Rigid pipeline insulation consists of foam boards or rigid foam panels installed around pipelines to minimize heat transfer and prevent energy loss or gain. This insulation type is commonly used in industrial, commercial, and residential applications to maintain desired temperatures in heating, ventilation, and air conditioning (HVAC) systems, as well as in process pipelines. Its rigid structure offers durability and structural support, making it suitable for both indoor and outdoor installations where mechanical protection is required. Rigid pipeline insulation helps improve energy efficiency, reduce operating costs, and enhance overall system performance.
