Water-consuming units and high water-consuming enterprises such as factory areas, being major consumers of energy, have always been at the forefront of water conservation and emission reduction efforts in comparison to other industries. However, due to the repeated issues of aging pipelines, deteriorating networks, and leakages, the water loss in some factory areas continues to increase. Despite ongoing leakage detection efforts, constraints due to working conditions, environment, and other factors make it difficult to thoroughly resolve leakage issues. Easysight has developed a targeted pipe inspection system based on the characteristics and working environment of factory areas, providing technical support for enterprises to conserve energy and reduce consumption.
High Environmental Noise Interference
Leakage detection in factory areas differs from that of municipal units. While municipal pipeline leakage detection can opt for nighttime operations in high-noise environments, most factories, due to 24/7 operation of production facilities, cannot avoid environmental noise. For safety reasons, leakage detection operations are not allowed at night in factories, posing higher requirements for detection work.
High Safety Requirements
Safety requirements in factories are stringent, with flammable and explosive items strictly prohibited from being brought into the plant. Leakage detection equipment must be explosion-proof, and drilling to verify leak points is not allowed. These requirements increase the difficulty of detection.
Variety of Pipeline Networks
Factory pipelines are relatively complex, including various types like fresh water, circulating water, high-pressure and low-pressure firefighting water, etc., in the underground waterline. The materials of the pipelines are also diverse, such as ball mill cast iron, fiberglass pipes, steel pipes, PE, PVC, etc. The volume of pipeline inspection work is large and challenging.
Lack of Pipeline Data
Factory pipeline drawings and data are often missing or inconsistent with the current situation. With increasingly more projects and the continuous expansion of factory scales, the addition of new facilities makes the original drawings and data unable to meet the actual pipeline maintenance needs. The lack of professional pipeline detection and GIS measurement personnel leads to delayed updates of pipeline information, causing inconveniences to leakage detection work.
In response to the complex environments and diverse needs of factory areas, Easysight provides multiple pipe inspection systems to ensure efficient and accurate leakage detection.
Ground Listening Method
Using specialized equipment like leak detection machines and listening rods, this method involves collecting, amplifying, and analyzing the sound signals of underground pipeline leaks to identify leak points. It is suitable for detection in non-facility areas with low noise interference.
Correlator Detection Analysis Method
When a pressure pipeline leaks, placing two sensors on either side of the suspected leak point allows leak sound waves to travel along the pipeline. The difference in arrival time at the sensors creates a time difference. Based on the time difference and the distance between the sensors, the leak point can be accurately calculated. This method is especially suitable for areas with high environmental noise interference or deeply buried pipelines, enabling high-precision pipeline leakage detection.
CCTV pipe inspection system is suitable for detecting various leaking pipelines. It provides clear images of the inner wall of the pipeline, especially for large diameter pipelines made of PE, PVC, ceramics, cement, and deeply buried or difficult-to-detect pipelines. The equipment used is a CCTV pipeline inspection robot, capable of comprehensive detection of the internal conditions of pipelines.
Tracer Gas Detection Method
Injecting a hydrogen-nitrogen mixed gas (5% hydrogen and 96% nitrogen) into sealed pipelines, abnormal pressure tests confirm the leaking section. Using a hydrogen detector along the pipeline direction helps pinpoint the exact location of the leakage. This method is suitable for various pipeline detections due to its safety, non-toxicity, non-flammability, and high detection accuracy.
Infrared Imaging Detection Method
The infrared imaging method uses temperature changes near the leak point to determine the leak location. This method is unaffected by environmental noise and testing distance, has a broad detection range, and is suitable for leak detection in facility areas, steam pipelines, and circulating water pipelines.
Information Technology Construction
Easysight combines features of water systems, working environments, and industry characteristics, selecting different detection methods to meet the needs of system leak control. Meanwhile, information technology is utilized to conduct full-scale underground pipeline detection, forming comprehensive and accurate underground pipeline drawings and data. A geographical information system (GIS) is established to monitor various water system pressure, flow, etc., in real-time, achieving dynamic monitoring and control of the underground water network, improving detection efficiency, and laying a solid foundation for water conservation and consumption reduction efforts.
Through the above multiple pipe inspection systems and methods, Easysight helps factories resolve leakage issues, improve detection efficiency, ensure safe production, and energy conservation and emission reduction, providing comprehensive technical support to enterprises.
