Raschig carbon rings 19 mm

Raschig carbon rings 19 mm Keywords: raschig carbon ring, graphite ring, carbon hollow ring The carbon (graphite) Raschig ring is highly resistant to the influence of high frequencies, strong acid or strong alkali, where packings made of other materials, such as ceramics, plastic and metal, can easily easily corrode. The carbon (graphite) Raschig ring is characterized by high resistance in the environment of HF, strong acid or strong alkali, where packings made of other materials, such as ceramics, plastic and metal, can easily be corroded. Advantages: The Raschig carbon ring has a low coefficient of thermal expansion, high resistance to high-frequency radiation, strong acids and strong alkaline environments, as well as high weight and high mechanical strength.
