Special Emphasis Programs by MISTRAS
Custom Corrosion Under Insulation (CUI) Programs
Estimates indicate that corrosion under insulation (CUI) alone costs the chemical and oil & gas industries over $100 million each year. Without an effective CUI protection program, the damage can be difficult to detect, harder to mitigate, and comes with even greater cost.
As the industry’s truest one-source provider of asset protection solutions, MISTRAS Group has the resources, knowledge, and subject matter experts (SMEs) to implement and manage all phases of your CUI program.
An effective CUI program requires experts in engineering, inspection, systems, light mechanical services, and at-height work, and should include prevention, early detection, mitigation, and preventative maintenance programs.
MISTRAS’ CUI programs are broken down into five steps, each custom-tailored to your operation.
DiscoveryTo prescribe the most efficient program, our engineering SMEs conduct a rigid review of current operating conditions. For at-height or confined spaces, we can recommend unmanned drones for preliminary visual inspection, and we’ll construct scaffolding or deploy rope access teams as the job requires.
Visual & Qualitative InspectionOur API-certified inspectors then conduct visual inspections to get a first look at the potential problem areas, after which they’ll determine and perform the appropriate qualitative inspection technique (see back page for the inspection technique that’s right for you).
Inspection Prep Our expert mechanical service technicians prepare areas for quantitative inspection, through combinations of insulation removal, corrosion mitigation, and surface preparation.
Quantitative Inspection We can deploy a variety of quantitative inspections to determine corrosion severity, including ultrasonic thickness, phased array, and radiography. Localized vs General corrosion, radiation concerns, and access to the asset guide the decision process.
Reporting of Results We deliver the project’s report using ACAD drawings to the owners. We can also input findings straight into a facility’s Inspection Data Management Software (IDMS), including MISTRAS’ proprietary PCMS® software.
