The classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is given in Eq.(1.6): (1.6)σh=Prt whereP, the internal pressure;t, the wall thickness;r, the radius of the cylinder. ...
The hoop stress σh in a pipe can be determined by the equation [2.6]σh=(pi−pe)(D−t)2t where σh = hoop stress pi = internal or external design pressure pe = external design pressure D = nominal outside diameter of pipe t = minimum pipe wall thickness For relatively thick-w...
11(a)) as a function of the average hoop stress, h , which was calculated by treating the tube as an thick-walled cylinder using the Lamé equa- tion, with radial integration of the hoop stress, h, h = ri2P r02 − ri2 1 + r02 r2 (2) where r is the radius, ri is ...
