Global NDT demand: which sectors are calling the shots?

How does your industry ensure the safety of your assets?

For many, Non Destructive Testing (NDT) is their go-to technique as the global NDT industry meets this demand. NDT refers to the testing of materials using non-invasive techniques, such as ultrasound. Flaws within the asset are revealed, allowing repairs and other actions to take place.  

As technology continues to advance, the demand for NDT services has experienced a significant increase. 

So, which industries are harnessing NDT and what role does the global NDT industry play in saving costs across these sectors?

In this blog, we’ll address these questions and discover why NDT has become an indispensable tool for many. 

Why is NDT used? 

NDT is used for many reasons, each contributing to the overall efficiency, accuracy, and safety of various industries. 

Here’s a breakdown of why NDT is extensively used:

Cost savings 

NDT stands out as a preferred choice over destructive testing due to its ability to subject the material or object under examination to scrutiny without causing any harm. This ensures the asset can continue to be used once repairs have taken place, which leads to significant cost savings. 

Time savings

Technology has allowed the quality of non-destructive inspections to improve significantly, meaning some tests can now take a fraction of the time. This reduces downtime for sites, meaning operations can get back to normal quickly. 

Accuracy assurance 

Proven for accuracy and predictability, NDT methods embody the essential qualities necessary for maintenance procedures aimed at securing personnel safety and ensuring the durability of NDT equipment.

Safety 

Almost all NDT techniques (except radiographic testing) are harmless to people.

Compliance with regulations 

NDT plays a crucial role in meeting regulatory requirements. By conducting thorough inspections and adhering to standardised testing procedures, industries can demonstrate compliance with local and international regulations, avoiding legal complications and reputational damage.

Now, let’s take a look at some of the industries where NDT plays a key role in inspection. 

Manufacturing

Surprisingly manufacturing accounted for the highest revenue share in NDT in 2022 globally, and this is set to continue. 

There is a high increase in the rate of manufacturing worldwide driving this increase.

Techniques such as visual inspection, dye penetrant testing, and radiography help manufacturers maintain high standards throughout the production process.

Oil and gas 

The oil and gas industry commands the next largest share. Despite the move towards renewable energy sources in many nations, globally, this sector shows no sign of slowing down. 

It faces numerous challenges in maintaining the integrity of its infrastructure. Pipelines, refineries, and drilling equipment operate in harsh conditions that can lead to corrosion and other structural issues over time. 

NDT plays a pivotal role in identifying and mitigating these problems before they escalate into catastrophic failures.

Eddy current testing, magnetic particle inspection, and phased array ultrasonic testing are among the NDT techniques employed to monitor the health of critical assets in the oil and gas sector. 

Other energy generation industries (such as Renewable energy) are the next biggest consumer of NDT services. 

Construction

Next comes the construction industry. 

NDT techniques such as ground-penetrating radar, ultrasonic testing, and infrared thermography are deployed to assess the health of structures without causing any damage.

The construction industry recognises the importance of preventative measures, relying on NDT to identify potential issues before they compromise the integrity of critical structures.

Aerospace

By no means insignificant is the work demanded by the aerospace sector.

With an increasing focus on lightweight materials and complex structures, the industry relies on advanced NDT techniques such as ultrasonic testing, radiography, and eddy current testing

These methods allow engineers to scrutinise materials without causing damage, ensuring that every inch of an aircraft or defence system meets stringent quality standards.

Moreover, the continuous development of new materials and the push for more fuel-efficient aircraft have fueled the demand for advanced NDT solutions.

NDT’s global odyssey

Worldwide, manufacturing emerges as the sector that demands the market share of the global NDT services. There is a huge increase in the rate of manufacturing globally, and this is driving demand. 

Whilst many countries are starting to shift their focus to renewable energy sources, there is no doubt that globally, oil and gas command the next largest share and whilst some analysts are suggesting the other energy industries will grow (and demand more NDT services in the future), it is clear that oil and gas are here to stay. 

One this is very clear – the need for NDT is huge! It is a thriving industry and there are plenty of opportunities for growth out there.
