COMPARATIVE ANALYSIS OF METHODS FOR STRENGTH CALCULATIONS OF T-JOINTS IN PROCESS PIPELINES

摘要

The results of analytical calculations of T-joints in process pipelines in conformity with GOST 32388-2013, GOST 34233.3-2017, and ASME B31.3-2002 regulatory documents are compared. A numerical study of stresses at T-joints was conducted using finite-elements method. Data were obtained on the influence of dimensions of cover rings on reinforcement of T-joint in pipelines. The results of numerical and analytical calculations of T-joints are compared.
