Pipeline Manufacturing Co., Ltd. Hebei billion in gold (www.yijinguanjian.com) is located in Cangzhou City, Hebei Province, Yanshan Puwa Industrial Development Zone, Contact: Alan Li Tong insulating flange leakage will reduce the effective protection of cathodic protection stations, increasing output current cathodic protection station. Sacrificial cathodic protection of pipelines, 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 prices high voltage insulation flange, or 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. Insulated joints due to the overall length of the cover layer is larger than the thickness of the insulating gasket many times, so the 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. Static electricity in the production, transportation, life is everywhere, all-pervasive, it brings to life a little trouble ranging from weight is caused by a major accident. Antistatic insulating flange applications effectively cut off from the ship shoreline electrostatic conductive connection to protect the safety of the ship shoreline electrical connection. Because I ship shoreline domestic oil pipeline accidents continue to occur due to static electricity conduction, electrostatic transfer to a device loaded with flammable petroleum oil drums, oil tankers and other years, with the possibility of making a lot of oil combustion, explosion insulating flange, resulting in serious accidents. Installation antistatic insulating flange can effectively protect the ship, although the shoreline electrical connections are secure, but in the case of aging equipment may be damaged or have an accident. In the ship shoreline antistatic insulating flange lifetime maintenance and inspection must be done regularly, replace insulating flange leakage, improve audit inspection procedures insulating flange manufacturer installed correctly use antistatic insulating flange. Hose or hose connection with onshore pipeline loading arm must be installed in order to play a blocking insulating flange static current role while installing insulating flange should ensure that pipelines and vessels and shore side ground or ground to ensure Oil pipeline no static nuisance. Shoreline between the boat grounded jumper cables can not play the same role with the insulating flange insulating flange mounting is a top priority. Specializing in the production of gold Hebei billion pipeline flange insulation, insulation joints, anti-static dielectric insulating flange steel flange manufacturers, insulation performance, air tightness, reasonable prices, before the welcome.
