HIGH TEMPERATURE TUBE BURST TEST APPARATUS USING HYDRAULIC PRESSURE AND BURST TEST METHOD USING THEREOF

摘要

The present invention relates to a high temperature tube burst test apparatus using hydraulic pressure, and a burst test method using the same. The high temperature tube burst test apparatus using hydraulic pressure comprises: a housing having an internal space in which a test target tube is installed; a pressing unit connected to the tube by a supply pipe, injecting pressurized water inside the tube to increase an internal pressure of the tube; a pressure measurement device installed in the tube or the supply pipe to measure the internal pressure of the tube; a heating unit heating the inside of the housing to a set temperature to enable a burst test to undergo at a high temperature state; a hydraulic pressure maintaining unit installed in the supply pipe, and maintaining internal pressure of the tube at a set pressure equal or higher than a saturation vapor pressure of the pressurized water at the set temperature when the inside of the housing is heated to the set temperature by the heating unit; and a pressure storage unit storing pressure data measured by the pressure measurement device. In the high temperature tube burst test apparatus using hydraulic pressure and the burst test method using the same in accordance with the present invention, since the heating unit heating the housing in which a test sample is installed is provided to allow a burst test to be conducted at a high temperature environment; a burst pressure of a tube operated in a high temperature high pressure environment such as a nuclear power plant is possible to be measured. Moreover, since pressure within the test sample is uniformly maintained during a process of heating the test sample by the hydraulic pressure maintaining unit, a tube burst test using hydraulic pressure is able to be conducted, and a burst phenomenon which may occur in a tube to which hydraulic pressure is applied at high temperature and high pressure in actuality is able to accurately be simulated.
