Wall Thickness displayed are in inches,
weights displayed are in pounds/foot and
burst pressures displayed are in PSI.
Theoretical Bursting Pressure is based
on an ultimate strength of s=70,000 psi.
Using Barlow’s Formula where:
P = T2S / OD
T = Wall thickness When establishing a working pressure a
safety factor of 4 or 5 to 1 is
typically used, the joint efficiency is
in the 70% range and wall thickness
variations are 12.55 of normal. Factors
where calculated at ambient
temperatures.
