Insulating flange leakage will reduce the effective protection of cathodic protection stations, increasing the output current cathodic protection stations. Sacrificial cathodic protection of pipelines quality insulating flange suppliers, mostly due to the large insulating flange leakage is less than the required ground. Today we look at insulating flange leak detection methods are: the direction of current law, the current law pipes, grounding resistance method. Insulating flange leakage mostly piped medium containing conductive material insulating flange manufacturers, or the conductive material adhered to the insulating spacer caused. Pipeline cathodic protection tube station after clearing the output current is reduced along the pipe, ground potential negative shift, which is to adhere to the insulated conductive gasket material clear or partly clear pigging amazing results. Due to the length of the overall type covering layer of insulating joints many times greater than the thickness of the insulating insulating flange gasket, so its insulation resistance. As the insulating flange insulation resistance was much larger than the metal short point contact resistance, so if insulating flange leakage and short circuit pipe ends at a distance from each other at close insulating flange, thus short circuit current is insulating flange leakage leakage current Many times, usually after a short circuit troubleshooting, in order to clearly show insulating flange leakage. Flange insulation pipe system has been used in many of the world, and these systems serve as the indispensable role - to prevent current conduction. In the city gas distribution projects, city gas distribution projects for low pressure, the pressure characteristics of the pipe network improvements. Sets of pads will wear steel flange bolt holes expanded to be able to wear insulating sleeve pad; thus ensuring pad sets fit within the aperture of the original novel insulating flange during the cathodic protection Louzhuang valve at the transmission and distribution network and the need for potential points isolated pieces of buried pipe valve wells used. Be buried pipeline network fragmentation isolation can be more clearly grasp the cathodic protection of each piece pipe network; fragmentation of cathodic protection evaluation, processing for different cathodic protection case; when the same protection potential of adjacent sheets When and to protect potential requirements, available across both sides of the insulating flange connected unified protection; When the protective potential of adjacent sheets and there is a larger difference when requested protection potential reach of films that will not reach the protection potential The chip requires special handling until it meets the requirements so far, later merging operation.
