Three‐point bending test is a common test for the pipes produced according to ASTM 335. This standard defines the bending test only for certain geometries of pipe. Due to the fact that this test is more and more required and also for “not” in standard defined sizes, and only few practical, industrial experiences exist in this field, the aim of this work is to correlate some simulations with experimental results. Systematic investigations of the influence of mechanical properties and geometry of the seamless pipe are performed. The influence of the testing parameters during the bending is investigated as well and presented in this paper. It is found that strength level, that is, yield strength to tensile strength ratio, has a strong influence on the evolution of stresses during the bending. Geometry of the pipe, in the range of investigated sizes, has not a crucial influence but defines the outside/inside area, in other words a sensitivity of tested samples.
