K26 Insulation Brick
K26 insulation brick is a special type of brick that is slightly denser than K23 brick. Moreover, it can withstand high temperatures and act as thermal insulation. Customers can use it as a lining inside casting furnaces, forging furnaces and ceramic kilns.
- Al2O3(≥): 51%
- Bulk Density: 0.78g/cm3 – 0.80g/cm3
- Cold Crushing Strength: 1.3MPa
- Thermal Conductivity: 0.27W/(m·K) – 0.33 W/(m·K)
Brief Introduction of K26 Insulation Brick
Just like the K23 insulating refractory bricks, these are perfect for insulating heat. Moreover, the low thermal conductivity of K26 insulation brick effectively reduces heat transfer and improves energy efficiency. Besides, Kerui can cut smaller bricks or add channels for heating elements according to the specific requirements of the customer. In other words, Kerui can meet any needs of customers.

K26 Insulation Brick Usages
Industrial Kiln
As a type of mullite insulation brick for sale, we commonly use K26 insulation bricks as thermal insulation layers in industrial kilns. It can effectively reduce heat loss and improve the energy efficiency of the kiln. So, we can see it in various high-temperature kilns. Such as steel smelting furnaces, glass kilns and ceramic kilns.
Heat Treatment Furnace
We can also use K26 fire bricks in various heat treatment furnaces. Such as quenching furnaces, tempering furnaces and annealing furnaces. It can effectively isolate the high-temperature furnace from the external environment. So, they provide a stable heat treatment environment and reduce energy consumption.
High Temperature Equipment
You can also see K26 insulation bricks in the insulation layers of various high-temperature equipment. Such as furnace walls, heating furnaces, furnaces, etc. It can lower the surface temperature of the equipment and reduce heat conduction. What’s more, it improves the efficiency and safety of the equipment.
High Temp Pipes and Chimneys
K26 insulating fire brick, like insulating fire bricks K23, can be used as the insulation layer for high-temperature pipes and chimneys. They prevent heat loss and overheating of pipes or chimneys. In addition, they also effectively reduce energy waste and improve the safety of pipes and chimneys.
Thermal Energy Storage System
Kerui K26 insulation bricks can meet the usage conditions of thermal energy storage systems. Such as thermal energy storage tanks and thermal energy storage furnaces. Therefore, its excellent thermal insulation properties help reduce heat loss and achieve efficient storage and utilization of thermal energy.
Other Industrial Equipment
Customers can also use them for thermal insulation of thermal power plants, nuclear power plants, production catalysts, heat exchangers, reactors, rocket engines, jet engines and other key components. At the same time, Kerui insulation bricks can also ensure the normal operation and safety of the equipment.
