Intelligent thermally-insulating pipe provided with alarm device

Abstract

The invention discloses an intelligent thermally-insulating pipe provided with an alarm device. The intelligent thermally-insulating pipe comprises a thermally-insulating pipe body composed of a steel pipe, a thermally-insulating layer and an outer protective pipe and further comprises a test wire, an alarm wire, an outgoing joint, an outgoing line and inspection equipment. The test wire and the alarm wire are parallel with the axis of the steel pipe and pre-buried in the thermally-insulating layer, wherein a set distance is maintained between the test wire and the alarm wire and the outer side face of the steel pipe. The outgoing joint is fixed to the position, located at a preset monitoring point of the thermally-insulating pipe, of the outer protective pipe. Two outgoing heads are arranged on the outgoing joint, wherein the two outgoing heads are insulated to each other and connected with the steel pipe and the test wire or the alarm wire correspondingly. The outgoing line is connected between the outgoing joint and the inspection equipment. A plug matched with the outgoing joint is arranged at one end of the outgoing line, and a joint which is connected with the inspection equipment in a matched manner is arranged at the other end of the outgaining line. The intelligent thermally-insulating pipe provided with the alarm device is reasonable in structure and convenient to operate; the leakage problem of the thermally-insulating pipe can be found quickly; the thermally-insulating pipe can be repaired in time conveniently; and the situation that the thermally-insulating layer is eroded and carbonized due to leakage of a high-temperature medium in the pipe is avoided.

Description

Technical field [0001] The invention relates to the technical field of heating pipeline monitoring, in particular to a prefabricated directly buried thermal insulation pipeline with an alarm device. Background technique [0002] Insulation pipe is the abbreviation of insulated pipe. It is used for the transportation of liquid, gas and other media. It is widely used in the thermal insulation engineering of petroleum, chemical, aerospace, military, central heating, central air conditioning, municipal and other pipelines. [0003] Generally, the insulation pipe is divided into a three-layer structure from the inside to the outside. The first layer: working steel pipe layer, referred to as steel pipe. The steel pipes generally choose seamless steel pipes, spiral steel pipes and straight seam steel pipes according to customer design and requirements. After the surface of the steel pipe is treated by the shot blasting process, it meets the requirements of the relevant standards. The s...

Problems solved by technology

[0004] Most of the medium conveyed by insulation pipes are concealed projects, and they pass through areas with complex conditions, many points, long lines, and wide areas. After a leakage accident, it is difficult to find or determine the location of the leakage in time, which may lead to a major accident.

At present, urban insulation pipes still adopt the manual inspection and leak detection method with relatively backward technology. The inspectors regularly carry relevant leak detection instruments along the pipeline for inspection. This may not be discovered until a long time after a leak occurs, which will increase maintenance. Difficulty, and even cause accidents
