Project Design, Planning Software Aids Available

The Plastics Pipe Institute Inc. (PPI) has 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.
