In addition, the convenience and effectiveness of the various power tools play an important role in many sectors. A good example of this is the work in public infrastructure. The blasting of bridges, tracks and highways, among other things, is a very time-consuming and labor-intensive job, which is subject to a lot of pressure because of the time. When blasting these objects, workers are also exposed to various small particles and possible chemicals. With the use of the Bristle Blaster® and MBX® from MontiPower, abrasive blasting is a thing of the past.

10 types of abrasive blasting

There are several types of blasting methods, in this article we will tell more about the differences and different types of blasting methods.

Bristle blasting

The Bristle Blaster® and MBX® from MontiPower are the new developments in the field of surface preparation. Due to the specially developed technology with patented brushes, the power tools are the perfect alternatives for the existing blasting equipment.

With the use of the Bristle Blaster® and MBX® from MontiPower, blasting with different types of loose abrasives is a thing of the past for smaller areas and difficult to access areas. The tools are easy to use, are – unlike blasting – completely safe and very effective. Not only in cleaning surfaces, but also in processing them.
With their impact, the brushes of the power tools create a profile on the surface that can be compared to the surface profile that is created after blasting. In this way, MontiPower tools are the ideal alternative to sandblasting.

Bead blasting

Bead blasting has become an increasingly popular method of surface treatment. It is an effective and efficient method for removing dirt and oxidation from different materials.

There are various surface preparation techniques available to use and choose from. Abrasive blasting is the most well-know form of surface preparation. This method is often used for removing coatings, mill scale, paint and other dirt. In most cases, abrasive blasting involves applying air and an abrasive media with great force to the surface. This results in the removal of the material from the object. There are many different types of media to blast with. A few examples of blasting techniques with different media are: sandblasting, vapor blasting, vacuum blasting, wheel blasting and bead blasting. All these options have their own advantages and disadvantages. It this article, we will focus on bead blasting.

Centrifugal blasting

Centrifugal blasting is a type of surface finishing process where a metal surface is blasted by an abrasive material that is propelled by a centrifugal force. The process sprays the abrasive material onto the surface at a high velocity. This process is commonly used to remove scale, corrosion and burrs from a metal surface. In addition, it can be used to clean, roughen or texturize a surface or as a form of shot peening. Centrifugal blasting also provides a unique way to etch and debur surfaces. Many surface preparation projects may require manual cleaning if centrifugal blasting is not used.

Dry ice blasting

Dry ice blasting, or CO2 blasting is a technique of cleaning where solid CO2 is accelerated in a pressurized air flow and focused on a surface to clean it.

This technique is a very clean alternative compared to other blast cleaning methods. It can be used to clean surfaces. It is used to get rid of dirt, oil, paint, or strip pollutants from a surface. Dry ice blasting doesn’t cause contaminants to build up in the waste and dramatically lowers the secondary waste that needs to be thrown away.

Pencil blasting

Pencil blasting is a process of using a technique similar to “burning in” with a pencil-shaped brush. This type of blasting is often used as a way to get into areas of difficult access where heavier sandblasting is not recommended or possible. By choosing the correct material, size and shape of the media used in the process, it is possible to achieve clean, smooth finishes with minimal to no warping or crack damage. It is a common choice for the repair or blasting of raw metals, masonry, wood, plastic and other materials, as it is a more gentle and precise process than heavier blasting methods.

Sandblasting

Sandblasting involves blasting a combination of sand and air under high pressure onto the surface that has to be prepared or cleaned. Due to the high force with which the sand is applied to the surface, mill scale, dirt or any coatings are easily removed. Moreover, the sand creates a structure in the surface, which makes it easy to apply a new layer. However, despite its advantages, sandblasting also has a large number of disadvantages. For example, sandblasting is very dangerous to our health. But why is sandblasting actually so dangerous? And what are the risks?

Soda blasting

Soda blasting is a mild form of abrasive blasting using sodium bicarbonate particles and compressed air, which has a gentler effect than sandblasting.

Soda blasting involves the use of compressed air to blast particles of sodium bicarbonate with a much lower intensity than traditional abrasive blasting techniques, such as sandblasting. Soda blasting is a more gentle form of abrasive blasting. It is used to clean, strip and finish surfaces in which it causes less damage and doesn’t create hazardous substances or dust.

Steel grit blasting

Steel grit blasting is a process where metal is blasted with a small amount of compressed air and steel particles. This process can be used to clean, strip, and prepare surfaces before a fresh coat of paint or finish can be applied. The steel grit blasting process is a popular choice for many projects since it is both less abrasive and cost effective. Additionally, steel grit blasting is versatile and can be used on many different surfaces. This process is often used on metals, plastics, and wood. The steel grit blasting process is a quick and effective way to change the look of a surface by removing rust, old paint and any other contaminants that may have collected on the surface over time.

Vacuum blasting

Vacuum blasting is an abrasive blasting process that uses a vacuum to capture material during the blasting process. This process is gaining popularity in many industries due to its ability to reduce air pollution, dust, and other airborne hazards. Vacuum blasting is a dry process meaning that little or no media, cleaning agents, or water are used in the blasting process. Vacuum blasting works by using large amounts of vacuum pressure to capture the blasting media as the blasting takes place. The vacuum then filters, cleans and collects the blasting media, making it possible to reuse the same media for multiple jobs. Vacuum blasting is an effective and environmentally-friendly option for surface cleaning, paint and rust removal, and most other abrasive blasting applications.

Wet blasting

Wet blasting is a process used for the surface preparation of metals, plastics, or other materials. During this process, a high-pressure abrasive slurry is delivered to the surface. This slurry is composed of a mix of an abrasive (such as aluminum oxide or silicon carbide), water, and a detergent (which helps keep the slurry suspended and separates the abrasive debris from the surface being treated). The combination of the high-pressure stream and the suspended abrasive in the slurry blasts the surface, providing a superior surface finish that can be used for various finishes or preparation for powder coating or other processes. Wet blasting is a much more efficient process than dry blasting and produces less dust and debris, making it ideal for use in sensitive environments such as aerospace or electronics.

What is wheel blasting?

For preparing and cleaning steel surfaces, there are several methods that can be used. For example, there are different methods of abrasive blasting, which are often used for removing coatings, mill scale, paint and other dirt. This abrasive blasting is done in most cases in the same way. It involves applying a combination of air and an abrasive with great force to the surface, causing the material to separate from the object. The best known example of this is sandblasting, but also blasting with other abrasives such as glass, plastic or vapor blasting are possible. But there is another form of blasting that can be used for this purpose: wheel blasting.

How does wheel blasting work?

Wheel blasting is similar to the aforementioned other forms of abrasive blasting in many ways, but it also has a number of clear differences. Wheel blasting does not use air under high pressure to apply the abrasive to the steel object, but the abrasive is put in motion by means of a rotating wheel. Different types of abrasives can be used when preparing or cleaning steel with wheel blasting. Among them are blasting grit, corundum, glass and plastic.

The benefits of wheel blasting

Wheel blasting has several advantages over similar other forms of abrasive blasting. One of the main advantages of wheel blasting is its highly efficient operation. The abrasive applied to the surface by means of the rotating wheel is immediately picked up and reused during the preparing process. This initially reduces the consumption of the abrasive, but also means that less dirt remains at the end of the cleaning process. Another advantage of wheel blasting is that the force and speed at which the abrasive is applied to the object can be adjusted. This makes it easy to use the abrasive economically, but when necessary, with heavier soiling, a greater force can be chosen. In addition, wheel blasting machines are relatively fast and efficient in preparing steel surfaces compared to other forms of abrasive blasting.

The disadvantages of wheel blasting

Wheel blasting, in addition to the aforementioned advantages, also has a number of disadvantages. First of all, wheel blasting machines are in most cases for steel surfaces that are relatively flat. When there is a lot of unevenness, wheel blasting is less effective. Also, wheel blasting is not to be used with every type of surface. Due to the relatively high speed at which the abrasive is applied to the object, damage can quickly occur. For more fragile surfaces, e.g. vapor blasting will be preferred. Finally, the last disadvantage of wheel blasting: the maintenance costs. Given the fact that wheel blasting machines contain many mechanical parts, which can be easily damaged by the use of abrasives, these parts often require maintenance. This results in high maintenance costs, which makes wheel blasting a relatively expensive method of surface preparation.

Corrosion of steel pipelines

Corrosion of steel pipelines is a common process that is unfortunately difficult to counteract. To keep the condition of the pipelines intact, it is necessary to remove the corrosion in time. When the corrosion is more persistent, the choice is often made to replace the pipeline in its entirety. A demanding and also expensive job, costing billions of dollars per year worldwide.

There are various types of corrosion in pipelines. Each type has its own characteristics and ways to combat it. But what is corrosion exactly? How does corrosion occur in pipelines? And what are the different types of corrosion that we can distinguish?

What is corrosion?

Corrosion is a deterioration of metal as a result of a chemical process. This chemical reaction is caused by contact with various factors from the environment. Often corrosion is confused with rust. However, corrosion is a broader concept than corrosion. With rust, the deterioration of the surface occurs specifically through a reaction of oxygen in combination with damp. As a result, the well-known visible brown layer appears on the metal surface. With corrosion, this deterioration can be caused by a chemical reaction of several factors. There are various forms of corrosion in pipelines. But what are the most common types of corrosion in pipelines, and what characterizes these types of corrosion?

Oxygen corrosion

Oxygen corrosion is the other name for the already mentioned rust. It is the most common and also the most visible type of corrosion in pipelines. As mentioned, oxygen corrosion is caused by a chemical reaction between oxygen and water or another form of damp. From this reaction, a so-called oxide skin is formed, which we know better as the brown layer that attacks the metal surface. An important characteristic of the oxide skin of oxygen corrosion is the open structure of the layer. This ensures that oxygen and water continue to reach the surface easily, so that the steel will slowly but surely become completely corroded. For this reason, stainless steel or aluminum is used more often in various sectors; these materials have a denser oxide skin, which makes oxygen corrosion less likely to occur.

Uniform corrosion

Uniform corrosion is broadly comparable to oxygen corrosion. Uniform corrosion also results from a chemical reaction between damp and oxygen. This form is characterized by the – the name says it all – uniform distribution of the corrosion over the entire steel surface. Uniform corrosion is considered by many to be the least dangerous form of corrosion. By taking measurements or from previous experience, the speed and extent of corrosion formation can often be predicted well. As a result, the development and consequences of uniform corrosion can often be better estimated than those of other forms of corrosion in pipelines.

Acid corrosion

In the case of acid corrosion, the combination of acid and metal react together to form hydrogen gas and metal salt. To better understand this, it is good to first look at what is actually meant by acid. This has to do with the pH value of water. Normal drinking water has a pH value of between 7 and 9.5. Does the water have a pH value below 7? Then we speak of an acid. When this acid comes into contact with metal, corrosion occurs in the form of hydrogen gas and metal salt. The degree of corrosion depends on the tension of the material. Each material has its own voltage, which can cause a current to flow between several materials. If the voltage of the material has a lower voltage than hydrogen, acid corrosion occurs.

Galvanic corrosion

The voltage of metals that were briefly discussed in the case of acid corrosion also play a major role in galvanic corrosion. This type of corrosion can occur when two different metals are in close proximity to each other. If these metals come close together, in combination with water or a similar conductor, the reaction that is set in motion will result in corrosion. In this process, more corrosion will occur on the metal with a lower voltage than on the metal with a higher voltage.

Stress corrosion

Unlike, for example, oxygen corrosion, stress corrosion is very difficult to predict and only detect at a late stage. This form of corrosion occurs particularly with tension from within, for example with dents or welds. But this is not the only factor involved in stress corrosion. When the combination of chlorides, high temperatures and internal tension come together, stress corrosion will occur, and the material will crack. Whereas oxygen corrosion and uniform corrosion occur less quickly and frequently in RVS, stress corrosion occurs more frequently in RVS.

Stray current corrosion

Stray current corrosion is a form of corrosion similar to galvanic corrosion. Stray current is electric current that flows from a conductor back to the soil or surrounding environment. The difference from galvanic corrosion is in the fact that it is not the other metal, but the actual current from the conductor that causes corrosion to occur in the steel pipeline.

Pitting Corrosion

Pitting corrosion occurs in the oxide layer that may have developed in the steel pipeline. This form of corrosion occurs mainly in the areas where the oxide layer is damaged. In addition, pitting corrosion can also occur as a result of the incorporation of chloride ions or metal particles. The corrosion that occurs in the oxide layer causes small pits to form in the steel, but these are often barely detectable at first glance.

Crevice corrosion

Similar to pitting corrosion is crevice corrosion. In this case, the corrosion does not occur in damaged surface, but in cracks. When the surface comes into contact with a conductor and also makes electrical contact with the crack, crevice corrosion will occur. As with pitting corrosion, the corrosion will develop more and more strongly and the crack will become deeper and deeper.

Intergranular corrosion

Intergranular corrosion is one of the most insidious forms of corrosion. Due to the fact that this type of corrosion is molecular, it is not or hardly visible to the naked eye. On the surface of the steel pipeline, little or no corrosion occurs, but from the inside the material is increasingly corroded. This causes the metal to become increasingly brittle, which in turn causes the metal to lose its cohesion and may eventually cause major damage.

Microbial corrosion

Microbial corrosion is one of the most unknown forms of corrosion. Nevertheless, this form of corrosion is very relevant to steel pipes, as microbacterial corrosion is especially common in pipelines. This has to do with the fact that in most cases, the bacteria thrive in oxygen-free spaces. The corrosion is caused by the bacteria secreting a substance, which has a corrosive effect on the steel. Microbacterial corrosion is most comparable to acid corrosion, but in this case the corrosion is not caused by an acid but by the bacteria.
