GeoGuard™ Geothermal

Features & Benefits

•     Manufactured from PE 3608, high density polyethylene (HDPE)
•     Superior strength and durability with a lifetime warranty.
•     Available in: Sizes ranging from 3/4" through 2"
•     Copper Tubing Size (CTS) or Iron Pipe Size (IPS)
•     Standard Dimension Ratios (SDR 11)
•     Meets or exceeds the requirements of IGSHPA, sized in accordance with AWWA C901.
•     Coiled lengths with factory installed U-bends provide for seamless installations.

GeoGuard™ tubing is extruded using high density polyethylene (HDPE) in parallel coils with u-bends factory installed and tested. Available in standard and custom lengths to meet your application needs. HDPE has excellent chemical resistance, is light weight yet tough, making it ideally suited for geothermal installations in wells, ponds or trenched. Black in color to optimize heat transfer.

Installation:

Suitable for direct burial by plowing, directional drilling or placed in a trench. Pipe shall be supported through the use of proper embedment and compaction in open cut installations. For more information regarding installation requirements obtain a copy of the “Polyethylene Handbook” from the Plastic Pipe Institute.

Joining:

Both the CTS and IPS tubing sizes using any of the heat fusion techniques or approved mechanical fittings that are fully pressure rated and designed for assembling HDPE service tubing.
