Light Weight Fire Clay Insulation Brick – B1/B2 Series for Boiler Furnace Lining
Our B1/B2 series Light Weight Fire Clay Insulation Brick is a premium refractory material engineered for superior thermal management in high-temperature industrial environments, particularly in boiler insulation and furnace lining. Manufactured from super-pure raw materials with strictly classified fillings, our bricks significantly reduce structural load and heat storage while maintaining excellent thermal shock resistance and long service life.
With a standard size of 230*114*65mm, low bulk density (0.60-1.25 g/cm³), and working temperatures from 900°C to 1600°C, our lightweight insulation bricks provide a cost-effective solution to reduce fuel consumption, construction costs, and furnace downtime.

Frequently Asked Questions (FAQ)
Q1: How do I select the right grade for my furnace?
Selection depends on maximum operating temperature, bulk density requirements, and thermal cycling frequency. For example, B-1 to B-5 are suitable for 900-1300°C applications, while B-6 to C-3 handle up to 1500°C. Please provide your design specifications for a tailored recommendation.
Q2: Can you provide custom shapes and sizes?
Yes, we offer customizable shapes (standard, special-shaped, and arch bricks) based on your CAD drawings to ensure a perfect fit for your equipment.
Q3: What is the typical delivery period?
Standard delivery is 10-15 days. MOQ is 500 pieces, and our supply capacity is 1,000 tons/month.
