There are many applications of wear-resistant ceramic elbows in power plants, mainly used to solve the abrasion phenomenon of coal powder preparation and transmission system pipelines in coal-fired power plants, so what are the common types of wear-resistant ceramic elbows in power plants?
1, centrifugal casting composite wear-resistant ceramic elbow
Centrifugal casting wear-resistant ceramic elbow is a wear-resistant ceramic elbow made by "self-burning high temperature synthesis - high speed centrifugal technology", forming a uniform, dense and smooth surface ceramic layer and transition layer at high temperature and high speed. In addition, working at normal temperature 850 ~ 900 degrees ceramics will not fall, light weight, composite ceramics with hardness anti-wear, to solve the past with thickness anti-wear. At present, straight pipe, elbow, elbow, tee and so on in the industry with serious wear effect is very good.
2, full name ceramic lining ceramic elbow
Wear-resistant ceramic elbow gives full play to the high strength of steel pipe, good toughness, impact resistance, good welding performance and corundum porcelain high hardness, high wear resistance, corrosion resistance, heat resistance, to overcome the characteristics of low hardness of steel pipe, poor wear resistance and poor toughness of ceramic. Therefore, wear-resistant ceramic elbow has good wear resistance, heat resistance, corrosion resistance and resistance to mechanical and thermal shock, good weldability and other comprehensive properties. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, corrosive media, etc.
3, patch wear-resistant ceramic elbow
The patch wear-resistant tube is an alumina ceramic sheet pasted on the inner wall of the pipe with adhesive. The production process of this product is simple and the production cycle is long. The operating environment shall not exceed 150 degrees.
4, spot welding card wear-resistant ceramic elbow
The spot welding jammed wear-resistant pipe is to paste the alumina ceramic sheet with a hole in the middle on the inner wall of the pipe with high temperature resistant strong adhesive, and at the same time, the ceramic is solidly welded on the inner wall of the steel pipe through the small hole with the spot welding process. To protect the solder joints, a ceramic cap is added to the top. The production process of this kind of product is relatively complicated, the production cycle is long, and the cost is high.
