ANALYSIS OF PERFORMANCE OF THE NEW TYPE OF FOUR EQUAL OF THE INJECTION ONLINE PRESSURE SEALING FIXTURE
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Taking the leakage of steel pipe welding neck flanges with raised face as the research object, the structural characteristics of the traditional fixture and new type of four equal fixture were investigated, and the mechanical properties of the traditional fixture and the new type of four equal fixture were analyzed by using the finite element software Abaqus. The results show that, in the case of the same internal uniform pressure applied to the two kinds of flanges, the maximum circumferential tensile stress and the maximum tensile stress of the bolt of the new type of four equal fixture is 42.2% and 42.9% for the traditional fixture, respectively. The new type of four equal fixture is superior to the traditional fixture in both pressure bearing capacity and stress concentration. Therefore, it is of great significance to investigate the mechanical properties and concept design of the new type of four equal fixture for the wide application of pressure sealing technology
