Calcium Silicate Block

Calcium Silicate Block

Slab, Lags, Bricks, Pipes & Powder up to 1000 C

Insulation brick based on Calcium Silicate is reacted Calcium Silicate containing reinforcing fibers (non-asbestos). It offers thermal efficiency of flexible insulation like mineral wool and strength of conventional Insulation Bricks.

Insulation pipes are ideal replacement for fibrous insulation and are un-matched in places where insulation is exposed to water, floor traffic, and impact loads etc.

Insulations based on Calcium Silicate meet specifications as under: –
• IS 8154 & 8428
• Relevant Naval Specifications
• ASTM C 533-90
• B.S.3958 part II.

Advantages: –
• Low Thermal Conductivity
• Rigid & Light Weight (Density 250 kg/M3)
• Good Mechanical Strength (Above 10kg./cm2)
• Fire Resistant
• Low shrinkage
• Low specific Heat
• Non Combustible & Non Corrosive
• Low Maintenance Cost
• Re-usable & Long life
• Easily Workable (cuts easily)

Applications: –
• Cement: Preheaters/Precalciners, Coolers, TAD etc.
• Aluminium: Reduction pots, Other Thermal Process Equipment
• Glass: Furnace, Recuperators, Annealing etc.
• Steel: Various types of furnaces as refractory back up.
• Power Plants: Boilers, Steam Lines, Recuperators etc.
• Fertilizers, Petrochemicals & Refineries: Reformers, Steam Lines, Furnaces, Incinerators, High Temp. Equipments, Hot Gas & Chemical lines etc.
• Ceramic: Tunnel kilns.
• Ship Building: Boilers, Turbines, Steam Lines, Fuel Gas ducts etc.
• Chemicals: Boilers, High Temp. Reactors, Fuel Gas ducts, Steam/Thermic fluid lines, Dryers, Furnaces etc.
• Others: Significant fuel saving can be obtained in Sugar Mills, Foundries Rolling Mills and other industries, which use thermal equipments at High Temperature.
