Pipe radial expansion due to internal pressure
Pipe radial expansion due to internal pressure
(OP)
I would like to calculate the increases in internal diameter and external diameter in a pipe full of water when the pipe is pressurized.
Could anybody provide the formulas or advise where I can find them?
The ratio R/t is 8.625.
Thanks

With r/t>5 Hoop stress can be taken as pressure*radius/thickness

If the pipe is out-of-round, it will tend to round up when pressurized.

If your pipe wall is more than 1/10 of the radius which I suspect it is then you need to use Thick Walled Cylinder Theory see page 6 of this link titled "Constitutive Equations".
