Abstract

A bolted flange joint assembly is a complex mechanical device, according to ASME PCC-1. A complex mechanical device’s reliability depends on many activities being performed prior and during the assembly of the bolted flange joint assembly (BFJA) being assembled. Some of these activities being; required torque calculations; gasket material selection, fastener selection, type of flange, fastener condition, lubrication, and maybe the most important activity being the assembly of the bolted flange joint. How does one ensure the correct methods and best practices being used during the assembly of the bolted flange joint?

Education. Educating not only the assemblers but also the engineers, supervisors, foreman, etc. By educating more than just the assemblers we can create a proper culture to ensure BFJA reliability. We can quantify increased BFJA reliability spurred from education by using surveys completed by the assemblers who have gone through the training.
