Use McElroy's fusion pressure calculator to quickly find the right fusion pressure for your job. To properly fuse pipe the fusion pressure must be adjusted so the pipe manufacturers recommended interfacial pressure is achieved.
We have several convenient ways to calculate fusion pressure. You can use our online tool below, download the Fusion Pressure Calculator App for your mobile device, or order a sliding calculator.
Wondering how it all works? Learn how to calculate fusion pressure.
Using a 28 Machine from Chart A (at right) we will determine our gauge pressure.Pipe Size = 8" IPS
|Model||High Force Standard||Medium Force High Velocity||Low Force Extra High Velocity|
To determine wall thickness we will be using the Example (above).
T = OD
= Wall thickness
Now the Example and the formula above we will calculate the wall thickness.
T = 8.625
Use Chart A (above) to find the TEPA of your machine.
TEPA = 4.710 (we are using the 28 as an example)
Using the information we have gathered from above.
(OD - T) x T x PI x IFP
+ DRAG = Gauge Pressure
Now using all the information and the formula above we will find the gauge pressure.
(8.625 - .784) x .784 x 3.1416 x 75
+ 30 PSI = 338 PSI
