Non-Destructive Testing of Coalescer Elements ON A Continuous Basis Using Liquid Crystals.

Abstract

A non-destructive test, for 100% inspection of coalescer elements was developed using liquid crystals as the flaw-detecting agent. Thermal changes associated with material defects are detected by the liquid crystals through a pattern of vivid colors encircling the defect. Liquid crystals can detect flaws in coalescer elements in the form of voids, split seams, end cap leaks and cracks, meterial imperfections and epoxy filled voids. (Author)
