COMPREHENSIVE CALCULATION METHOD FOR ASSESSMENT OF GAS TRANSPORTATION SYSTEM OPERABILITY

Abstract

The kinetics of the occurrence and development of damage in separate sections of the gas transmission system, 80% of which are fatigue related, is considered. The factors and cases of their impact in different numbers and comparisons are classified. Based on the completed fatigue tests, the equations of fatigue curves have been obtained and three calculation schemes were made up by classifying the affecting factors: and the corresponding nomograms are designed, by is possible to obtain updated values of parameters of factors and carry out reasonable calculation procedures.
