PPI Calculators

PPI-PACE

Follows applicable standards from ANSI/AWWA
Aids in selection of HDPE pipe for pressurized water distribution and transmission systems
Accounts for recurring and occasional transient surges and the design fatigue life of the pipe
Provides comparable calculations for PVC and ductile iron pipe following applicable standards
PPI-PACE is provided by eTrenchless Group Inc.

Follows ASTM F1962 Standard and The PPI Handbook of Polyethylene Pipe, 2nd edition
Designed to assist in the evaluation of HDPE pipe for installation using Horizontal Directional Drilling (HDD)
Employs the calculation and framework developed in BOREAID™
PPI-BoreAid is provided by eTrenchless Group, Inc

Uses the General Flow Equation to calculate gas flow in polyethylene pipe
Applicable to gas flow in any pipe as long as the correct pipe roughness and internal diameter are entered
Will solve for remaining variable if 4 out of 5 variables are entered (Pipe Length, Pipe Internal Diameter, Inlet Pressure, Outlet Pressure, Gas Flow Rate)

Determines the pressure required to test for leaks in for plastic gas distribution pipe as per US Federal Code Title 49 Part 192.513
Users of this calculator must have knowledge of the PPI TR-4 HDB values and requirements under §192.121 for the material selected for test
In Federal Code 140°F is the highest recognized temperature for an established HDB. If plastic pipe temperature is above 140°F at the time of test or if the minimum test pressure exceeds the maximum allowed test pressure, the test should be delayed until the pipe cools.

Applicable to: HDPE Conduit, mini-HDD
Provides recommended wall types for mini-HDD installations
Takes into account installation routing and bends
Limits are 15ft deep, 1000 ft pull
Go to ConduitCalc.com for more information and to use the calculator
The Calculator is easy to use, but we have a free PPI eLearn Short Course that demonstrates it.

Aids in designing plastic pressure pipe and tubing systems using CPVC, HDPE, PEX, PE-RT, PP-R and PP-RCT materials
Utilizes dimensional data from ASTM International and CSA Group industry standards for these piping materials, as well as data gathered from various PPI research projects and publications
Intended to assist designers using these materials for applications such as plumbing, water service, fire protection, hydronic piping (liquids), radiant heating & cooling, snow & ice melting, geothermal ground loops, district heating, and turf conditioning
Main functions include: Pressure/Head Loss, Pipe Weight/Volume, Thermal Expansion/Contraction, Hydraulic Shock, Expansion Arm/Loop, Static Water Column Pressure
This Calculator from BCD is easy to use, but we have a free PPI eLearn Short Course that demonstrates how to use the calculator.
