FEATURE OF IMPERVIOUS GRAPHITE

Impervious graphite is a traditional material selected for its high conductivity, good resistance to most chemical except oxidising acids and good mechanical properties, specially treated with synthetic resins to ensure that the base structure is fully impervious to liquids under pressure. The excellent performance and properties of graphite make it very useful as an engineering material for a wide range of heat transfer and chemical process equipment. Graphite forms no compounds due to corrosion, no protective surface films as do many metals, which depend on their protective oxide films for their corrosion resistant. Its surfaces therefore remain smooth and thus more resistant to scale build-up resulting in much lower fouling factors being required.

Graphite equipments have been employed in the field of chlor-alkali, chemical, petrochemical, pharmaceutical, agrochemical, steel pickling and environmental protection industry including heat exchanger, hydrochloric acid synthesis unit, dilution system, absorbers, evaporator, gas scrubber, quench, column etc. The customer has gotten the following excellent feature and benefits ::-

- Excellent Corrosion Resistant
- Outstanding Heat Transfer Properties
- Non-Contaminating
- Reasonable Price compared to other material with similar quality
- Simple Joining
- Light weight
