WebFormula for estimate the hoop stress of a cylinder is, Hoop stress = Internal diameter x Internal pressure/2 x Thickness. Mathematically hoop stress can be written as, σ θ = P.D/2t. Where, σ θ = Hoop stress in the direction of the both and unit is MPa, psi. P = Internal pressure of the pipe and unit is MPa, psi. WebThe hoop stress depends upon the way of the pressure gradient. The reason behind the hoop stress is, when a cylinder is under the internal pressure is two times of the …
