products & developments Free online plastic pipe pressure design software

Standards used in PPI PACE include AWWA C900, AWWA C901, AWWA C905, AWWA C906, ASTM F714 and ASTM D2241. Input parameters include type of materials and pipe size, pipeline length, design velocity for recurring and occasional surges, working pressure, anticipated recurring surges, temperature and minimum design life. The software produces a summary report, as well as pressure and life charts comparing PE4710, ASTM-F714, PE4710 AWWA-C906 and PVC AWWA-C900, for example.

The Plastics Pipe Institute, Inc (PPI) has launched online plastic pipe pressure design software for water distribution, transmission main systems and force mains. The Beta version of PPI PACE (pipeline analysis and calculation environment) is available at www. ppipace.com “PPI PACE allows engineers and industry professionals to easily perform plastic pipe pressure pipe design calculations in accordance with current published AWWA and ASTM industry standards,” stated Tony Radoszewski, executive director of the PPI. “The web-based program will assist professionals in the selection of appropriate pipe class for the required design life by providing an easy-to-use tool that is consistent with these existing standards and practices. PPI PACE was constructed by two experienced and renowned engineers.”

“The principal authors of the PPI project were Dr Lawrence and Dr

In addition to BoreAid, PPI PACE can be used with the PPI Design and Engineering Calculator, another tool that assists in greater understanding of PE pipe capabilities. The calculator will assist a 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.

Knight, the same team that developed PPI-BoreAid and BoreAid™, the first comprehensive and preliminary HDD design tool for trenchless applications of PE pipe used in gas distribution, water and sewer systems,” said Mr Radoszewski. “PPI PACE is also able to provide the necessary information in a very expedient manner.” Dr Karl Lawrence is from eTrenchless Consulting Ltd (Ontario, Canada), and Dr Mark A Knight, P.Eng, is an associate professor and executive director of the Center for the Advancement of Trenchless Technology (CATT) at the University of Waterloo (also in Ontario).

Forster welded precision steel tubes range from outside diameter 16 to 76mm with wall thickness from 0.8 to 6mm; for cold drawn execution, outside diameters range from 10 to 60mm with wall thickness from 0.8 to 5.5mm. Forster Rohr- & Profiltechnik AG – Switzerland www.forster-rohre.ch

Forster manufactures welded and cold- drawn precision steel tubes in line with customer-specific requirements, according to EN 10305-2, EN 10305-3 and EN 10305-5. Where costly seamless or cold drawn tubes (EN 10305-1 or EN 10305-2) are used, Forster claims that it can, in many cases, offer cost saving for their welded alternatives (EN 10305-3).
