Free online programs assist in planning PE pipe systems
The Plastics Pipe Institute Inc. (PPI) added two new online software aids to assist in the design and installation of polyethylene (PE) pipe.
The PPI-BoreAid software simplifies the design process of complex calculations for trenchless applications of PE pipe used in gas distribution, water and sewer systems. Project and pipe details can be entered into the PPI-BoreAid tool to assess deflection, critical collapse, pull back force and allowable pullback force.
The PPI Design and Engineering Calculator makes available to engineers a tool that assists in greater understanding of PE pipe capabilities. Specifically, the calculator will assist the design engineer in performing multiple computations relating to internal and external pressure ratings, pressure and gravity water flow, water hammer, low pressure and high pressure gas flow, and automates other assessments for above and underground systems. Both of these design tools can be found on the PPI’s website homepage at www.plasticpipe.org.
Both the PPI BoreAid and Design Calculator are applicable for use in analysis and design of PE pipe systems for fuel gas lines or for municipal pressure and non-pressure applications.
The PPI-BoreAid tool facilitates in the design process as outlined in PPI’s Handbook of Polyethylene Pipe, Chapter 12, which supplies guidance in horizontal directional drilling (HDD) projects in accordance with the ASTM F1962 standard. It employs calculation methodology and framework as developed and used in BoreAid, a more comprehensive HDD design tool that can be
