The value of airtight shall be betwee n 0.4MPa and0.5MPa.容器上的补强圈应通入0.40.5 MPa的压缩空气对所有焊缝连接部位进行气密性检查合格4.Preparati on for Test ing 试验准备4.1 Vents shall be provided at all high poi

9、nts of the vessel in the positi on inwhich it is to be tested to purge possible air pockets while the vessel is being filled.容器顶部所有高点都应设置排气口，以便于充水过程中将容器内部的空气排放干净。4.2 Prior to hydrostatic pressure test, the in side and outside of the vesselshould give a good clea ning to remove oil, grease, paint and

10、 other dirt. The exam ined area of the in side and outside of the vessel shall be kept clea n, without any dirt which in fects the test. The surface must be dried. In ter nal In specti on Report should be submitted for approve.水压试验前，容器内、外应清理干净，清除所有的油污、铁锈等污垢。试验过程中所有试验范围内的容器内、外表面应保持干净，没有影响试验的污物。容器的外表面

11、必须保持干燥。容器内部检查报告应提交 批准。4.3 Before applying pressure, the test equipment shall be examined to see that itis tight and that all low pressure filli ng lines and other appurte nan ces thatshould not be subjected to the test pressure has bee n disc onn ected.水压试验前，应检查试验设备是否连接紧固，检查所有不属于试验系统的低压填充物及其它附属物是否已经

12、分离。4.4 Before applying pressure, the temperature of the test medium and the wall temperature of the vessel shall be measured with the thermometer. The test pressure shall be applied after the vessel and its contents are at about the same temperature.水压试验前，应采用温度计测量试验液体和容器器壁的温度。当容器壁温与试验液体温度一致时，方可对容器进行
