The technology

The patent pending non-contact corrosion scanning provides a fast method of corrosion detection in inaccessible areas or where direct contact to the structure is not possible without prior preparation. The technology allows for improved safety, reduced costs and minimises maintenance downtime.

Applications

  • Corrosion issues – Oil & Gas - Corrosion Under Insulation or CUI is estimated to incur 60% of the process plant maintenance costs.

    Current methods require removal of the insulation prior to Non Destructive Testing or NDT inspection in order to identify potentially very small areas of corrosion. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion Issues – Nuclear & refineries - Pipework systems within industrial power plants contains a high concentration of concealed pipework. Pipes may be covered in concrete, clad, lagged or difficult to access. This concealment of pipework makes inspection and condition monitoring difficult. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion Issues – Water - Many of the water pipelines are legacy cast iron, buried under earth or concrete. Current methods is to remove the earth or concrete prior to inspection and repair. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion Issues – Construction - A major culprit in rebar corrosion is water penetration, which can lead to deterioration related structural problems. The USA spends circa $8.3 billion, directly on corrosion mitigation in their national highway bridges. The leading cause of corrosion in these bridges is the corrosion of the steel reinforcement. The size of the UK concrete repair industry is believed to be well in excess of £1 billion 3% of the entire construction industry.

    Current methods of corrosion assessment require invasive non-destructive testing of rebar in bridges, precast concrete slabs, columns and parking garages, which is costly and time consuming. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion issues – Oil & Gas - Corrosion Under Insulation or CUI is estimated to incur 60% of the process plant maintenance costs.

    Current methods require removal of the insulation prior to Non Destructive Testing or NDT inspection in order to identify potentially very small areas of corrosion. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion Issues – Defence & Marine - A preferred solution is the undertaking of non-destructive pipework or structure inspection without the prior removal of lagging, insulation or paint coating, whilst the vessel remains in situ. A non-contact scanning technique is preferable to reduce costs and time.
  • Corrosion Issues - Offshore Energy - Many of these applications are in inaccessible areas or require invasive inspection which costs considerable financial and time expenditure. Current methods of corrosion inspection require prior removal marine growth and crustacea. A non-contact scanning technique is preferable to reduce costs and time.
