Chemshun Ceramic Raching Ring Introduction (Al2O3: 17~23%)
1: Brief Introduction :
Raschig ring is an artificial filler earliest industrial use. Usually made of ceramic or metal sheet having a height equal to its diameter, the size of conventional 25mm ~ 75mm (also as small as 6mm, large up to 150mm). Ceramic wall thickness of 2.5mm ~ 9.5mm, the metal ring is 0.8mm ~ 1.6mm, in the case of strength permits, should be thinned wall of the ring.
2: Main features
- High mechanical strength
- High chemical stability
- Excellent heat endurance
- Competitive price from manufacturer
3: Main applications
- Used in chemical industry, Alkali industry,
- Protection of environmental, petroleum industry ,coal gas industry .
- Vailable for the distillation and absorption of a liquid and gas, atmospheric
- Vacuum distillation unit, crude distillation unit,
- Desulphurization system, gas liquid separator/separate of the gas and liquid etc.
