Customized Ceramic Fiber Special-Shaped Parts

Product Overview

Ceramic fiber special-shaped parts are custom-made refractory insulation products manufactured from high-purity ceramic fiber wool through processes such as wet-process vacuum suction molding and compression molding. They break through the shape limitations of traditional flat materials and can be precisely processed into various complex, high-precision, and structurally stable insulation components tailored to the intricate structures and specific operating conditions of equipment.

In the international market, these refractory special-shaped parts are widely used as alternatives to expensive and crack-prone monolithic refractory bricks. Especially in areas with irregular corners, curved pipes, nozzles, sight glass openings, furnace doors, and other complex geometries within equipment, custom ceramic fiber special-shaped parts enable seamless fitting and precise installation, significantly reducing heat loss.

Core Advantages and Performance Features

✔ Exceptional High-Temperature Resistance

Continuous operating temperature ranges from 1000°C to 1430°C (depending on the material).

Maintains structural integrity under short-term high-temperature thermal shocks, offering excellent thermal stability.

✔ Lightweight and High Strength

Bulk density is only 1/5 that of traditional refractory bricks, significantly reducing equipment weight.

Compressive strength can reach 0.5–1.0 MPa, retaining structural strength even at high temperatures.

✔ Low Thermal Conductivity and High Insulation Efficiency

Thermal conductivity is as low as 0.08–0.18 W/m·K, effectively blocking heat transfer.

Energy-saving performance is over 20% higher compared to traditional materials at the same thickness.

✔ Chemical Corrosion Resistance and Thermal Shock Resistance

Offers good resistance to most acids, alkalis, and splashes of molten metals.

Withstands rapid thermal cycling without cracking or spalling.

✔ Environmentally Friendly and Harmless

Contains no asbestos or other harmful components; no toxic fumes are released during production or use.

Complies with environmental standards such as EU RoHS and REACH.
