Holiday Detector For Pipeline

A holiday detector is a non destructive detection method of testing.

Holiday detector for pipeline. The msrb plc rebar holiday detection system uses an inductive sensor to sense the approach of a freshly coated rebar batch after the rebar exits the cooling process which then activates the msrb plc holiday detection system to prepare for the rebar batch to pass through our dual roller wet sponge electrodes rbrs. The elcometer 266 holiday detector can be used to test porosity on coatings up to 7 mm 275 mils thick and is ideal for inspecting coatings on pipelines and other protective coatings this holiday tester features a built in voltage calculator which will determine and set the correct test voltage based upon the test standard and the thickness of coating being tested. 1 2 method a is designed to detect holidays such as pinholes and voids in thin film coatings from 0 025 to 0 254 mm 1 to 10 mils in thickness using ordinary tap water and an applied voltage of less than 100 v d c.
