High-density polyethylene (HDPE) piping systems have been used for municipal and industrial water supply for more than 50 years. Within PPI’s building and construction division, HDPE pipes used for ground source geothermal applications. Also known as ground energy systems or geoexchange systems. Submersible Column Pipe

Other applications of HDPE piping systems can find on the websites of other PPI divisions.

Introduction HDPE is currently manufactured from blends with a pipe material designation code of PE 3608 or PE 4710 and a color and UV stabilizer code of C or E according to ASTM D3350.

Common in geothermal

HDPE is available in IPS (Iron Pipe Size). And CTS (Copper Pipe Size). IPS sizes more common in geothermal ground loop applications. HDPE pipes and tubes are produced in coils and straight lengths. The exact pressure values ​​can found in the HDPE manufacturer’s documentation and in the lists.

High-density polyethylene

Definition High-density polyethylene (HDPE) is a plastic resin made by copolymerizing ethylene and a small amount of another hydrocarbon. The resulting base resin density for additives or pigments is greater than 0.941 g/cm.

Overview The piping material is critical to the overall success of the ground geothermal system. It must provide corrosion resistance, chemical resistance, flexibility, impact resistance, resistance to slow crack growth, long-term hydrostatic strength (pressure capacity), and temperature resistance. In addition, the ground loop heat exchanger material must provide suitable heat transfer capabilities.

Unique performance characteristics

HDPE is a strong, durable pipe material with unique performance characteristics that allow it to be used in a wide variety of applications using a variety of construction techniques. In the ground geothermal industry, HDPE one of the first pipe materials used due to the combination of properties that meet the specific needs of these applications as mentioned above.

HDPE piping systems

HDPE piping systems approved for geothermal ground loops in all model codes by the United States and Canada.

Low waste value

Advantages of HDPE Drinking water safety and long-term reliability Resistance to corrosion, tuberculation, deposits Flexibility for ease of installation Resistance to frost cracking Lightweight. Easy to carry Low waste value. Preventing theft in the workplace Strength. And durability to survive site installations No flame used to connect.

Piping systems

With many options to connect and connect Environmentally friendly recyclable material Heat fusible for virtually leak-free performance HDPE application Within PPI’s building. And construction division, HDPE piping systems use as ground loops for ground geothermal applications, also known as ground energy systems or geo exchange systems. Other applications of HDPE piping systems can  found on the websites of other PPI divisions.
