Abstract
This paper reports on numerical and experimental work concerning the fatigue behaviour andsealing capacity of threaded pipe connections (1” API Line Pipe). Numerical simulations are performedusing Abaqus®in combination with ThreadGen©. The fatigue life of a thick-walled standard coupling isdetermined using a four-point bending test. The corresponding S-N curve is compared to results of previouswork on thin-walled specimens. It can be concluded that the standard thick-walled connection has a higherfatigue life than thin-walled ones. In future work, the prediction of fatigue life using established multi-axialcriteria will be evaluated. Further, the sealing capacity of several couplings will be investigated bysubmitting them to different combinations of internal pressure and axial force. Hereto, a specific test setupis designed. The results will then be presented as a test load envelope
