腔室最高工作绝对压力的 1.5 倍；

b) 试压腔室的工作温度大于或等于 350 ℃时，壳体完整性水压试验的试验压力为腔室最高工作绝对压力的 2

倍。壳体结合面完整性水压试验的试验压力为腔室最

高工作绝对压力的 1.5 倍(见附件 1和 2)；c) 壳体试压腔室的工作绝对压力低于大气压时，排汽缸的试验压力为 0.2 MPa（g），其它壳件的试验压力为 0.14MPa（a）；

d) 平衡管的试验压力为 6 MPa（g）。

4.1.2 水压试验应在试压腔室机械加工完后、涂漆之前进

行。

4.1.3 汽缸在做壳体完整性水压试验时，允许在中分面结

合处使用垫片。汽缸在做壳体结合面完整性水压试

验时，允许在中分面结合处涂密封胶，但不得使用

垫片。

4.1.4 如果在做壳体完整性水压试验时不使用垫片，则该

试验可同时替代壳体结合面完整性水压试验。

4.2 试验准备工作

4.2.1 各部件的紧固件螺栓应装配齐全，螺栓紧力应均

匀。当采用电加热或液压拧紧螺栓连接的壳体，应

使用本身的联接螺栓，其预紧力应符合规定的要

求。

4.2.2 试验前，应对指示压力表进行检验，确认其已被检

定，并在规定有效期内。

为了确保试验正确，应安装两只压力表。压力表的量

程为试验压力的两倍为宜，但不得低于试验压力的 1.5

倍。

a) When the working temperature of the pressure testedchamber（herein the steam casing and the exhaust casing, thesame as below）is below 350℃, the casing test pressure shallbe 1.5 times of the maximum absolute working pressure of thechamber.b) When the working temperature of the pressure testedchamber is above or equal 350℃, the test pressure of the casingintegrity hydraulic test and the casing joint face integrityhydraulic test shall respectively be 2 times and 1.5 timesof themaximum working absolute pressure of the chamber .(refer toannex 1 and 2)c) When the absolute working pressure of pressure testedchamber of casing is less than the atmospheric pressure, the testpressure of the exhaust casing shall be 0.2MPa (g) and of theother casing 0.14 MPa (g).d) The test pressure of the balancing pipe shall be 6 MPa (g).

4.1.2 The hydraulic test shall be done after machining andbefore painting of the pressure tested chamber.

4.1.3 During the casing body integrity hydraulic test of thecasing, gaskets is allowed to use on joint of split. During casingbody joint integrity hydraulic test of the casing, sealant isallowed to coat on split joint, but gasket shall not be used.

4.1.4 If gasket is not used during the casing body integrityhydraulic test, thus this test may simultaneously substitute thecasing body joint integrity hydraulic test.

4.2 Preparations for test

4.2.1 The fastening bolts shall be completely assembled foreach component and the bolts shall be evenly tightened. If thebolts connected casing body is tightened hydraulically orthrough electric heating, its self connect bolts shall be used andits pre-tightening force shall meet the specified requirements.

4.2.2 Before the test, the indication pressure gauges shall bechecked to ensure that they have been checked and within thespecified valid period.In order to ensure correct test, two pressure gauges shall befitted. The range of the pressure gauge shall better be two timesof the test pressure but shall not be below 1.5 times of the testpressure.
