1050 degree high temperature calcium silicate tubes are used for heat insulation and fire resistant applications in high temperature pipes and equipment. Known for its high compressive strength, corrosion resistance and high-temperature structural integrity, calcium silicate is commonly used at high temperatures in industrial facilities, such as chemical plants, oil refineries and steam power plants. Because it is A rigid material with a relatively flat thermal conductivity curve, extremely high compressive strength, high bending strength, flame spread/smoke developed Class A rating, and non-flammable, it is widely used in high-temperature, industrial applications.
