Industrial boiler inspections are an essential part of the lifecycle of an asset in the Energy From Waste (EfW) industry. 

Ensuring that boilers are functioning efficiently and safely is crucial, but these inspections can often be costly and time-consuming. 

How can you make them more cost-effective? 

Here are some cost-saving tips for effective industrial boiler inspections that incorporate advanced techniques and smart strategies.

Importance of industrial boiler inspections 

Industrial boiler inspections are crucial for ensuring the safety, efficiency, and longevity of boilers. 

These inspections help identify and address potential issues before they escalate into major, costly problems, thereby preventing unexpected breakdowns, reducing downtime, and extending the lifespan of the equipment. 

Regular and thorough inspections also ensure compliance with safety regulations, optimise operational performance, and safeguard against hazards, making them an indispensable part of maintaining and managing industrial boiler systems.

At NDT Group, we regularly perform boiler inspections utilising our team of experienced technicians. Here’s how we make sure they’re cost-effective:

Leverage borescopes for internal inspections

Firstly, we use borescopes. These are valuable tools for conducting internal inspections of boilers without the need for extensive disassembly. 

These flexible, camera-equipped devices can navigate through tight spaces and provide high-resolution images of the internal components.


Minimised Downtime: Inspections with borescopes are quick and can often be done without shutting down the entire system.

Detailed Imaging: High-quality images help in accurately diagnosing issues within the boiler.

Reduced Labour Costs: Fewer personnel are needed since the inspection is less invasive and quicker.

Implement IRIS inspections

Internal Rotary Inspections Systems (IRIS) involve using rotating equipment to thoroughly inspect the inner walls and tubes of a boiler. 

This technique is highly effective in identifying corrosion, scaling, and other forms of wear and tear that can affect the boiler’s performance.


Comprehensive Coverage: Rotary inspections provide a 360-degree view of the internal surfaces, ensuring no area is overlooked.

Early Issue Detection: Identifying problems early on can prevent more significant, costlier repairs later.

Efficient Process: These inspections can be completed relatively quickly, reducing downtime.

Utilise radiography for non-destructive testing

Radiographic testing, or radiography, uses X-rays or gamma rays to inspect the internal structure of the boiler. 

This non-destructive testing method can reveal hidden defects such as cracks, voids, or inclusions without causing any damage to the boiler itself.

Our building in Sandycroft is home to our Radiography Bay. We are able to bring assets to our site and conduct inspections in-house, ensuring you can focus on your site operations without interference. 


Non-Invasive: Radiography can detect internal flaws without the need to dismantle the boiler.

Accurate Diagnostics: Provides precise information about the condition of internal components.

Cost-Effective: Reduces the need for exploratory dismantling and potential subsequent repairs.

Regular pipe inspections

Inspecting pipes regularly is crucial as they are integral to the boiler’s operation. 

Over time, pipes can suffer from corrosion, scaling, and other forms of deterioration that can lead to leaks or reduced efficiency.


Preventative Maintenance: Regular pipe inspections help in maintaining the overall health of the boiler system.

Extended Lifespan: Addressing pipe issues early can prolong the life of the boiler.

Enhanced Safety: Regular inspections ensure that pipes are functioning safely, reducing the risk of catastrophic failures.

Strategic planning and scheduling

Effective planning and scheduling are crucial for minimising costs. 

Coordinate inspections with production schedules and other maintenance activities to reduce downtime and ensure efficient use of resources.


Reduced Downtime: Scheduling inspections during low production periods minimises operational impact.

Efficient Resource Use: Aligning inspections with other maintenance tasks ensures all necessary work is done simultaneously, reducing repeated shutdowns.

Improved Budget Management: Spreading inspection costs over time helps in better budget allocation and management.

Industrial boiler inspections

Cost-saving tips for effective industrial boiler inspections are essential for maintaining the efficiency and longevity of boilers in the EfW industry. 

By utilising advanced techniques such as borescopes, rotary inspections, radiography, and regular pipe inspections, you can significantly reduce the costs associated with these critical inspections. 

Implementing these strategies not only saves money but also enhances the safety, reliability, and performance of industrial boilers, ensuring they continue to convert waste into energy efficiently and effectively.

At NDT Group, we use borescopes, rotary inspections, radiography and other techniques to carry out industrial boiler inspections, as part of our AIM services.
