Corrosion is a very common issue faced by the oil and gas industry. Pipelines, offshore platforms, storage tanks, and other processing facilities are constantly exposed to extreme environments, which will significantly increase the metal deterioration rate. Of all the strategies, abrasive blasting is the most important one in preparing metal surfaces for protective coating and other treatments.
Most companies often depend on products supplied by well-established garnet suppliers in UAE to get excellent surface preparation results to apply corrosion-resistant coatings. Accurate abrasive selection will go a long way in improving the adhesion of the coatings.
Corrosion Prevention in Oil & Gas Operations
Corrosion will cause damage to the structure, failure of equipment, expensive repairs, and downtime during operations. In sectors such as oil and gas, the smallest of corrosion issues will lead to serious safety hazards and environmental challenges.
Protective coatings are most commonly used on surfaces made of metal to protect them from corrosive elements that has moisture, chemicals, etc. However, the quality of the surface preparation process determines how effective these coatings can be. Coatings falling prematurely and lower ability to protect critical assets are the results of improper preparation.
Why Is Surface Preparation A Necessity?
Contaminants, including rust, dirt, old paint, mill scale, and other surface residues, must be removed before applying any type of protective coating. Abrasive blasting is known as one of the most effective methods to use to get a clean and fully prepared surface.
Many industrial facilities partner with steel shot suppliers in UAE to get access to high-quality abrasives that can clean metal surfaces with ease. A steel shot is mostly used in applications where consistency and dependability in surface cleaning are non-negotiable.
Efficient surface preparation is needed to create a perfect foundation for coating, as it provides stronger adhesion and improvement in resistance to corrosion over time.
Abrasive Blasting To Remove Surface Contaminants
Abrasive blasting is a process in which abrasive media are shot at a high velocity at a surface to remove unnecessary materials. This process is done to take off contaminants that will reduce the performance of the coating, as it'll expose a metal surface that is clean and ready for treatment. Benefits of the blasting process are the following:
- Removal of rust and corrosion products
- Elimination of old coatings and surface contaminants
- Improved adhesion of coating
- Better surface uniformity
- Increased long-term corrosion resistance
Why Does Surface Profile Creation Matter?
Along with having a clean surface, the process of abrasive blasting will also create a surface profile that makes the coat bond in a more effective manner. The profile includes very minute peaks and valleys that will provide more adhesion for protective coatings. To increase the life length of the coating and to decrease the chances of premature coating failure, a properly prepared surface is needed. It is very important to have the correct surface profile, especially in environments where the materials are in contact with moisture, chemicals, salts, extreme temperatures, etc.
Select the right abrasive material to achieve the desired surface finish and performance needs for the operations.
Choosing Abrasives Based On Applications
All projects can't be performed with the same type of media. It can vary depending on the coating specifications and operating conditions. Features to be considered here during the selection of abrasives include particle shape, hardness, recyclability, and cleaning efficiency.
Many industries source from steel grit suppliers in UAE for applications that need deeper cleaning and surface profiling. Steel grit is the most commonly used abrasive media for when there is a need for a tougher surface profile to aid in the adhesion of heavy-duty industrial coatings.
Match the abrasives to the specific project requirements. This will significantly increase the efficiency of the blasting process as well as result in better corrosion protection outcomes.
Strengthening Oil & Gas Infrastructure
Abrasives are important in providing corrosion resistance across various industries, especially oil and gas infrastructure, as they remove contaminants to create a perfect surface profile to apply protective coatings. Work with only certified abrasives suppliers in UAE, like BlastCore MiddleEast LLC, to help find the needed abrasives that will allow the business to be able to achieve excellent surface preparation and a proper finish that can last for a long time.
