Clay bricks with low porosity have obvious advantages in heat exchange equipment, mainly in the following aspects:

I. High strength and high compactness

The porosity of clay bricks with low porosity is usually lower than 17% or even lower. This low porosity structure makes the brick more compact and its compressive strength is significantly higher than that of ordinary clay bricks. In heat exchange equipment, this high-strength characteristic can effectively withstand the pressure of high-temperature gas and liquid, and reduce the damage caused by mechanical stress.

II. Excellent erosion resistance

Low porosity clay brick has strong tolerance to acidic or neutral chemicals. Its low porosity structure can effectively prevent the penetration of corrosive gases and liquids, thus prolonging the service life of the equipment. In the heat exchange equipment of chemical industry, this anti-erosion ability is particularly important, because it can resist the erosion of many chemicals.

III. Low thermal conductivity and energy-saving effect

Because of the low porosity, the thermal conductivity of low porosity clay brick is also low. This means that in the heat exchange process, the heat loss is less and the energy utilization efficiency is higher. In heat exchange equipment, this low thermal conductivity can effectively reduce the heat loss and improve the thermal efficiency of the equipment.

IV. Good thermal shock stability

Low porosity clay brick has good thermal shock stability. Even in the case of rapid temperature change, the brick body will not crack or peel off easily. This characteristic enables the clay brick with low porosity to withstand frequent temperature changes in heat exchange equipment and prolong the service life of the equipment.

V. Long life and low maintenance cost

Because of the high strength, corrosion resistance and thermal shock stability of low porosity clay bricks, their service life is significantly longer than that of ordinary refractories. This means that the use of low porosity clay bricks in heat exchange equipment can reduce the replacement frequency and maintenance cost.

VI. Good thermal conductivity

Low porosity clay brick also has good thermal conductivity, which is very important for the efficient operation of heat exchange equipment. It can ensure the effective transfer of heat inside the equipment, thus improving the heat exchange efficiency.

To sum up, low porosity clay brick has excellent performance in heat exchange equipment because of its high strength, low thermal conductivity, excellent corrosion resistance and good thermal shock stability, which can significantly improve the operating efficiency and service life of the equipment.
