Stresses and Strains in Main Gas Pipelines due to Ramifications

Abstract:

In this paper is presented a study of stresses and strains due ramification to consumers of main gas pipeline. It's numerically analyzed the influence of main pipe's ramification due to modification of mechanical and geometrical parameters. Modeled loads are based on evaluation of internal forces of thin shell and induced loads by circular weld thermal field. The study of stresses and strain it's made using finite elements method by a static tri dimensional analysis performed both for evaluation of stresses and strains in presence and absence of internal pressure. The obtained results represent a comparative factor for technical regulation in the safety assessment in operation of natural gas pipelines.
