FANRYN Rock Wool Pipe - High-Performance Thermal Insulation for Industrial Applications
FANRYN Rock Wool Pipe is a rigid, lightweight insulation product specifically designed for pipe systems in industrial, commercial, and energy facilities. It is manufactured from natural volcanic rock (basalt) and limestone, which are melted at over 1450°C and spun into fine, high-quality fibers. These fibers are then bonded with thermosetting resin and formed into pipe sections that provide excellent thermal and acoustic insulation.
