World-Class Piping Solutions for Sustainable District Energy Systems

District heating and cooling systems are a game-changer for commercial and industrial sites, delivering reliable solutions for both heating and cooling with efficiency and ease.

These systems use steam, hot water, or chilled water to transfer energy from its source to consumers. Pre-insulated piping systems play a vital role in ensuring effective energy delivery, making sure heating and cooling are precisely where they’re needed, with minimal waste.

PERMA-PIPE’s energy-efficient piping solutions take this a step further. Engineered for optimal distribution of both heating and cooling energy, our systems reduce maintenance costs, enhance efficiency, minimize heat loss, and offer lasting durability—all while maintaining environmental safety. When it comes to managing both heating and cooling needs, trust a solution proven to deliver results.

Applications

  • In order to heat and cool commercial and industrial establishments, district heating and cooling systems are quite effective. The most frequent method utilized in these systems to move energy from its source to consumers is chilled or hot water, and pre-insulated piping systems are essential for effectively delivering energy to where it is required.

    Energy for heating and cooling may be distributed effectively and efficiently using PERMA-PIPE's pre-insulated piping systems.

  • The sole purpose of steam energy distribution systems is to supply energy for facility heating needs. They work well in systems with dispersed building sites or in situations where a building's height would cause an excessive amount of pressure in a water system, where energy must travel long distances. High-quality pre-insulated piping systems are crucial for achieving efficient energy transfer by minimizing heat loss in the distribution system.

    Pre-insulated pipe systems from PERMA-PIPE meets all project specifications for transmitting steam energy through subterranean piping systems.

    CORROSION UNDER INSULATION
    A severe type of exterior, localized corrosion that frequently affects insulated steel piping systems is called "corrosion under insulation" (CUI). Moisture, operating temperature and chemical exposure are the most frequent causes of CUI (water, in all its forms, is the biggest cause of corrosion). Through correct system configuration, material specification, installation, and maintenance, these CUI contributors can be managed to prevent it from happening.

    With regard to CUI contributions, PERMA-PIPE offers cutting-edge solutions. Our products can be coated to prevent the piping system from prematurely failing due to corrosion, which would otherwise cause production to stop, cost money in maintenance and repairs, and pose a risk to health and safety.

    GALVA-GARD - Smoothwall, spiral welded, 10-gauge steel conduit, hot dipped galvanized with urethan outer coating. Service pipe(s) and insulation can be selected from any material suitable for the application. Single or multiple steel service pipes insulated with mineral wool or calcium silicate.

    ANTI-CORROSION COATINGS:
    Anti-corrosion coatings function as a protective layer that prevents or delays the development of corrosion on the metal surface beneath the carbon steel pipe. It ensures that priceless natural resources and other items arrive at their destination safely and effectively by avoiding external corrosion with the application of either single or multi-layer anti-corrosion coatings.

    To protect pipeline and piping systems from external corrosion, our anti-corrosion coatings are available in one, two, or three layers. These coatings offer a range of capabilities and complexity, catering to various performance and budget requirements while extending the lifespan of the piping system.

    Our Three-Layer System includes Fusion Bonded Epoxy (FBE) Primer, Polymeric Adhesive intermediate layer, and High-Density Polyethylene (HDPE) outer jacket.

    Fusion Bonded Epoxy (FBE) Coating is a cutting-edge solution crafted to deliver unparalleled protection for pipelines in even the most demanding environments. This single-layer coating provides exceptional defense against chemical exposure, soil stress, and environmental wear. Additional features include:
    Abrasion and Moisture Resistance to withstand harsh environments.

    High-Temperature Capabilities, supporting operations up to 302°F (150°C). FBE provides the versatility and reliability to meet your needs, ensuring your pipelines remain secure and protected for years to come.

    Rubberized Asphalt (RA) is a bonded external pipe coating system, expertly formulated for superior protection and long-term durability. This system featured a base layer of rubberized asphalt adhesive, offering exceptional resistance to corrosion, moisture, and soil stress.
