Engineered for CUI (Corrosion Under Insulation) and Mechanical Integrity Testing.

Product Overview

Nextera’s NDT Inspection Plugs are accurately engineered closure items used to seal the inspection access ports after non-destructive testing (NDT) of insulated piping and equipment.
The plugs are engineered for harsh industrial use, offering repeat and consistent access to CUI-exposed locations without penetrating into the insulation system.

Constructed of corrosion-resistant materials such as stainless steel, silicone, and high-performing alloys, Nextera’s plugs form heat-tight, pressure-tight, and leak-tight seals with long life in severe environments such as power plants, refineries, and offshore platforms.

Key Features

• Leak-Tight Performance – Exhibits repeatable sealing of inspection ports to moisture infiltration and maintains the integrity of insulation
• High Temperature & Pressure Resistance – Built to endure extreme industrial conditions, including thermal cycling and system stress
• Tool-Free Installation – Simple plug-in construction that does not require special tools, preventing damage to insulation during installation or removal
• Multi-Material Variants – Available in stainless steel, aluminum, and silicone variants to address diversified environmental and functional requirements
• Cost-Effective & Reusable – Cost-saving with a long lifespan, best suited for repeated inspection cycles

Frequently Asked Questions

1. What are NDT inspection plugs used for?

NDT (Non-Destructive Testing) inspection plugs are designed to provide repeatable access points for inspecting insulated piping, vessels, and equipment without removing or damaging the insulation system. They are commonly used for CUI (Corrosion Under Insulation) monitoring and other mechanical integrity testing in refineries, power plants, offshore platforms, and chemical facilities.

2. What materials are Nextera’s inspection plugs made of?

Nextera inspection plugs are available in stainless steel, aluminum, and high-temperature silicone. Each material is selected for its corrosion resistance, durability, and suitability for specific environments, including marine, chemical, and high-temperature applications.

3. How do inspection plugs help prevent CUI?

By providing a sealed inspection port, NDT plugs prevent moisture ingress that can accelerate Corrosion Under Insulation (CUI). They allow maintenance teams to inspect and monitor equipment regularly while ensuring the insulation remains intact and leak-tight after reinstallation.

4. Are NDT inspection plugs reusable?

Yes. Nextera’s NDT plugs are designed for repeated inspection cycles. They can be installed and removed without special tools, making them a cost-effective, long-term solution for ongoing asset integrity monitoring.

5. In what industries are NDT inspection plugs commonly used?

NDT inspection plugs are widely used across industries that require strict mechanical integrity testing and corrosion monitoring, including:

• Oil & Gas (refineries, pipelines, offshore rigs)
• Power Generation (boilers, heat exchangers, pressure vessels)
• Chemical & Petrochemical plants
• Marine and offshore sectors
