A-Class Rock Wool Sheets Suitable For Industrial Equipment Heat Retention

Rock wool boards are widely used in the thermal insulation of industrial equipment due to their excellent high-temperature resistance, thermal insulation performance, fire resistance, and chemical stability. Their core value lies in reducing heat loss from equipment, maintaining stable process temperatures, ensuring production safety, and meeting the rigorous requirements of different industrial scenarios.

Introduction

High-temperature heating/heat exchange equipment usually operates at temperatures ranging from 300°C to 800°C. Rock wool boards are required to provide long-term and stable high-temperature insulation to prevent heat loss from increasing energy consumption or causing process fluctuations. This category includes heating equipment such as the furnace walls and tops of industrial boilers (steam boilers, hot water boilers), the outer insulation of the lining of resistance furnaces, induction furnaces, and hot blast stoves, and the insulation of the cylinder and pipelines of heat-conducting oil furnaces. It also encompasses heat exchange equipment like the shell insulation of heat exchangers (shell-and-tube, plate-type) and the outer insulation of heat exchange surfaces in waste heat recovery devices (e.g., sintering machine waste heat boilers, power plant condensers) to reduce waste heat loss during transmission.

More Applications

Pipeline systems are one of the core application scenarios for rock wool boards, especially suitable for pipelines transporting high-temperature fluids (steam, heat-conducting oil, high-temperature process gas) or low-temperature pipelines requiring anti-condensation measures. For high-temperature pipelines, this includes the full-section insulation of power plant steam pipelines (main steam pipelines, reheat steam pipelines), heat-conducting oil transmission pipelines in chemical parks, and hot blast pipelines in iron and steel plants, which need to be paired with waterproof outer layers (such as aluminum foil, iron sheets) to cope with outdoor or humid environments. For low-temperature pipelines, rock wool boards can assist in reducing the infiltration of external heat into low-temperature medium pipelines of some industrial refrigeration equipment (e.g., refrigerant pipelines at -20°C to 5°C) and prevent pipeline condensation (requiring moisture-proof layers to avoid the impact of moisture absorption by rock wool on insulation performance).

Industrial Applications

In humid or outdoor scenarios (e.g., outdoor pipelines, underground storage tanks), moisture-proof layers (such as polyethylene films, aluminum foil composite films) should be wrapped around the outer side of rock wool boards, and waterproof protective layers (such as iron sheets, glass fiber reinforced plastic sheets) should be added to prevent rock wool from failing due to moisture absorption. The thickness of rock wool boards should be matched according to the equipment temperature and insulation requirements (e.g., a 1 MPa steam pipeline requires a thickness of 50-80 mm, and an 800°C high-temperature furnace requires a thickness of 100-150 mm) to avoid insufficient thickness leading to poor insulation performance or excessive thickness increasing costs. During construction, rock wool strips should be used to fill the gaps at the joints to avoid the "thermal bridge effect". Especially for special-shaped parts such as pipeline elbows and valves, customized special-shaped rock wool components are required to ensure sealing.
