Leak detection of polypropylene reinforced fiber anticorrosive tape
The leak detection of polypropylene reinforced fiber anticorrosive tape is done well, which enhances the safety of the whole project, one is electric spark leakage detection, and the other is voltage leak detection. Polypropylene anticorrosive tape
一分彩The EDM leak detection index mainly controls the defects caused during construction or certain defects of the polypropylene reinforced fiber anticorrosive tape, so it must be 100% tested. The leak detection voltage for pinhole inspection is to consider not only to detect small pinholes, but also to ensure that the intact coating is not penetrated. At the same time, the leak detection voltage value must be consistent with the actual voltage level of the EDM detector used.
一分彩运用 In the prefabrication stage and on-site, use a direct current power supply EDM leak detector to conduct a full line inspection of the pipeline, and check the anticorrosive cold wrap fill points and wound repairs one by one. The leak detection probe moves at a speed of 0.3m / s, and it is qualified that it does not spark.
一分彩漏 The leakage detection voltage of polypropylene reinforced fiber anticorrosive tape is determined according to the following formula: when TC <1mm, V = √3294; when TC≥1mm, V = √7843. Where V = leak detection voltage (V); TC = anti-corrosion layer thickness (mm).
一分彩At this point, it should be noted that the insulation voltage of polypropylene reinforced fiber anticorrosive tape and the leak detection voltage are two completely different concepts. You cannot use the insulation voltage value for the EDM leak detection test. During the leak detection process, the surface of the anticorrosive layer must be kept dry, and the detection electrode must be kept at least 13 mm away from the end of the metal tube or the bare metal leakage surface.
一分彩The above is the knowledge about leak detection of polypropylene reinforced fiber anticorrosive tape, I hope to help you.
