Flanges are important components used to connect pipes; when transporting toxic, high-temperature, flammable, or corrosive substances through pipes, flanges can be damaged and cause leaks. A visual leak detector can be used to detect leaks in flanges from a distance, thereby preventing harm to the environment and people. Flanges and their functions: A flange is a disc-shaped component that is very common in piping projects, and flanges are always used in pairs. In pipeline engineering, flanges are mainly used for connecting pipelines. A flange is installed at each end of the pipe that needs to be connected; threaded flanges can be used for low-pressure pipes, while welded flanges are used for pipes under a pressure of 4 kilograms or more. A seal is added between the two flanges, and then they are tightened with bolts. Flanges under different pressures have different thicknesses and require different bolts. When water pumps and valves are connected to pipes, the corresponding parts of these devices are also made in the shape of flanges, a connection method known as flange coupling. Any connecting component that uses bolts to join two planes together at their perimeters and thereby seals them is generally referred to as a \"flange\"; for example, in the connection of ventilation ducts, such components can be called \"flange-type components\". Its main functions are: 1. To connect pipelines and maintain their sealing performance ； 2. Facilitates the replacement of a certain section of pipeline ； 3. Easy to disassemble for checking the pipeline condition ； 4. Facilitates the sealing of a certain section of pipeline. Reasons for flange seal leakage: Flange seals rely primarily on the pre-tightening force of the connecting bolts, and through gaskets, they achieve a sufficient sealing pressure in order to prevent the leakage of the pressurized fluid being sealed. There are many reasons for leakage: insufficient compression force on the gasket, roughness of the mating surfaces that does not meet requirements, deformation of the gasket, and mechanical vibrations – all of these can lead to poor sealing between the gasket and the flange surfaces, resulting in leakage. In addition, bolt deformation or elongation, gasket aging, reduced resilience, and cracking can also lead to poor sealing of the flange surfaces and resulting leaks. There are also human factors that cannot be ignored in flange leaks; for example, improper installation of the gaskets can result in insufficient local sealing pressure or excessive force, exceeding the design limits of the gaskets. Additionally, uneven force applied during flange tightening or an offset between the centerlines of the two flanges can lead to a false sense of tightness, all of which can facilitate leakage. Advantages of visual leak detectors: 1. Leaks in flanges are generally difficult to detect; if the interior contains toxic or harmful substances, high-temperature gases, or similar materials, it can cause harm to the operators. By using a visual leak detector, it is possible to quickly and easily locate the source of the leak, thereby allowing the issue to be resolved safely. 2 During routine inspections, operators generally detect flange leaks by visual inspection, smelling, and touching, which is a labor-intensive process and unsafe. Using an infrared spot thermometer can easily lead to missed detections, whereas a visual leak detector can safely and conveniently identify the location of leaks. The 3 LeakShooter has been patented; it is the first of its kind in the world to provide leakage visualization by accurately displaying the location of leaks on a color screen. At the same time, a digital photo is taken, and these two elements are combined to facilitate the identification and localization of faults, enabling prompt and correct repair. The 4 LEAKSHOOTER series of leak detectors are equipped with powerful software for storing and analyzing leak images and generating professional reports. With this software, it is possible to analyze data stored on a PC, thereby improving the security and convenience of inspections. How to use the LKS1000 visual leak detector? During the on-site scanning process, once the sensors detect leakage signals, they convert them into audio signals that can be heard by human ears, which are then displayed simultaneously on a large color LCD screen. On the liquid crystal screen, the leakage source appears as a real-time visible image in yellow (indicating low leakage and a weak signal) or red (indicating high leakage and a strong signal). At the same time, the effective value and maximum value of the continuous sound volume in decibels are displayed in different colors and numbers via the horizontal light bar at the bottom of the LCD screen. “The “LEAKSHOOTER” leak detector is equipped with a dedicated software data cable. Using this software, it is possible to transfer the images stored in the instrument’s memory (the memory can hold 1000 images) to a computer. All images display the date, time, and dB level, and it is possible to manually number the images. Other measurement functions of LKS1000: ■ Detection of internal leaks in valves and hydraulic systems ■ Detection of pump cavitation and internal leaks in air compressors ■ Detection of faults in air strainers ■ Detection of compressed air leaks, as well as leaks in boilers, heat exchangers, and condensers ■ Identification of safety doors related to boiler faults ■ Detection of wind noise and water leaks ■ Inspection of mechanical components such as bearings and gearboxes ■ Inspection for partial discharge in electrical equipment: identification of faults in GIS switch actuation mechanisms, detection of contamination-induced flashover and internal cracks in insulators; detection of partial discharge at cable joints; detection of internal partial discharge faults in GIS/GCBs, switchgear, power distribution cabinets, and communication cabinets; detection of partial discharge in transformers, busbar bushings, CT/PT devices, capacitors, and reactors; detection of SF6 gas leaks.
