Recommendations for the Works with Refractory Glass Wool Products

First, weld pins to the surface of the equipment in advance and then tie the refractory glass wool over the surface of the equipment. If the temperature of the equipment is over 250℃, It is recommendable to adopt double–layer heat preservation method. Make sure that the seams of the outer and inner layers of glass wool are staggered to avoid heat loss due to the heat bridge formed. If temperature of the equipment exceeds 400℃, It is recommendable to use aluminum silicate for the inner layer and refractory glass wool for the outer layer, also staggering their seams. Finally wrap the outer cover layer which serves both as protection to he glass wool and decoration.
