It is very important to ensure the safety and functionality of equipment in modern industries; if not, it can have significant consequences in terms of downtime and failure costs. Industrial non-destructive testing has a key role in this. It enables companies to look at and assess materials without damaging them. However, does it really pay off? Knowing both the pros and cons of non-destructive testing will help you make your decision. 

In this detailed blog post, we will cover the basics of NDT testing, its types in brief, advantages and disadvantages in detail. Keep reading!

What Is Industrial Non-Destructive Testing?

Industrial non-destructive testing is a group of inspection methods which are employed to determine the health of materials, parts or systems without causing any harm. This also leaves the equipment in perfect working order, making NDT extremely efficient in the modern performance-centric industrial world.

NDT uses advanced technologies to identify defects both in and on the surface of a material. These techniques can be used to detect problems such as cracking, corrosion, and weak structures before they turn into major issues. 

These are the most popular techniques:

• Ultrasonic Testing (UT): Sound waves reflect off any defect and provide information about the location and size of the defect.
• Radiography Testing (RT): X-rays or gamma rays are used to record properties of internal discontinuities, like a medical scan.
• Magnetic Particle Testing (MPT): Visible particles are attracted to surface cracks in ferromagnetic materials by a magnetic field.
• Visual Inspection (VI): Experienced personnel do a visual inspection of accessible surfaces for wear, corrosion, or structural issues.

The main purpose of NDT is to ensure safety and prevent failures. The early detection of defects enables businesses to prevent failures and ensure they stay compliant. Industries can apply efficient inspection strategies with the help of advanced tools and proven inspection methodologies.

Advantages of Non-Destructive Testing

 Non-destructive testing has the following advantages:

1. No Damage to Materials

The first benefit of non-destructive testing is that it is not destructive. Parts are not damaged and can still operate. This is especially beneficial for critical industrial assets whose downtime can significantly hamper production.

2. Cost-effective in the long run

The benefits of non-destructive testing become evident when you consider what you’re trying to avoid: unplanned downtime, emergency repairs, and catastrophic failures. While there may be initial costs, NDT will avoid large failures that result in costly repairs or replacements. The early detection of problems means that businesses can save a lot on maintenance and downtime costs.

3. Ensures Safety and Compliance

The ability to detect hidden defects that cannot be seen from the outside is one of the advantages of NDT. This guarantees equipment safety and compliance with regulations in the industry. Compliance is more reliable and efficient with Bioscan Ltd, a leading NDT testing service provider.

 4. Minimal Downtime

There are numerous NDT techniques that do not require operations to be shut down. This minimises production losses and helps to maintain uninterrupted production which is essential in industries where uninterrupted production processes are required.

 5. Versatile Across Industries

NDT can be used for all types of equipment and most sectors, such as silo tank, spray dryer systems, cyclones and bag filter systems. This versatility makes it a favoured inspection technique for total industrial maintenance.

Disadvantages of Non-Destructive Testing

1. High Initial Equipment Cost

The drawback of non-destructive testing is the high cost of advanced equipment. Some technologies, such as radiographic and ultrasonic testing, require substantial capital investment and can be beyond the reach of some businesses. That’s why sometimes working with a specialist NDT testing service provider such as Bioscan Ltd is much more cost effective than developing a capability in-house.

2. Requires Skilled Professionals

NDT is a dependable and skill-based approach which requires training and certification of the technicians to ensure reliable results. Often the drawbacks of non-destructive testing will be related to the operator, not the test itself.

3. Limited Detection in Some Cases

A single NDT technique cannot be used to identify all defects. Depending on the method used, some weaknesses can be concealed, and multiple testing methods are necessary to achieve accurate results.

4. Interpretation of Results Can Vary

The results of the NDT might need special interpretation. The misinterpretation may result in wrong conclusions about the condition of the equipment. Bioscan Ltd, a leading NDT company, has highly skilled professionals who minimise these interpretation mistakes to nearly zero due to continuous exposure and the high number of clients served. 

5. Surface Preparation May Be Needed

Some NDT techniques need surface preparation and/or cleaning prior to testing. This increases the time and effort required for inspection and is required for accurate results.

Applications of NDT in Industrial Equipment

1. Silo Tank Inspection

NDT is often used to inspect silo tanks for cracks, corrosion and structural weaknesses. This contributes to the safety of storage and material loss prevention.

2. Spray Dryer Inspection

NDT can be used to detect wear, heat damage and internal defects in spray dryer systems, which can impact the system’s performance and efficiency.

3. Cyclone and Bag Filter Inspection

Routine cleaning of cyclone and bag filter units is necessary to maintain their ability to filter, identify blockages and avoid operational problems.

4. General Industrial Equipment

In addition to pipelines, pressure vessels, and storage tanks, NDT is applied to a wide variety of other equipment. Through their NDT services, Bioscan Ltd make sure that industries have full reliability and safety of their equipment.

Silos play a key role in the industrial sector when it comes to containing materials such as grains, cement, and chemicals. Structural faults such as silo cracks affect both their efficiency and performance. To maintain the integrity and efficiency of silos in the long run, it is imperative that one finds out what triggers the formation of cracks in silos. With the expertise and services offered by Bioscan Ltd., industries can anticipate problems and avoid costly damages that result from silo cracks.

What Are Silo Cracks?

Silo cracks are structural cracks which can occur in the walls of silos because of stress, environmental influences or construction. The severity and appearance of these cracks will differ from place to place, and their effect on the stability of the structure will differ.

There are several types of silo cracks:

• Hairline Cracks: These cracks may occur on the surface and can get worse over time if left untreated.
• Structural cracks: Deep, which ultimately effect on bearing capacity
• Vertical and horizontal cracks: Usually appear when there are stress or stability issues with the foundations.

Leaky silos are an issue even at a small scale, as imperfections in the construction allow the entry of water and other undesirable materials, which could degrade the condition of the silo and its contents. Getting a professional inspection from companies like Bioscan Ltd can spot these problems early and help fix them.

What Causes Silo Cracks? 

1. Poor Design and Construction

Most of the problems related to the silos are due to poor construction techniques. In case the structural design is not sound, the loading is not done properly, or even the quality of materials is poor, then stress will not be uniform. It results in crack formation.

 2. Uneven Foundation Settlement

Damage caused by silo foundations is a significant cause of damage to silos. If the foundation of the silo moves or subsides unevenly, it puts stress on the silo. This frequently leads to cracking in the storage silos, either vertically or diagonally, especially in large storage silos.

3. Thermal Expansion and Contraction

Temperature changes also cause materials to expand and contract. Over time, repeated heating and cooling can lead to structural degradation in steel and concrete silos, with visible cracking and failures at joints.

 4. Overloading or unbalanced material distribution.

The internal pressure may be high when the material is loaded more than the amount that the silo can hold or when the material is not loaded evenly inside the silo. When this imbalance happens, it creates stress in certain areas, which results in cracks and structural failure.

 5. Moisture and Corrosion

A problem with silos is water ingress. Water can permeate the concrete, contributing to cracking and reducing the durability of the concrete over time by causing corrosion of the reinforcement steel. Frequent surveys conducted by Bioscan Ltd can detect early moisture damage.

6. Poor Maintenance Practices

Small cracks can lead to big structural issues if they aren’t addressed immediately and inspections are not performed regularly. Inadequate repairs can result in greater expenses and safety hazards.

7. Environmental and External Factors

Due to structural stress and cracking caused by external stressors such as high winds, earthquakes, construction vibrations, and accidental impacts.

Risks Associated with Cracks in Silos

A crack in a silo is not only a structural problem but also a potentially dangerous one with regard to safe and efficient operation. Structural failure is perhaps the most dangerous and could lead to a complete collapse if cracks are not repaired. Cracks also allow for contamination, diminishing the quality of stored materials.

Additionally, leakage and material loss can impact productivity and profitability. The cost of repair is a lot higher if it is not attended to early. Mainly, cracks pose a safety risk for workers who work near or around the silo. Bioscan Ltd can effectively reduce the risks through regular inspection and timely repair services.

How to Prevent Silo Cracks

Silo cracking can be prevented by applying the following methods:

1. Regular Maintenance of Silo Tank

Regular checks enable early damage to be identified. Small cracks can be a sign of a bigger problem, so it’s important to address them quickly.

2. Proper Design and Quality Construction

Quality materials and engineering best practices provide long life. Stress points in the structure can be reduced by proper design.

3. Load Management and Monitoring

Do not overfill and spread material evenly in the storage unit. Use of internal pressure to keep the structure balanced.

4. Protective Coatings and Moisture Control

Protective coating prevents water intrusion and corrosion. The life of silos can be greatly prolonged by moisture-control measures.

5. Use of Advanced Monitoring Systems

Structural health monitoring systems can now provide information on the conditions of the silo in real-time, which is useful for monitoring stress and damage. Industries can effectively employ preventive measures with the help of Bioscan Ltd.
