PACE+ design tool

HDPE Pipe technical guidance (High quality Polyethylene Pipes)

PACE+ is an online tool developed for and released by the PE100+ Association.

The purpose of this tool is to assist industry professionals in the evaluation and selection of PE100+ pipe for pressurized water distribution and transmission main systems by completing design calculations. In addition to operating pressures, PE100+ PACE considers recurring and occasional transient surges and the design fatigue life of the pipeline in the evaluation process. The calculation methodology of PACE+ is an implementation of the existing standards (IGN 4-37-02 / IGN 4-32-18 / EN 12201-2 / ISO 4427-2) provided by eTrenchless Group Inc, and initiated by PPI.

This website is constructed to assist water distribution professionals in the selection of their product pipe by providing a pressure pipe design tool that is consistent with the existing standards. For polyethylene pipe, IGN 4-37-02 "Design Against Surge and Fatigue Conditions for Thermoplastic Pipes", IGN 4-32-18 "The Choice of Pressure Ratings for Polyethylene Pipe Systems for Water Supply and Sewerage Duties", EN 12201-2 "Plastic Piping Systems for Water Supply. Polyethylene (PE) Pipes", and ISO 4427-2 "Plastic Piping Systems - Polyethylene (PE) Pipes and Fittings for Water Supply - Part 2: Pipes" are the applicable documents. These are preliminary calculations only. Qualified professionals should be contracted to consider all aspects of a design.
