Engineered from Molten Rock: The Science Behind FANRYN Rock Wool Pipe

FANRYN Rock Wool Pipe begins its life as natural basalt and limestone, materials chosen for their inherent stability and durability. Through a high-precision manufacturing process, these rocks are superheated in a cupola furnace at temperatures exceeding 1450°C, transforming them into molten lava. This lava is then expertly fiberized, creating a web of fine, inorganic filaments.

The true engineering lies in bonding these resilient fibers with a thermosetting resin, forming a rigid, pipe-section structure that traps countless tiny air pockets. This intricate matrix is the key to performance: the still air within these pockets provides exceptional thermal resistance, while the dense, interlocked stone fibers deliver outstanding acoustic damping and structural integrity. The result is not just an insulation material, but a high-performance system engineered to manage energy, sound, and fire in demanding industrial environments.

• High-Temp Origin: Born from fire (≥1450°C) to withstand extreme conditions.

• Fibrous Matrix: Millions of tiny air pockets locked within stone fibers provide superior, lasting thermal performance.

• Rigid Structure: The thermosetting resin creates a self-supporting pipe section that maintains its shape and thickness over time, ensuring consistent insulation value.

Insulation and fireproof of huge projects like power plant, oil depot and petrochemical works.
