Free online plastic pipe
pressure design software
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.”
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 principal authors of the PPI
project were Dr Lawrence and Dr
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).
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.

Cold-drawn precision steel
tubes from Switzerland
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).
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.
