The Best Manufacturing Factory for Fiber Optic Leakage Detection Distributed Fiber Optic Sensing System in Oil Pipeline-INNO

Pipeline transportation is one of the international transportation methods for goods, which uses underground pipelines to transport crude oil, природный газ, refined oil, жижа, coal slurry and other media to their destination. Compared to other transportation methods, it has the advantages of large capacity, unrestricted by climate and other ground factors, непрерывная работа, и низкая стоимость, and has become an important way for oil and gas transportation. Due to the fact that long-distance oil and gas pipelines are mostly distributed in deserted areas such as the wilderness, they are susceptible to external human damage (such as drilling holes to steal oil, и так далее.) and sudden natural disasters (Например, землетрясения, Оползни, и так далее.), resulting in pipeline fractures and oil and gas leakage accidents; Также, due to the shallow burial of pipelines, they are often threatened by various construction activities when passing through residential areas, as incidents of damage and pipeline excavation caused by barbaric construction often occur. Oil and gas pipelines have the characteristics of high temperature, высокое давление, воспламеняемость, и взрывоопасность. Как только произошла утечка, Это не только останавливает трубопровод, но и серьезно загрязняет окружающую среду, представляющие серьезную угрозу жизни и имуществу местного населения. Если это вызывает возгорание и взрыв вытекшей нефти и газа, the consequences are unimaginable. Pipeline transmission has many advantages such as economy, эффективность, безопасность, и стабильность, and is applied in the transportation of fluids such as oil, природный газ, and water. With the continuous progress of social economy and technology, pipeline laying has been widely used. Pipeline systems are widely used in industrial fields such as petroleum, металлургия, urban water supply, и природный газ. The issue of pipeline safety protection is also increasingly prominent in front of people. Pipelines are buried underground year-round and are prone to corrosion, fatigue damage, or leakage, что не только наносит значительный экономический ущерб, но и загрязняет окружающую среду.. Следовательно, изучение эффективных методов обнаружения утечек трубопроводов чрезвычайно важно для обеспечения безопасной транспортировки трубопроводов..

Преимущества Распределенная система измерения температуры оптоволоконного трубопровода

Измерение температуры вокруг трубопровода для определения наличия утечки в настоящее время является широко используемым методом.. Однако, Традиционное измерение температуры представляет собой метод измерения в одной точке, и мониторинг состояния трубопровода требует размещения большого количества датчиков температуры., что создает трудности при строительстве и обслуживании. Волоконно-оптическая распределенная система измерения температуры представляет собой сенсорную систему, разработанную в последние годы для измерения пространственного распределения температуры в реальном времени.. Fiber optic is both a transmission medium and a sensing medium, and the temperature effect of backward Raman scattering can be used to measure the temperature of the fiber in real-time; The use of optical time-domain reflection technology can accurately locate measurement points. This system can measure the temperature field distribution over long distances in a short period of time. Due to the small volume of the optical fiber, the measurement process will not affect the distribution of the original temperature field. В то же время, it also has the characteristics of flame prevention, explosion prevention, коррозионная стойкость, и устойчивость к электромагнитным помехам. Следовательно, the optical fiber distributed temperature measurement system has good application prospects in the field of pipeline leakage monitoring technology.
The fiber optic distributed temperature measurement system based on Raman scattering technology is currently widely used as a pipeline leakage monitoring system. The oil and gas pipeline leakage monitoring system mainly consists of a распределенный волоконно-оптический temperature measurement host and corresponding temperature measurement optical cables, which continuously and linearly monitor the temperature of the pipeline in real-time, thereby monitoring the pipeline leakage situation. The entire monitoring system is connected to the pipeline SCADA system through its temperature measurement control host communication interface or dry contact relay terminals, and is responsible for providing alarm information and operation and fault signals to it.
When a leak occurs in a certain part of the pipeline, the system monitors a sharp change in temperature and quickly identifies the risk; By monitoring the gradual temperature changes of a certain section of pipeline over a period of time, it can be determined that there is an abnormal risk of leakage in the pipeline. The system can accurately locate the location of faults, repair pipeline faults, shorten time, and improve economic benefits for customers.

The oil pipeline fiber optic leak detection online safety monitoring system developed by FJINNO uses the IFDTS-SO distributed fiber optic temperature measurement system, which is installed in a cabinet and can be simultaneously connected to the upper service computer for comprehensive monitoring of the oil pipeline status. Combined with software display, sound and light, сеть, SMS and other alarm methods, it provides reliable guarantees for the safe operation of oil pipelines. The online monitoring system for oil pipeline fiber optic leakage detection consists of SRDTS-SO distributed волоконно-оптическая система измерения температуры, signal transmission unit, and signal processing unit. The signal transmission unit is one core of communication fiber laid along the oil pipeline.
