Introduction
HDPE is currently produced from compounds with pipe material designation codes of PE 3608 or PE 4710, and a color and ultraviolet stabilizer code of C or E, per ASTM D3350.
HDPE pipe is a plastic pipe made of high-density polyethylene (HDPE) with excellent chemical resistance, corrosion resistance and impact resistance. It is lightweight, flexible and easy to install, and is commonly used to transport drinking water, natural gas, wastewater and industrial chemicals. HDPE pipe is also widely favored for its durability and leak-proof performance, suitable for long-distance transportation and underground pipeline systems. It can remain stable under high pressure conditions and has low maintenance costs.
Definition
High density polyethylene (HDPE) is a plastic resin made by the copolymerization of ethylene and a small amount of another hydrocarbon. The resulting base resin density, before additives or pigments, is greater than 0.941 g/cm.

HDPE Applications
Within PPI's Building & Construction Division, HDPE piping systems are used as the ground loops for ground source geothermal applications, also known as earth energy or geoexchange systems.
For other applications of HDPE piping systems, please refer to the webpages of PPI's other divisions.
