Design of PE Piping Systems - Plastics Pipe Institute

Design of PE Piping Systems 159 The Hydrostatic Design Stress, HDS, is the safe long-term circumferential stress that PE pipe can withstand. It is derived by applying an appropriate design factor, DF, to the Hydrostatic Design Basis, HDB. The method for establishing the Hydrostatic Design Stress for PE pipe is described in Chapters 3 and 5.

Ground Loop Piping & products - Martin Energetics

The HDPE pipe that goes underground must be connected to a closed, circulating loop, no matter what it's deployment borehole, trench, field, or underwater. This means that the conducting pipe runs need to be connected to header supply and return pipes that convey the brine to the heat pump and back. And that requires pipe joints along the path.
