Types of Power Plant Inspection Services

There are many types of inspection services that are available to power plants. Some of these include flyability inspection, ultrasonic guided wave testing, and eddy current testing. Knowing which of these is right for your plant is essential. It is important that these services include information on the critical components of your plant.

Nondestructive testing

Nondestructive testing (NDT) services for power plants can be an important part of an inspection process. These services can identify potential problems and suggest appropriate solutions. A well-run, systematic inspection can also help plants make better decisions about maintenance and repair activities. If an issue is detected during an inspection, a quick repair may be necessary to prevent a costly breakdown.

Nondestructive testing involves using a variety of techniques to evaluate a range of materials and components. These tests can also be used to evaluate the integrity of entire process units. These techniques are safe for both human operators and machinery and can help prevent injuries. In addition, NDT is cost-effective and repeatable.

Eddy current

Eddy current is a method that is used to inspect heat exchangers and other heat-transfer systems. It works by detecting leaks in the tubes of a heat-transfer system. These leaks can be caused by internal or external corrosion, erosion, mechanical impact, or cracking under stress. Heat exchangers also can fail because of failures in the expansion phase. An electromagnetic Eddy current can help detect these leaks.

The sensitivity of eddy current tests depends on a number of factors, including the conductivity of the material. For instance, a higher conductivity material is more sensitive to eddy currents than a low-conductivity metal. The test frequency also influences the data collected. Higher test frequencies increase near-surface resolution but limit the depth of penetration. Other factors that affect eddy current inspection are coil size, fill factor, and tube cleanliness.

Ultrasonic guided wave testing

Ultrasonic guided wave testing is a powerful and accurate method for analyzing and detecting cracks and other damage. The tool sweeps through the full frequency range in one single shot and allows for fast data acquisition and analysis. Trained operators use sophisticated software to analyze signals. In some cases, it is possible to acquire images in different directions, such as through buried pipe or high attenuation.

Ultrasonic guided wave testing is used in different fields. Its applications include measuring thickness, characterization, and flaw detection. It is not mandated by law, but the techniques used are governed by codes and standards. For example, the ASME Boiler & Pressure Vessel Code is a requirement for assessing the condition of pressure vessels.


Flyability offers a variety of services that help clients with routine plant inspections and monitoring. These services are designed to increase safety and efficiency and reduce costs. For example, Flyability drones can enter confined spaces in place of human inspectors, reducing downtime and risk. Flyability’s drones are collision-tolerant and can collect visual data in any confined space.

The Elios 3 drone is the company’s flagship drone, equipped with a LiDAR sensor for 3D mapping indoors. This capability allows inspectors to visually inspect assets during the inspection flight and to build survey-grade 3D models post-flight. Flyability will use its Series C funding to further cement its position as a market leader and develop new sensing and autonomous capabilities.
