CUI - Corrosion Under Insulation

Power & Utilities

CUI is a major concern for industry in general. Over the past 20 years CUI related failures have cost industry tens of millions in plant downtime, repair and replacement costs and lost opportunity for profit.

CUI - Corrosion Under Insulation

Fundamentally CUI is caused by the ingress and trapping of moisture into the insulation system. A system, which many believed was watertight. The reality is that so many opportunities exist for moisture to enter an insulated system that it is almost impossible to guarantee it will not re enter.

Hertel have developed methodologies to assist our customers to identify areas where CUI is likely to occur. For instance, improved quality management processes to mitigate moisture ingress, products to allow process related moisture ingress to drain from the system and inspection ports to enable routine non-intrusive inspections to critical pipe work and equipment to be carried out.

Quality Assurance

Hertel moved away from site based insulation workshops many years ago and now employ the latest techniques in dedicated facilities.

Employing leading edge plasma arc cutting technology to manufacture jacketing components not only provides significant efficiencies (reduced manhours) the technology also contributes significantly to waste minimisation and end product quality.

The benefits to our customers include:

Consistent - Superior finished quality
Reduced work face and at risk site hours
Reduced costs
Reduced site based non-productive time
Job specific material packaging – all materials delivered for a specific workscope together

Coupled with our removable modular mat manufacturing facility all required insulation components are available from one source.
