Corrosion Under Insulation
CorÂroÂsion unÂder InÂsuÂlaÂtion (CUI) is a severe threat to the proÂcess inÂdustry. If negÂlected, the corÂroÂsion proÂcess is mostly well-hidÂden unÂder the insulation system and only beÂcomes obÂviÂous due to severe inÂtegÂrity failÂures.
CUI InÂspecÂtion and Remediation
°ÄÃÅËIJ»ÏñÂÛ̳ has exÂtensÂive exÂperÂiÂence in assessing and reÂmediÂatÂing CorÂroÂsion Under InÂsuÂlaÂtion (CUI) since inÂcepÂtion in 1918. Our aim is to provide clients with an efficient serÂvice that reÂduces the cost of identiÂfyÂing CUI, imÂproves plant thermal efÂfiÂciency and helps preÂvent major failÂures and unÂplanned plant shutdowns.
°ÄÃÅËIJ»ÏñÂÛ̳ utilises real time raÂdioÂgraphy for CUI inÂspecÂtion – °ÄÃÅËIJ»ÏñÂÛ̳ Insulated Pipe Scanning equipÂment. We refer to this as KIPS.
We have dedÂicÂated and exÂperÂiÂenced CUI inÂspecÂtion techÂniÂcians who utilise the following 4-step proÂcess to identify CUI:
- Carrying out Thermal Imagery Surveys complete with thermal efficiency results and CUI indicators
- Undertaking Real Time Radiography (RTR) scans and Moisture Content Measurement (MCM), concentrating on CUI indicators results from our thermal imagery surveys
- Non-destructive Testing (NDT) where/when applicable to confirm wall thicknesses
- Remediation of affected areas – offering knowledge on the latest coatings and insulation/cladding technologies as preventative measures to safeguard against further CUI or loss of thermal efficiencies.
°ÄÃÅËIJ»ÏñÂÛ̳ has previously carried out inspection serÂvices for a number of clients in Australia across the Oil & Gas, Power and Chemicals sectors.
Remediation Solutions
Once CUI has been idenÂtiÂfied, °ÄÃÅËIJ»ÏñÂÛ̳ can provide a reÂmediÂation soluÂtion utilising a numÂber of coatÂing and insulation soluÂtions. We consider factors such as environmental & process, cost, safety, life exÂpectÂanÂcies and quality requirements.
°ÄÃÅËIJ»ÏñÂÛ̳ has a dedÂicÂated R&D testÂing facility in Naval Base, WestÂern Australia, to simulate on-site conÂdiÂtions for these soluÂtions.
