Product Features
1. Anti – Rust Treatment
We provide two types of anti – rust treatments: hot – dip galvanizing and electro – galvanizing.
- Hot
Dip Galvanizing: This process forms a thick, uniform zinc coating on the surface of the slewing ring. It provides excellent corrosion resistance, especially in harsh sewage treatment environments where chemicals and moisture are prevalent. The hot – dip galvanized layer can effectively prevent rust and corrosion for a long time, ensuring the slewing ring’s structural integrity.
- Electro
galvanizing: It offers a smooth and precise zinc coating. While being thinner than hot – dip galvanizing in some cases, it still provides good anti – rust protection, especially suitable for parts that require relatively high precision and a more aesthetically pleasing surface.
2. Application in Sewage Treatment
Sewage treatment plants are full of corrosive substances such as sewage, sludge, and various chemicals. Our anti – rust slewing rings, manufactured by ZZ MANUFACTURING CO LTD, can withstand these harsh conditions. They are used in equipment like sewage treatment tanks, where the slewing ring enables the rotation and movement of components for mixing, stirring, and sludge removal. The anti – rust property ensures that the slewing ring can maintain normal operation for a long time without being damaged by corrosion, reducing maintenance frequency and costs.
- Market Response
German and Russian customers have shown great enthusiasm for our products from ZZ MANUFACTURING CO LTD. In Germany, where engineering and quality standards are extremely high, our slewing rings meet their strict requirements for durability and anti – corrosion.
