Blue Diamond has manufactured HDPE (High Density Polyethylene) conduit and pressure pipe for decades. We are active members of PPI (the Plastic Pipe Institute) including representation on the conduit division management and core technical committees. BDI is also active in ASTM (American Society of Testing and Materials). ASTM is the premier standards writing body for construction (and other) materials. Additionally, we are members of the IGSHPA (International Ground Source Heat Pump Association), which was the foundation for design, installation and licensing of the geothermal HVAC industry. On the construction side, BDI is an active member of the PCCA (Power & Communication Contractors Association).
Blue Diamond offers its technical expertise through links to the above entities, our own data sheets and technical notes. Finally, there is an "ask the expert" section, where we have answered frequently asked questions. Feel free to add to the list!
