Product Description
Our rock wool pipe sections are pre-formed tubular insulation made from premium basalt rock wool with low slag ball content and long flexible fibers. Classified A1 non-combustible, they withstand high temperature up to 650°C, delivering stable thermal insulation to cut pipeline heat loss and energy costs. Optional hydrophobic treatment effectively resists moisture absorption, while the porous fiber structure provides excellent sound absorption to eliminate pipeline operating noise. lightweight and easy to cut, drill and tailor for all pipe sizes. Aluminum foil facing is available as vapor barrier for outdoor & damp environments. Widely applied for steam, heating, HVAC, chemical and power pipeline insulation in industrial plants, commercial buildings and thermal power stations.
Core Advantages of Rock Wool Pipe Insulation
High-Efficiency Pipeline Thermal Insulation
The interlaced long flexible basalt fiber structure locks massive static air, delivering ultra-low thermal conductivity of 0.035–0.040 W/m·K. It drastically cuts heat loss of hot steam, heating and industrial pipelines, stabilizes medium temperature, lowers boiler energy consumption and achieves long-term energy saving for thermal systems.
Non-Combustible A1 Grade Fire Safety
Made of inorganic basalt rock wool with melting point over 1000°C, it fully complies with Euroclass A1 non-combustible standard EN 13501-1. It won’t burn, drip or emit toxic fumes under extreme heat, blocking flame spread along pipelines, ideal for power plants, chemical factories and high-rise HVAC piping.
Professional Sound Absorption & Noise Reduction
Dense porous fiber structure absorbs pipeline vibration and fluid flow noise efficiently. It eliminates pipeline resonance noise in equipment rooms, workshops and central air conditioning systems, meeting industrial and commercial building noise control requirements.
Optional Hydrophobic & Anti-Moisture Property
With hydrophobic treatment, the pipe sections achieve over 98% water repellency, resisting dew and moisture penetration. It avoids thermal performance attenuation in humid workshops, outdoor buried pipelines and underground piping projects.
Easy Installation & Stable Structure
Low slag ball, complete long fibers ensure stable molding without powder shedding. Pre-split tubular design is lightweight, easy to cut and wrap on pipes. Customizable inner diameter, thickness and aluminum foil facing are available for all standard pipeline sizes.

Industry Applications
High-Temperature Steam & Heating Pipeline Insulation
Wrapped around hot steam, central heating and hot water pipelines, it effectively locks heat inside pipes, greatly reduces medium heat loss, stabilizes pipeline operating temperature, and cuts boiler energy consumption for factories, residential districts and commercial complexes.
Chemical & Petrochemical Industrial Pipelines
Suitable for high-temperature process pipelines in chemical plants, refineries and pharmaceutical workshops. A1 non-combustible performance prevents fire spread along pipelines, while high temperature resistance ensures stable insulation under long-term hot medium circulation.
HVAC Central Air Conditioning Pipe Insulation
Used for large air supply & return pipes in malls, hotels, office buildings and hospitals. It insulates against cold/heat loss and absorbs pipeline airflow vibration noise, balancing indoor temperature and lowering equipment operation noise.
Power Plant & Thermal Station Equipment Piping
Applied on boiler auxiliary pipes, flue pipelines and circulating water pipelines of thermal power stations. It withstands sustained high working temperature, blocks heat radiation to workshop space, and improves on-site working safety.
Mechanical Equipment Noise Reduction & Thermal Isolation
Insulate circulating pipelines of water pumps, air compressors and industrial machinery. Dense fiber structure absorbs pipeline resonance and fluid flow noise, lowers surface temperature of equipment pipes to avoid scald risks.
Outdoor & Buried Pipeline Thermal Protection
Hydrophobic rock wool pipe with aluminum foil facing can be used for outdoor overhead pipelines and shallow buried piping. The water-repellent property avoids insulation performance degradation caused by rain, dew and underground moisture, extending pipeline service life.
