Strength Reliability Computation for a Beam Section of a Main Gas Pipeline

Within the framework of the theory of random values, a formula for the index of the static model of the strength reliability of a beam section of a pipeline is obtained (the probability of indestruction) in the case where the physical and mechanical characteristics of pipes, the load in the bearing structures, the internal gas pressure, the pipe wall temperature difference, the pipe diameter, and the pipe wall thickness are normally distributed. Optimal characteristics of pipeline reliability are obtained at the design stage such that the failure-free operation of the gas pipeline section on equidistant bearing structures is ensured for the service life limit.
