Product Information
FANRYN Rock wool pipe is manufactured from natural basaltic rock and limestone. These raw materials are melted at temperatures exceeding 1450 ℃ in a cupola furnace. The resulting molten lava is transformed into fine fibres through a high-speed spinning process. These inorganic fibres are then bound together with a thermosetting resin to form a stable and durable material. Finally, the product is precision-cut into standardized dimensions to facilitate easy handling and installation.

Main application of the bare rock wool pipe:
-Power Plants: Used in boiler systems, steam lines, and exhaust ducts.
-Oil Depots & Refineries: Insulates fuel pipelines, storage tanks, and process piping.
-Petrochemical Plants: Protects pipelines carrying chemicals, gases, and high-temperature fluids.
-Shipbuilding & HVAC: Provides insulation and fire safety in marine engine rooms and commercial building services.
Advantage of the rock wool pipe:
1.Thermal Insulation
Effectively reduces heat transfer in pipelines, maintaining consistent temperatures in both high and low-temperature systems, thereby improving energy efficiency and operational stability.
2.Fire Safety
Class A1 fire-rated material offers reliable passive fire protection. It does not contribute to fire spread, smoke, or toxic fumes, enhancing safety in high-risk environments.
3.Acoustic Control
The dense fibrous structure absorbs sound and dampens vibration, reducing noise from fluid transport, mechanical operations, and industrial processes.
4.Corrosion Resistance
Minimizes risk of Corrosion Under Insulation (CUI) by limiting condensation on metal surfaces through stable thermal performance, extending service life of pipelines.
5.Environmental Sustainability
Manufactured from abundant natural minerals like basalt and recycled content. Free of CFCs, HCFCs, and other ozone-depleting substances, supporting green building initiatives.
6.Moisture Resistance
Hydrophobic properties prevent water absorption, ensuring long-term insulation performance and material integrity even in humid or outdoor conditions.
7.Energy Conservation & Emissions Reduction
Sign lowers heat loss in heating/cooling systems, directly reducing fuel consumption and CO2 emissions. Supports compliance with energy efficiency standards and sustainability goals.
