HIGH-TEMPERATURE CREEP INTERNAL PRESSURE BURST TESTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a high-pressure creep internal pressure burst testing apparatus capable of easily, efficiently and evenly heating even a large test piece, facilitating checking of internal pressure to allow for accurate measurement and control, facilitating handling of cores, and reducing the heat capacity of the cores. ;SOLUTION: The high-temperature creep internal pressure burst testing apparatus has attached to each end of a tubular testing part a lid for closing a hollow space in the tubular testing part, and pressure introducing parts are provided on the lids. At the pressure introducing parts, pressure within the hollow space is measured and a pressure measurement control device which controls the pressure within the hollow space from one of the pressure introducing parts according to the measurement result is provided in connection with each pressure introducing part. Cores are packed into the hollow space, and a heater divided into three or more along the direction of the tube axis of the tubular testing part is disposed around the tubular testing part. Further, the tubular testing part is formed as a curved tubular testing part or the heater is in the form of a plate or folded plate divided into three or more in the direction of the tube axis and into four or more in the circumferential direction of the tube.;COPYRIGHT: (C)2001,JPO
