FLANGE LEAKAGE INSPECTION APPARATUS AND FLANGE LEAKAGE INSPECTION METHOD

摘要

Disclosed are a flange leakage inspection apparatus and a flange leakage inspection method to inspect leakage generated in a flange. The flange leakage inspection apparatus may include a chamber which has a sealed space wherein the flange is accommodated; a gas supplier which provides a high-pressure gas in the sealed space; a heating element arranged around the flange; a thermal image detector which detects heating element temperature change and produces a temperature distribution image; and a controller which analyzes and determines flange leakage using the temperature distribution image produced by the thermal image detector.;COPYRIGHT KIPO 2014
