Discover the efficiency of pre-Insulated pipes for buried applications

Looking for a reliable solution to maintain temperatures over longer distances? Pre-insulated pipes for geothermal applications from POLYMELT. Pre-insulated PP-R and PP-RCT plastic pipes. Designed for underground installation, these pre-insulated pipes offer numerous advantages for various applications, ensuring energy efficiency and cost-effectiveness.

Benefits of working with pre-Insulated pipes:

  1. Energy savings: Our pre-insulated pipes for geothermal applications are insulated with rigid PUR foam and enclosed in a protective jacket pipe, minimizing energy losses during transportation. Whether it’s hot water, drinking water, heating, or cooling water, these pipes ensure efficient temperature maintenance over extended distances, making them real energy savers.
  2. Low thermal conductivity: With a very low thermal conductivity ranging from approximately 0.024 to 0.035 W/mK, our pre-insulated pipes effectively reduce heat transfer, resulting in minimal temperature variations along the pipeline.
  3. Corrosion resistance: Thanks to their construction, our pre-insulated plastic pipes are resistant to deposits and corrosion, eliminating the need for corrosion additives and reducing maintenance costs over time.
  4. Easy installation: Lightweight and easy to connect, our pre-insulated pipes minimize installation time and labor costs. Their suitability for both new construction and retrofits makes them a versatile choice for various projects.
  5. Versatile applications: Our pre-insulated pipes are suitable for a wide range of applications, including potable hot and cold water, district heating and cooling, and thermal water systems. Whether it’s for residential, commercial, or industrial use, these pipes offer reliable performance and energy efficiency.

POLYMELT pre-insulated PP-R & PP-RCT platic pipes: ideal for various applications:
