GCI Impregnated Carbon Brick

GLOBE CARBON INDUSTRIES, specializes in the manufacturing of Impregnated Carbon Bricks especially developed for high corrosion resistance against all acids & not suitable for alkalies, Excellent Resistance to thermal shocks, high crushing strength, Improved mechanical properties & it withstands temperature upto 180°C. Having low Porosity 2-3 % & average Carbon content 98% min and low Ash upto 2% max. It is mould manufactured product thus having very good dimensional accuracy +/- 1mm. and mainly used in all Phosphoric Acid Plants.

We offer superior specifications in our bricks which increases its life throughout, but since the method and place of application of the products are beyond its control, it's guarantee is therefore limited to the quality of materials delivered.
We can offer the Guarantee/warranty period of 4 years from the date of commissioning of any equipment against any mechanical damages & wear tear mortar due to chemical attack.
