Flange design conception: flanges of inverse flexion

摘要

A flange design conception is disclosed. The conception relates to the flanges for making leak-tight flanged connections between component parts of pressure vessels, piping systems, boilers, reactors, heat exchangers, and the like. By providing inverse flexion of the flanges during the fastener preload the invention increases the leak tightness of the flanged connections under conditions of high internal operating pressure.
