应用:
Since ceramics have excellent hardness and strength, FUVALVE 开发 ceramic lined Elbows, which are
widely used in many highly corrosive and abrasive transmission systems especially for coal fired power plants,
钢铁厂, 矿业, 化学工业, 石化, 多晶硅与冶金.
The following working conditions are some typical medium in which ceramic lined elbows have been proved to have
good performance.
- Coal powder
- 硅粉
- Fly ash
- Mining slurry
- Mining Slag
- 洗煤
- Strong acid slurry
- Paper making Slurry
