Your CUI Specialists™

Corrosion Under Insulation (CUI) Products

Corrosion Under Insulation (CUI) can no longer be considered an ‘out of sight, out of mind’ issue. Ageing infrastructure has brought CUI to the forefront, with costs surrounding CUI related problems estimated to be in the billions of dollars each year. However, this number can be greatly reduced by implementing systems which allow for early detection, access for inspection, ongoing monitoring, moisture mitigation, and safeguards to isolate problem areas. While there is no way to fully prevent CUI, mitigation and monitoring strategies can greatly reduce the incidence and costs (human, capital, social, and environmental) of CUI.  

At Integrity Products & Supplies, we pride ourselves on being CUI Specialists™. Our in-house R&D team combined with global procurement allow us to provide innovative and cost-effective solutions to CUI problems. Our Corrosion Under Insulation products are designed to work together as part of a holistic CUI monitoring and mitigation system, or on their own, depending on the needs of each specific application.   

Our product line is constantly evolving, so for the most up to date solutions to fit your needs, contact us directly.  

Integrity Insulation Ventilation System 

The Integrity Products Insulation Ventilation System (IVS) is a 3-part system consisting of Integrity Perforated Dimple Wrap™, Integrity Vents™ and Integrity Drains™. These work together to promote airflow along the insulation system which limits moisture and condensation build-up in the insulation and can assist in drying out wet insulation.

INTEGRITY VENTS™  Integrity Products Integrity Vents™ provides ventilation to the insulation system. The louvered design protects the insulation from water ingress while promoting airflow along the insulation system. These are installed every 3m at the 3 and 9 o’clock positions. They make use of the air gap created by the Integrity Perforated Dimple Wrap™.

INTEGRITY DRAINS™  Integrity Products Integrity Drains™ are designed to create a drainage point for moisture ingress while also promoting airflow along the insulation system. These are gravity-assisted and as such are installed at the 6 O’clock position in the metal cladding. They make use of the air gap created by the Integrity Perforated Dimple Wrap™

INTEGRITY PERFORATED DIMPLE WRAP™ Integrity Products Integrity Perforated Dimple Wrap™ creates a consistent 6mm air gap between the insulation and the metal cladding. Each sheet is perforated with 8 holes per sq inch which allows any moisture trapped in the insulation to pass through to the outer cladding and drain away

Integrity Tank Chime Spacer

Typically any insulated storage tank is susceptible to corrosion under insulation (CUI) and tank failures. The problem begins when moisture ingress in the storage tank’s insulation moves vertically down alongside the tank shell, collecting at the bottom over the tank chime, around the shell plate and the weld joints. With the absence of any drain points or stand-offs, the moisture is trapped, causing CUI and costly failures. Integrity Products Tank Chimes Spacer is designed to create a horizontal (i.e. alongside bottom plate axis) stand-off between the storage tank chime and the edge of the insulation to allow drainage of the accumulated or trapped moisture before it can cause significant corrosion on the chimes and weld joints. This also provides access for NDE/NDT companies to perform visual and mechanical inspections.
