CURVED-TYPE TENSION TEST APPARATUS FOR PIPE WRECK TEST

摘要

PURPOSE: A curved tension testing device for a destructive test of a pipe is provided to obtain the directivity of cracks by eliminating effects of the moment actuating on a curved testing piece, thereby improving the accuracy of a destructive test by applying a uniform distributed load to a thickness direction of the testing piece. CONSTITUTION: A curved tension testing device for a destructive test of a pipe comprises a tension testing piece(20), pin holes, and a multi-stage fixing pin(200). The tension testing piece comprises a cut unit. The pin holes are bored in both sides of the tension testing piece around the cut unit. The fixing pin is fitted into the pin hole.
