Carbon Raschig Ring for Acids and Alkalies Environment¹

Product Description Carbon Raschig Rings for Acids and Alkalies Corrosion ProcessesGraphite /Carbon Raschig Rings have assumed an important functional role in the working of absorption towers, distribution columns, scrubbers, etc, in chemical plants and refineries. With the growth of chemical industries, the need for versatile Raschig Rings has also grown proportionately.Graphite /Carbon Raschig Rings are characterised by unique properties as follows:Because of their high thermal conductivity they are resistant to severe thermal shocks.Low thermal expansion.They are resistant to practically all corrosive chemicals over a wide range of temperatures - these include almost all acids, alkalis, alcohols, organic solvents, inorganic compounds and salts.If required these can also withstand higher process temperatures. Impervious carbon rings are superior in oxidising conditions.Because of their excellent wettability by all liquids (water, inorganic salt solutions, organic solvents), they exhibit maximum efficiency during operation. This type of tower packing is selected mainly based on the chemical conditions involved as well as for reasons of mechanical strength, resistance to corrosion and a balance of cost, capacity and efficiency.Graphite /Carbon Raschig Rings exhibit such remarkable versatility that these find increasing usage in chemicals plants. There are few applications where the low cost of carbon rings does not play an important part in its selection.SpecificationSizeDimensionSurface AreaBulk WeightФ1919×19×3220600-650Ф2525×25×4194600-650Ф3838×38×6125600-650Ф5050×50×7120500-550Ф8080×80×976650-700Typical PropertiesAppearance Black Hollow RingSizemm40 mm / 25 mmCarbon Content%≥99Yield StrengthMPa≥6.0Compressive StrengthMPa≤3.0HardnessHB15Operating TemperatureoC-40 ~ 500Loss by Alkali Treatment%0.1~0.2 (60oC, 240h, 2% NaOH Solution)Suitable Medium All kinds of acid and alkali EnvironmentLife TimeYear≥2
