Passivation is a chemical process whose purpose is to improve durability by causing one material to become inert with respect to another (for this reason, the process is also referred to as “inertization”). Its uniqueness lies in the fact that it is carried out in air. At the end of the passivation process, a transparent oxide layer is formed. Passivation is performed when there is a need to protect aluminum from oxygen oxidation, to protect iron-based materials from various harmful substances, and more.
Stainless steel passivation is one of the most in-demand services in the field. It is a chemical process that improves the resistance of stainless steel to various hazards, first and foremost corrosion—which, as is well known, can develop through oxidation processes. Passivation למעשה removes the free iron component from the stainless steel alloy without changing the properties or dimensions of the component. This action grants stainless steel a high resistance to corrosion, significantly extending its service life and potentially saving users considerable time and money. This service is particularly common in the food industry, pharmaceutical manufacturing, cleanroom equipment, piping systems, and more.
The passivation process requires extensive knowledge and the use of appropriate equipment and materials in order to achieve optimal results. For this reason, it is highly important to choose a company that performs the work meticulously and to ensure it has the experience, expertise, and tools necessary to carry out the process properly and achieve the best possible outcome.

The company offers a wide range of services to industrial plants, thanks to the use of advanced technologies and a strong focus on skilled human capital. You can rest assured that the company is fully equipped to perform the process in the most thorough and high-quality manner possible.
Client: A well-known winery in southern Israel.
The problem:
Sixteen new stainless steel tanks intended for the wine production process were exposed to seawater during transportation to Israel. As a result, corrosion began to form on both the external and internal surfaces of the tanks.
The solution:
A combined treatment for both the external and internal surfaces, including chemical cleaning to remove corrosion and passivation to create a protective layer.
Benefit to the client:
Restoring the tanks to regular operation within a short timeframe, through professional execution in accordance with strict international standards and with full adherence to safety requirements.
