    • The invention relates to the integrity testing of a heat exchanger (1) having a high-pressure section (2) and the low-pressure section (3). By using valves (5), (6), (11) and (12) it is possible to isolate the heat exchanger from the larger system or plant in which it is incorporated. Having isolated each section from the larger system the high-pressure section (2) is pressurised while maintaining the low-pressure section (3) at atmospheric pressure. Then after a preset time the pressure in the low-pressure section (3) is measured and if it has raised there is a leak. Similarly measuring a pressure drop in the high-pressure section (2) will provide the same result.
    • 本发明涉及具有高压部分(2)和低压部分(3)的热交换器(1)的完整性测试。 通过使用阀(5),(6),(11)和(12),可以将热交换器与其并入的较大的系统或设备隔离。 从较大的系统分离每个部分,高压部分(2)被加压,同时将低压部分(3)保持在大气压力。 然后在预设时间之后,测量低压段(3)中的压力,并且如果它已经升高,则存在泄漏。 类似地,测量高压段(2)中的压降将提供相同的结果。
