The RPR induction generator sends alternating current through an induction coil, which generates an electro-magnetic field. This magnetic field induces eddy currents in a conductive material like steel.
Due to the resistance of the steel, these currents are converted to induction heating. The heat is generated below the coating, resulting in quick and clean disbonding.
Fast & Cost efficient
Compared with Blasting and Water Jetting methods:
Considerable reduction in man hours
۵-۱۵ times faster on tough coatings
Energy costs reduced by up to 75 %
Minimum waste handling and disposal
HSE
Operator friendly; Quiet and no HAV’s
No use of dangerous high pressure hoses
Produces no airborne waste particles
Minimal operator safety equipment or gear required
No handling or disposal treatment of grit or water
Minimum waste removal – simple logistics and low costs
Environmental Benefits:
No airborne particle waste
Safer for operators and the environment
No water waste or wash-off
No contaminate of rivers and sea
No grit
Minimal waste, reduced handling and disposal
No noise
Safer for operators and co-workers
Local community not disturbed
This results in lower costs and better cooperation with local health authorities
Surface and Disbonding
Substrates and Precautions
Removal of different paints and coatings
Coating Disbonding
After Treatment
Works on carbon steel (magnetic substrates) and some Duplex steel types, depending on the steel properties
Rate of disponding and operator speed on the induction head will be determined by thickness, type of coatings and type of steel
Requires a minimum steel thickness of 4-5 mm to avoid damage on the backside coatings or insulation material used
Removal of different paints and coatings
Easy removal
Most types of standard paints and coatings on steel
Hard coatings like epoxies, urethanes, old alkyds etc.
Glass fibre linings
Fire retardant coatings (PFP’s)
Glued and vulcanized rubber
Difficult removal
Soft coatings like lanoline
Bitumen or other asphalt coatings
Chlorinated rubber
Zinc silicate and Iron oxide (need too high temperature)
