Wall thickness displayed are in Inches, and Weights displayed are in pound/foot. Theoretical Bursting Pressure is based on an ultimate strength of s=70,000 psi. Using Barlow’s Formula where: P = T25/OD
T = Wall thickness When establishing a working pressure a saftey factor of 4 of 5 is typically used, the joing efficiency is in the 70% range and wall thickness variations are 12.55 of normal. Factors where calculated at ambient temperature.
