What is Tank and Installation Passivation Service?

Tank and installation passivation service is an important process applied in industrial sectors, especially to ensure long-lasting, safe and efficient operation of metallic surfaces. This process generally aims to protect tanks, pipelines, boilers and other metal installation elements from corrosion, rust and chemical effects. By creating a protective layer on metal surfaces, the metal is made more resistant to external factors. Passivation strengthens the naturally occurring protective layer, especially in materials such as stainless steel, and increases the resistance of these materials to environmental influences.

Passivation process is of great importance for tanks and installations to operate safely and efficiently in all kinds of uses. This process ensures that metal surfaces are covered with a protective layer as a result of chemical reactions. This layer prevents the metal from rusting, corroding and being affected by environmental factors. Passivation also helps metals gain a better aesthetic appearance.

How is Passivation Done?

The passivation process generally consists of four main steps: cleaning, acidic solution, passivation and final rinsing. Each of these steps ensures that the surface of the metal used during the process is properly protected and the passivation layer is formed properly.

Cleaning

Before starting the passivation process, it is very important to clean the metal surface. Because dirt, oil, oxide and other contaminants on the metal surface can reduce the effectiveness of the passivation process. The cleaning process ensures that the metal has a smooth and clean surface so that the passivation layer can form properly. Cleaning is usually done with chemical solvents or abrasive methods. In this step, the metal surface is completely cleared of external factors.

Passing through Acidic Solution

After cleaning, the metal surface is passed through an acidic solution. This step cleans the oxidized substances on the metal surface and helps remove dirt on the metal. The acidic solution usually contains nitric acid or hydrochloric acid. These acidic solutions destroy the oxide layers on the metal surface and make the surface smooth. Correct application of the acidic solution is critical to the success of the passivation process.

Pacification

The metal surface, cleaned from the acidic solution, is immersed in a special solution prepared for the passivation process. During passivation, a thin oxide layer forms on the metal surface. The passivation process helps the metal create a protective barrier against external factors. Especially in materials such as stainless steel, this thin oxide layer provides a high resistance to corrosion. The passivation process is usually done with oxidizing compounds, and as a result of the reaction, an anti-corrosion protective layer is formed on the metal surface.

Final Rinse and Drying

After the passivation process is completed, the metal surface is rinsed with plenty of water to remove acidic solutions. This step is necessary to ensure that the passivation layer does not deteriorate and the acidic solution does not remain on the metal surface. The metal surface must be rinsed thoroughly and then dried. The drying process is usually done with air and it is ensured that the metal is not left with water droplets. This stage is the last step of the passivation process and ensures that the surface is completely ready.

Benefits of Passivation

Tank and installation passivation has many important benefits. These benefits are valuable both economically and operationally.

Protection Against Corrosion

The biggest advantage of passivation is that it provides anti-corrosion protection to metal surfaces. The oxide layer formed on the metal during the passivation process makes the metal more resistant to environmental factors. In particular, water, acidic substances or other chemical factors can cause the metal to rust or corrode over time. Passivation protects the metal against such external factors and increases the durability of the metal surface.

Long Lasting Use

Passivation increases the durability of metal surfaces, ensuring long-term use. Tanks, pipelines and other installation elements wear and deteriorate less thanks to passivation. This reduces maintenance costs and allows installations to operate efficiently for longer. Since the durability of the metal surface increases, the life of such installations is also extended.

Cleaning and Hygiene

Passivation makes metal surfaces cleaner and more hygienic. Dirt and residues that are more difficult to clean can be more easily removed from metal surfaces thanks to the passivation process. Passivation is of great importance, especially in areas where hygiene is critical, such as the food and pharmaceutical industries. This process provides the cleaning required to produce products safely and healthily.

Aesthetic Appearance

Passivation allows metal surfaces to have a more aesthetically pleasing appearance. Especially in materials such as stainless steel, after the passivation process, the roughness on the surface decreases and the brightness increases. This is useful for visually important applications.

Protection from Environmental Effects

The passivation process makes the metal more resistant to environmental factors. Corrosion on metal surfaces can cause the release of harmful substances into the environment. Passivation prevents these harmful effects and offers an environmentally friendly solution. Additionally, less wear on metal surfaces helps preserve natural resources.

Usage Areas of Tank and Installation Passivation

Tank and installation passivation process is widely used in many industries. In these industries, passivation plays an important role to ensure safety, durability and efficiency.

Chemical Industry

In the chemical industry, especially tanks and pipelines where chemicals are transported and stored, need passivation process. Rapid corrosion may occur on metal surfaces under the influence of chemicals. Passivation ensures the long life of such installation elements and contributes to the safe operation of businesses.

Food and Pharmaceutical Industry

In sectors such as food processing and pharmaceutical production, hygiene and cleanliness are of great importance. Passivation keeps installations clean and helps maintain the quality of the products. Stainless steel tanks and pipelines, in particular, are widely used in these sectors, and passivation eliminates the risk of corrosion and ensures that healthy production processes continue.

Oil and Gas Sector

Since tanks and pipelines used in the oil and gas industry operate under extreme temperatures and pressure, the passivation process provides important protection. Passivation increases the resistance of such installation elements against corrosion and ensures safe operation of the system.

Energy Sector

Similarly, in the energy sector, pipelines and other metal installation elements are protected by passivation. This prevents corrosion that may be encountered during energy production and ensures that energy production processes continue uninterrupted.

Tank and installation passivation service is an important process that ensures long-lasting, safe and efficient operation of metal surfaces. Passivation eliminates the risk of corrosion on metal surfaces, making installation elements more durable. This service is of great importance especially in the chemical, food, pharmaceutical, energy and petroleum sectors. Passivation is not only economically beneficial, but also provides protection from environmental factors.
