Method and system for producing stress corrosion cracking

摘要

A method and system for producing stress corrosion cracking (SCC) is disclosed, wherein the method is employed to cause the inner wall of a tube specimen to generate stress corrosion cracks while applying a pressure difference and a temperature difference between the inner and outer walls of the tube specimen. The system of the invention comprises: a tube, having an enclosed space formed therein for receiving a solution; and a heating apparatus, capable of heating the tube continuously until the outer wall of the tube reaches a specific operating temperature; wherein the inner wall of the tube is subjected to a specific operating pressure while the outer wall of the tube is maintained at the specific operating temperature by the heating apparatus. The present invention can accelerate stress corrosion cracks to be generated on a specific tube by means of manual simulation, so that the evaluation of crack depth on the inner wall of a tube through the testing of tube specimens with stress corrosion cracking, which is made out of the specific tube, can be improved on both inspection reliability and accuracy.
