VIDEO: Elmed’s new in-plant holiday detector

Hydrocarbon Engineering,


In addition to its portable holiday detectors, Elmed Messtechnik GmbH is now offering the ISOTEST act P2, a stationary holiday detection system designed for the automated testing of coated pipes.

The product has been developed for the testing of factory coatings of all conventional coating materials, and facilitates stationary holiday detection using one testing device. The all-rounder offers necessary voltages for the safe testing of FBE (fusion bonded epoxy), as well as three-layer PE/PP coatings, according to international standards and specifications.

Both helical and circumferential testing of pipe coatings is possible with the ISOTEST act holiday detection system, thanks to flexible components and suitable accessories. Using a unique impulse test voltage, even fully coated pipes without ‘bare pipe ends’ can be reliably and economically tested for cracks and pinholes.

The capacitive grounding of the pipe is applied by means of special electrodes similar to the principle of a capacitor. These electrodes can be integrated with little effort in the existing roller conveyor. The application of capacitive grounding (phantom grounding) is one of the main advantages of the impulse voltage, when compared to conventional holiday detector systems using constant DC voltages.

Even damp surfaces can be quickly, reliably and non-destructively tested for absence of porosity. A large variety of test electrodes of different materials, shapes and sizes guarantee the safe and reliable porosity testing of coatings, linings and foils without material stress.
