Fatigue behaviour of X70 steel in crude oil

Popis výsledku v původním jazyce

The fatigue properties of the X70 steel in crude oil and in the water separated from the crude-oil phase were tested, the stress-cycle-asymmetry ratio being R = 0. As a reference, fatigue tests in air were also carried out. The fatigue specimens used were prepared from the Vohburg an der Donau ? Nelahozeves (IKL) crude-oil pipeline after 13 years of exploitation. The tests were aimed at assessing the degree of degradation of the fatigue properties of this steel due to the environmental impacts typical for the crude-oil processing and transport. For added value, fatigue tests were also carried out in an alkaline solution on specimens prepared from a new pipe. The results of the tests showed that the fatigue properties of the steel in crude oil were slightly better than in air, but much poorer in the water separated from the crude-oil phase.
