Introduction

Corrosion Under Insulation (CUI) is a prevalent issue in industrial settings, leading to equipment failures, safety concerns, and substantial maintenance costs.

One of the key challenges in addressing Corrosion Under Insulation (CUI) is the difficulty in inspecting and monitoring the condition of insulated piping and vessel systems.

In this blog post, we will explore the impact of CUI on these systems and discuss how the right inspection plugs can help prevent moisture infiltration while ensuring accurate Ultrasonic Thickness (UTT) inspections for fitness-for-service evaluations, as per API 579-1/ASME FFS-1.

We'll also shed light on NDT Seals, a company offering top-quality inspection plugs designed to maintain system integrity.

The Threat of CUI

Corrosion Under Insulation occurs when moisture is trapped beneath the insulation


material covering pipes, vessels, or other equipment.

This hidden corrosion can go unnoticed for extended periods, leading to severe damage and compromising the structural integrity of the equipment.
