Material: rock wool
Facing: single-sided aluminium foil
Length: 1m
Density: 70 kg/m³- 180 kg/m³
Inner Diameter: 22mm- 1220mm
Thickness: 25 mm- 150 mm
Highest Working Temperature: 400℃
Rock Wool Pipe Sections are made from non-combustible, inorganic rock fibers and are suitable for the insulation of small and large diameter heating and ventilation pipes.
High-efficiency thermal insulation: low thermal conductivity (≤0.040 W/m·K), effectively blocking heat transfer, reducing energy loss, and significantly reducing operating costs.
Class A fire retardant: high temperature resistance of more than 700℃, non-combustible in case of fire, no toxic smoke, in line with building fire safety standards, ensuring the safety of equipment and personnel.
Hydrophobic and moisture-proof: adding a hydrophobic agent, fiber hydrophobicity ≥98%, long-term exposure to a humid environment can still maintain stability, avoiding the decline of thermal insulation performance.
Environmentally friendly and durable: no asbestos, no CFC/HCFC, in line with environmental protection requirements; anti-corrosion, anti-aging, service life of more than 20 years.
Lightweight and easy to install: the pipe diameter and thickness can be customized according to the pipe size, the slit design is matched with aluminum foil veneer, which is convenient to install and greatly shortens the project cycle.
