HDPE U-Bend Coils save installers precious field time fabricating u-bends which often require larger boreholes. HDPE U-bend coils contain a very tight 180 degree radius u-bend which is factory installed. The two pieces of pipe are fused to the u-bend and the pipe is neatly packaged into a configuration which can be easily uncoiled in the field. This ends the need for field fabrication of u-bends coils. The u-bends have a unique on piece molded design which contains a space for a vent hole. An anti-buoyancy wing tube can be fitted easily into the vent hole, which minimizes the possibility of a loop assembly "floating" out of the borehole. The vent port may also be used to connect weights, stiffeners, or other devices without risking damage or compromising performance.
Single HDPE Coils-we offer standard polyethylene pipe coils in 500' lengths in 3/4", 1", 1 1/4", and 2" in SDR 11 and SDR 9. Other coil lengths are available by special order.

HDPE Geothermal Piping System-Key Benefits
- Cost Efficient Installation- Easy to join, lightweight, and flexible to help reduce construction and installation costs.
- Tough and Durable- Excellent impact and abrasion resistance. Pressure ratings based on long term testing. Exceptional resistance to slow crack growth and environmental stress cracking.
- Ductile and Flexible- with a bending radius equal to approximately 20 times the diameter of the pipe, HDPE piping has the flexibility, that will make trench and downhole installation easy.
- Resistant to Chemicals and Corrosion- Excellent resistance to most chemical compounds and aggressive soils.
- Thermally Conductive- HDPE pipe offers high strength resin pipe material to minimize pipe wall thickness and maximize heat transfer.
- Leak-Tight Joining- Long continuous coils or straight lengths reduce joining requirements. Properly made heat fusion joints are as strong as the pipe itself and do not break.
- Superior Flow Characteristics- HDPE pipe offers high volume flows with low flow resistance. The hydraulically smooth, non-wetting surface provides excellent flow properties. A Hazen-Williams C-Factor of 150-155 is typically used to estimate flow resistance. HDPE pipe does not rust, rot, corrode, tuberculate, or support biological growth.
- Sequential Footage Markings- Coils contain footage marker indications every 2' to assist with proper depth setting in borehole installations.
