The Materials Of Flottweg Centrifuges
The components of Flottweg centrifuges that come into immediate contact with the medium to be processed (e.g. bowl, scroll and feed) are exclusively made from high-quality, rust and acid-resistant stainless steels. This means increased strength and improved durability are possible.
Materials made from high-quality stainless steel centrifugal casting
In order to guarantee a perfect process from the decanter centrifuge in spite of the high rotation speeds, forces and temperatures, decanter bowls are produced using duplex centrifugal casting and decanter scrolls using stainless steel centrifugal casting.
High-quality Flottweg materials and their advantages
- Increased durability of the decanter centrifuge, even when confronted by aggressive media (acids, alkalis and cleaning agents)
- Maximum product quality during the entire process
- Improved stability of the decanter centrifuge
- Depending on the application, Flottweg offers the appropriate materials for your centrifuge
Flottweg components are produced from high-quality, rust and acid-resistant stainless steels
Stainless steel is a steel alloy containing chrome. Corrosion resistance is one of the most important properties of stainless steel. The minimum content of chromium is 10.5%, the maximum amount of carbon is 1.2%.
Austenitic stainless steel is the most widespread type of stainless steel. The high corrosion resistance, excellent forming capability, good suitability for welding and increased toughness reflect the reasons for using austenitic stainless steel.
Duplex steel combines the advantages of austenite and ferrite. The high corrosion resistance, good toughness, improved strength and outstanding durability are ideal for decanter centrifuges.
Nickel-based alloys are alloys that have a higher proportion of nickel than other elements (chromium, iron, molybdenum or copper). This means it is possible to manufacture many different alloys.
Materials – the Flottweg centrifugal casting process
Flottweg decanter bowls are exclusively manufactured using the centrifugal casting process. In this case, molten steel hardens in the centrifugal field, meaning that it has an even structure and high strength. Manufacturing using this process produces other significant features. For example, the centrifugal casting process is far superior to static casting in many areas. What is more, the centrifugal casting process has properties that are equivalent to forging quality.
