Rock wool pipes are applied in diverse fields as follows:

Building construction: In buildings, they're used for HVAC system insulation and fire protection. Installed on ducts and pipes, they cut heat loss and boost energy efficiency. Their fire resistance enhances building safety. Also, they insulate exterior walls and roofs, maintaining indoor comfort and reducing heating/cooling energy use.

Industrial pipelines: Widely used in industries like petroleum, chemical, and power for pipeline insulation. For steam, hot oil, and gas pipelines, they prevent heat loss, ensure normal medium flow, and cut energy consumption. In chemical plants, their corrosion resistance makes them suitable for corrosive media pipelines.

Refrigeration and cold-chain: They're crucial in these systems, insulating cold storage, trucks, and equipment. By blocking external heat, they keep a low temperature, improve refrigeration efficiency, and safeguard cold-chain goods.

Shipbuilding and marine: Used for onboard pipeline and equipment insulation and soundproofing in ships. Applied to air-con, seawater cooling, and fuel pipelines, they stop heat loss, reduce noise/vibration, and improve the onboard environment. Their water and corrosion resistance fit the harsh marine setting.

Automotive: In cars, they're in thermal management systems, like the engine compartment and air-con. They insulate engine components, reducing heat transfer and improving engine and air-con efficiency. Also, they lower noise for a more comfortable ride.
