Portable MFL (Magnetic Flux Leakage) manually operated to externally scan and detect corrosion & pitting of pipelines, tanks and other steel structure.
Fast, Reliable Pipe & Small Vessel Screening.
Various scaning heads for multiple pipe sizes
The operator first connects the sensor cable between the scanning head and control module. Switch on the control module, set the required wall thickness and adjust the alarm sensitivity using a reference pipe with known artificial defects. Then simply set up the scanning head on the pipe to be inspected, push the scanning head and monitor the control module for the audible and visual alarm.
Any areas identified by the Graffin system can then be marked on the pipe for further analysis by a secondary inspection technique.
