KRONA-12 Electric spark flaw detector

The flaw detector allows continuous monitoring of polymer, epoxy and enamel coatings of pipelines with a diameter from 219 to 1420 mm and selective control of polymer, epoxy, enamel and bitumen coatings of pipelines of any diameter.

The flaw detector provides detection of local through defects of insulation coatings of pipelines with a dry surface.
The flaw detector allows for continuous monitoring
The flaw detector uses an electric spark control method.
The flaw detector is designed to work at:
- ambient temperature, °C: from minus 30 to plus 50;
- relative humidity at a temperature of +25°C, %: 98;
- atmospheric pressure, kPa: from 84.0 to 106.7.
