B1 B2 Lightweight Fire Clay Insulation Brick 230x114x65mm For Boiler Furnace Lining
Our B1/B2 grade Light Weight Fire Clay Insulation Brick is a premium refractory material specifically engineered for superior thermal management in high-temperature industrial applications, especially in boiler insulation and furnace lining. With a standard size of 230x114x65mm and a low bulk density (0.60~1.25g/cm³), it significantly reduces structural load and heat storage. This brick offers excellent thermal insulation, good thermal shock resistance, and can withstand working temperatures from 900°C to 1600°C, making it a cost-effective choice for reducing fuel consumption and operational costs.
