How do I calculate the design pressure of a pipe given the norminal bore and thickness of the pipe?
Answer:
By design pressure, I assume you mean the pressure at which the pipe will fail. If that is the case, the formula to use is...
P = (2 * S * T) / ((OD - 2*T) * SF)
where P is pressure, S is the ultimate tensile strength of the pipe material, T is the wall thickness, OD is the outer diameter, and SF is the safety factor (set this to 1 for no margin of safety).
