Power Plant Inspection Services

Power plants require in-service inspections and non-destructive examinations to ensure that they are operating properly. There are many moving parts, high temperatures, and different dirt concentrations that coal-fired power plants must endure. This can be costly, but advances in asset optimization and predictive maintenance have made the cost of maintaining coal-fired plants stable through 2035.

In-service inspection

In-service inspection services for power plants are a key element of maintaining the health and safety of a power plant. They can be conducted at intervals ranging from a few years to approximately ten years. The inspection intervals depend on the component under inspection and its accessibility. Some systems may be inspected more frequently than others.

In-service inspection services contribute to the continued safe operation of nuclear power plants (NPPs), preventing component or equipment failures and increasing confidence in the continued safety of the plant. Detailed provisions are outlined in the safety guide, which describes the inspection methodology, responsibilities, and access arrangements. The guide also outlines the inspection techniques and personnel qualifications. The inspection process also involves documentation, evaluation of the results, and repair of non-conformances.

Non-destructive examination

Non-destructive examination is an important part of power plant inspection services. It allows plant owners and operators to identify critical components in a fast and efficient manner. The results of the examination can be used to guide maintenance and operations decisions. In addition, these services can prevent life-threatening situations, such as a plant explosion, from happening.

Non-destructive testing and evaluation services are essential to the safety and reliability of power plants, refineries, pipelines, and trains. The techniques used in these services are highly accurate and do not require shutting down any equipment. These services are performed using specialized tools.


Drones are a great tool for power plant inspection services. They can be used in hazardous environments, such as nuclear power plants, where human inspectors often face dangers from radiation. These drones can safely fly in these environments, collecting visual data that would otherwise be impossible to collect manually.

There are many uses for drones in power plants, from one-off inspections to yearly history assessments. In addition to identifying unexpected problems, drone inspections are a great way to compare equipment condition over time. Drones can inspect various areas of a power plant, such as the firing duct. They can inspect cracks in burner nozzles and baffles, as well as look for changes in crack size or location since previous inspections.


Power plants require frequent maintenance and inspection. ECT is an effective technique for identifying defects and reducing inspection time. The technology is also effective in identifying flaws in metals and alloys. It can also determine the corrosion state of different components. ECT services are beneficial in both new and existing power plants.

Eddy current testing uses sophisticated software and detection probes to detect minute flaws in materials. It can scan both subsurface and surface levels. However, this technology has its limitations. For instance, it cannot probe as deeply as ultrasonic testing instruments. This is why companies need to weigh the pros and cons of this technology.


PAUT power plant inspection services use advanced technologies to detect structural flaws in power plants. These advanced technologies allow the inspection of many different areas and are more accurate than conventional methods. With a PAUT probe, you can see the details of an entire area in a few minutes rather than hours or days. This technology uses multiple transducers to scan more areas of an object during the inspection. Furthermore, it uses computer-controlled software to optimize test parameters. Consequently, your inspections will be much more reliable.

PAUT is different from other nondestructive testing (NDT) techniques because it does not require shutdowns, which significantly cuts down on inspection time. It can also be used to inspect complex geometries. Additionally, its phased array probe has the ability to control the shape and direction of the beam, which enables a better coverage of the entire area. In addition, its digital feedback helps you identify flaws and determine weld quality.
