FANRYN Precision-Engineered Rock Wool Pipes Set New Standard for Industrial Thermal Management

[Beijing, 2025.09.17] – FANRYN is defining the future of industrial insulation with its high-precision rock wool pipes, manufactured to exceed rigorous international standards including GB/T 19686 and GB/T 8624. Our products guarantee exceptional performance for the most demanding applications in energy, petrochemical, and heavy industries.

A key differentiator is our commitment to precision manufacturing. We maintain a strict eccentricity tolerance of ≤5mm and a shot content of ≤12%, ensuring uniform insulation thickness, superior structural integrity, and minimal dusting during handling and installation. This results in a more efficient, durable, and safer installation, reducing long-term maintenance costs.

Crafted from basalt and limestone melted at over 1450°C, our pipes offer a thermal conductivity of ≤0.044 W/mK, ensuring maximum energy conservation. Furthermore, their inherent Class A1 non-combustibility provides critical passive fire protection, safeguarding assets and personnel.
