ABSTRACT:
A method of performing hydraulic pressure test of tubes includes the step of performing hydraulic pressure test of the tube. The ends of a test tube are sealed by using closing caps at the respective opposite ends of the test tube which has been filled with water under a completely air-purged condition. The closing caps are held in place during conveyance of the test tube with the opposite ends thereof sealed by the closing caps, to a position at which the test tube is subject to the steps of a hydraulic pressure test including sealing to prevent the filled water from leaking; introducing high pressure water in the hydraulic pressure test step with the closing caps attached to the test tube; maintaining the inner high pressure of the test tube due to the high pressure water; reducing the inner pressure of the test tube through the closing caps, upon the completion of the hydraulic test; and removing the closing caps from the test tube.
