Abstract
In the present paper is presented a theoretical research about the lifetime determination of cylindrical pressured vessels with errors of construction. It's a matter of the eccentricity error between the cylinders from which is formed the body of vessel. In the same time is taking into account the crack presence in the thermal influenced zone of welding joint and of the fatigue conditions work of vessel, which is stressed with a pulsating cycle.
