transmitting, leakage monitoring and strain monitoring of the pipe during operation and accordingly ensuring the safe operation of the pipe.

Description

technical field [0001] The invention relates to an RTP pipe, in particular to an intelligent RTP pipe with an optical fiber sensor monitoring function, and also relates to a preparation method thereof, belonging to the technical field of intelligent monitoring of non-metallic flexible pipes. Background technique [0002] Today, when energy is increasingly scarce, oil and natural gas are important energy reserves, and its exploitation is of great importance to the country. The use of pipelines to transport oil and natural gas is economical and efficient, and has been widely used at home and abroad. In the past, most of the oil and gas extraction industry used various steel pipes for transportation, and the most prominent problem of transporting steel pipes was corrosion. In order to achieve technological innovation and economic optimization, the oil and gas industry has increasingly adopted non-metallic pipelines (NMP) in recent years. There are abundant oil and gas reso...
