Charter Plastic manufactures high density polyethylene (HDPE) pipe for geothermal applications. The PE 4710 IPS geothermal pipe is designed for geothermal heat exchangers. The pipe is not designed for use in hot water applications and for in house use. After installation, the pipes are tested hydrostatically and pneumatic testing should not be done with these pipes. The pipes are available in coils, reels, and straight lengths. No lubricant should be used on the pipe and the pipe should not be exposed to direct flame.
Charter Plastics IPS pipe is based on outside diameter. Heat fusion is the preferred method for joining this pipe. All personnel conducting fusions should be experienced and follow guidelines published by the pipe manufacturer or by PPI in TR 33. It may also be joined with OD Mechanical fittings designed for pipe made to D 3035 Standards. A stiffener should be inserted when using OD Compression type fittings on pipe < 2”. Never use any lubricant on the pipe. Do not expose the pipe to direct flame.
The charter geo loop is used in both horizontal and vertical well applications. Charter Geo Loops come as a single coil. Each loop is comprised of a supply and return pipe made to your specified length, run parallel, with a Charter U-Bend (180° fitting) factory fused to one end. The other end of the pipe is sealed and the entire coil is pressurized with air. Charter Geo Loops are available in 3/4”, 1” and 1-1/4” IPS pipe sizes.
