CLOSING APPARATUS FOR TESTING PIPING WITHSTAND PRESSURE, AND TOOL FOR TESTING PIPING WITHSTAND PRESSURE

摘要

PROBLEM TO BE SOLVED: To provide a closing apparatus for testing piping withstand pressure used for closing of piping in testing piping withstand pressure, by which problems such as limitation of application of internal pressures for testing and complexity in its structure are solved.;SOLUTION: The closing apparatus 1 for testing piping withstand pressure comprises a pair of tools for testing piping withstand pressure 2a, 2b. The pair of tools for testing piping withstand pressure are provided inside a pipe 4 in a connected state with each other with a connecting component 3, and each of the tools is brought into close contact with an internal surface of the pipe to close a section 6 to be tested for the testing of withstand pressure.;COPYRIGHT: (C)2009,JPO&INPIT
