Corrosion Under Insulation

Cor­ro­sion un­der In­su­la­tion (CUI) is a severe threat to the pro­cess in­dustry. If neg­lected, the cor­ro­sion pro­cess is mostly well-hid­den un­der the in­su­la­tion sys­tem and only be­comes ob­vi­ous due to severe in­teg­rity fail­ures.

CUI In­spec­tion and Re­medi­ation

KAEFER has ex­tens­ive ex­per­i­ence in as­sess­ing and re­medi­at­ing Cor­ro­sion Under In­su­la­tion (CUI) since in­cep­tion in 1918. Our aim is to provide cli­ents with an ef­fi­cient ser­vice that re­duces the cost of identi­fy­ing CUI, im­proves plant thermal ef­fi­ciency and helps pre­vent ma­jor fail­ures and un­planned plant shutdowns.

KAEFER utilises real time ra­dio­graphy for CUI in­spec­tion – KAEFER In­su­lated Pipe Scanning equip­ment. We refer to this as KIPS.

We have ded­ic­ated and ex­per­i­enced CUI in­spec­tion tech­ni­cians who util­ise the fol­low­ing 4-step pro­cess to identify CUI:

  1. Carrying out Thermal Imagery Surveys complete with thermal efficiency results and CUI indicators
  2. Undertaking Real Time Radiography (RTR) scans and Moisture Content Measurement (MCM), concentrating on CUI indicators results from our thermal imagery surveys
  3. Non-destructive Testing (NDT) where/when applicable to confirm wall thicknesses
  4. 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.

KAEFER has previously carried out in­spec­tion ser­vices for a number of clients in Australia across the Oil & Gas, Power and Chemicals sectors.

Remediation Solutions

Once CUI has been iden­ti­fied, KAEFER can provide a re­medi­ation solu­tion utilising a num­ber of coat­ing and in­su­la­tion solu­tions. We consider factors such as en­vir­on­mental & process, cost, safety, life ex­pect­an­cies and qual­ity requirements.

KAEFER has a ded­ic­ated R&D test­ing fa­cil­ity in Kwinana, West­ern Aus­tralia, to sim­u­late on-site con­di­tions for these solu­tions.
