Comparison of stresses showed that the APILT and C 8 Round threaded casing connection could be accurately analyzed with finite element methods, with models that both included and excluded the threads. This article investigates the effects of thread tapers and external loads on connection stresses. It also assumes a criteria for determining maximum assembly interference using the finite element models. Tension loading is shown to affect pin hoop stresses, while being insignificant to coupling hoop stresses. Hand-calculated stresses are shown to give reasonable hoop stress values.
