Piping geo-fluids
In many cases the source of geothermal fluid to be used for a direct use application is located some distance away from the user. This requires a transmission pipeline to transport the geothermal fluid. Even in the absence of transmission line requirements it is frequently advisable to employ other than standard piping materials. Geothermal energy for direct use applications is usually transported in the liquid phase and has some of the same design considerations as water distribution systems. Several factors including pipe material, dissolved chemical components, size, installation method, head loss and pumping requirements, temperature, insulation, pipe expansion, and service taps should be considered prior to final system selection. The characteristics of carbon steel, fiberglass, polybutylene, asbestos cement, polyvinyl chloride and chlorinated polyvinyl chloride, polyethylene, and copper as piping materials are discussed, as are installation and pipeline insulation.
