High-voltage holiday/pinhole detector
Coating integrity testing, quality assurance
Marine, oil & gas, infrastructure, tanks
High voltage is applied to a brush probe that passes over the coating; pinholes create a spark that triggers an alarm.
High-voltage spark testing reveals pinholes and thin spots in protective coatings before they cause corrosion.
| Voltage | 1-30 kV |
| Sensitivity | 100 microns |
| Probe | Brush/sponge |
| Alarm | Audible/visual |

Large pressure blast pot with 500L metallic capacity, 230L sand capacity, 11-15 sq.m/hr cleaning rate. Workhorse for heavy industrial use.

On-site and Mahape-unit blasting of tanks, vessels, pipelines and structures to ISO 8501-1 Sa 2.5 / Sa 3. Copper slag, steel grit or garnet to spec.

Epoxy, PU and zinc-rich coating on blasted steel. On-site MMR crews or the Mahape unit. DFT and holiday checks to the paint data sheet.

Copper slag abrasive for aggressive surface preparation. Hard, angular, cost-effective for large areas.
Dial-type surface profile gauge for measuring blast profile depth on metal surfaces.
Portable dew point meter for measuring relative humidity, dew point and surface temperature.
