Pipe Corrosion Detection Spark Detector, Porosity Holiday Detectors Holiday Detector Test

HD-101

Porosity Detector is employed in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for corrosion protection over metal and concrete (conductive) surfaces.
With corrosion an extremely costly and disruptive worldwide problem, preventative determination becomes essential.
For newly constructed tanks, pipelines and other installations, where corrosion prevention coatings have had to be applies, specifications will normally call for a specific coating to a specific thickness. By using a our Detector to verify the competency of the sealing coatings, the contractor can be assures that his coatings responsibility has been met. In terms of cost effectiveness, with the low capital and operating costs of the Detector, the contractor will have some protection from claims at a very low price.

Principle
The detector generates a high DC voltage that is applied to the coating surface through a probe. The detector is connected to the substrate via the high voltage returned. When the probe is passed over a coating flaw, then the electrical circuit is completed and current flows from the probe to the substrate. As a result, audible and visual alarms are activated in the detector and a spark may be produced at the flaw.

Functions

On-Line Holiday Detector HD-120M is special testing equipment used to detect oil and gas pipelines, cables, enamel, metal tank, hull and other protective coatings flaws. It is professional and practical equipment.
