Evaluation of strength reliability of an oil-and-gas pipeline wall

Аннотация

As a result of the probability solution of the condition that the ring stress is lower than the limit stress, the fourth-order algebraic equation for determining the expected value of the wall thickness for the case when the initial parameters are normally distributed has been obtained. The sensitivity of the reliability of an oil and gas pipeline to the variations in the pressure, strength limit, diameter, and wall thickness has been studied, which improved its operation safety.
