Corrosion Under Insulation (CUI): A Case Study

Res POWERTHERM CONTRACT SERVICES LTD Corrosion Underoords Insulation (CUI) A Case Study CUI is a very acute form of localised corrosion caused by the presence of moisture on the external surface of insulated equipment. Here we take a look at a case study where a wide range of services were carried out by Powertherm contract Services off-site at a vessel fabrication facility. Procedures to minimise the effects of CUI were executed on a significant pressure vessel before it was transported to site. Project Rationale Requirements for a replacement pressure vessel for operations at a refinery in the North of England. Project Details Contract Type: Installation Industry: Vessel Fabrication Services: Access, Surface Preparation, Coatings, Insulation Workforce: 11 (Scaffolding, Painting & Insulation Operatives) Timescale: 6 weeks Scope of Services Access: Our access division began the project by constructing an independent scaffold for works to be carried out. For the surface preparation and specialist coatings phase of the project, our scaffolding operatives erected a temporary roof. They also added sheeting to the structure to provide encapsulation to reduce egress of materials and prevent any potential contamination. Surface Preparation & Specialist Coatings: Our painting operatives began high-pressure blast cleaning the vessel to clear the surface of any contamination. They then applied Thermally Sprayed Aluminium (TSA) to the vessel to help combat Corrosion Under Insulation (CUI). Insulation: The final phase of the project saw our thermal insulation engineers install a bespoke 4" (100mm) foam glass insulation system to the dome ends and main body, and finish off the vessel with a 304 stainless steel cladding. Site Details Location: North of England Type: Petrochemical End User: A refinery in the North of England. Project Outcome High-quality, on-time, on-budget, and safe execution of our multi-service offering on a landmark pressure vessel for a specialist client. brds Heothu Powertherm Contract Services is a multidisciplinary industrial service provider with 30 years of experience, offering a range of industry-renowned services across the UK.
