n: the amount of force needed to crush the sides of pipe until it caves in on itself. The pipe collapses when the pressure outside it is greater than the pressure inside it.

n: The required pressure collapsing casing from outside.

external hydrostatic pressure that will cause the onset of pipe yielding. Heavily influenced by tension loads on the pipe.

the collapse pressure derated by a safety factor. Takes into account the effects of axial load. The formulas are only good for round pipe.
