Experimental Research on the Performance of Common Mechanical Seal Gaskets

　2017-01-05　　

Experimental research on the performance of commonly used mechanical seal gaskets. This aspect has always been a weak link in the past, and the research on mechanical seal gaskets has only been strengthened in recent years. For example, the University of Petroleum, on the basis of reference to the American ASTMF586-79 standard and the A and B test methods recommended by the American Pressure Vessel Research Committee (PVRC), has tested winding, oil-resistant asbestos rubber, metal coating, pure and framed expanded graphite , Octagonal and metal ellipse gaskets have been studied, a lot of test data have been obtained, and various characteristic curves have been plotted. On this basis, the structural dimensions, scope of use, manufacturing requirements and sealing parameter values u200bu200bof various gaskets are pointed out. A new method of sealing design for flange connection and the tightness criterion of flange connection of petrochemical equipment are recommended.　　225.html,
