Process fluids are essential products used to optimize industrial processes. Water, steam, oil, compressed air, exhaust gases, etc.: a process fluid can take many forms depending on the industry and the machinery involved. From the food processing industry to the chemical industry, including the cosmetics and pharmaceutical sectors, process fluids are used in a wide variety of industries.

These fluids are often particularly corrosive, which is why they require the construction of a dedicated system. This also means carefully selecting certain components; they may be single- or double-walled, with varying levels of finish quality on the interior and exterior, such as the liner tubes, which must be made of resistant materials.
