气密性试验通用规程
Air Tight Test Specification
一、总则 General

1、本规程适用于压力容器的气密性试验的操作过程管理。 This specification applies to control of air tight test during operation. 2、本规程对换热器的管程、壳程均适用。 This specification is applicable to tube side and shell side of the heat exchanger. 3、本规程同时适用于扬巴二期项目位号为 E-2300 的设备。 This specification is also applicable to the equipment (item no: E-2300) for IPS II project. 二、内容 Content

1、试验通用条件 General testing condition ⑴气密性试验应有专门的试验场地,并应有可靠的安全防护设施。 Special testing site shall be set for the air tight test, and safe guard facilities shall be furnished. ⑵ 试验用的工装应为经过设计、审核并验证过的合格工装。 Testing assembly shall be designed, reviewed and certified as per acceptable assembly. ⑶ 试验前连接部位的紧固螺栓必须装配齐全,紧固妥当。 Connecting parts shall be assembled with tightened bolts prior to testing. ⑷按工艺文件要求, 试验时至少应采用两个量程相同且经过计量校验合格的压力表, 并应安 装在被试验容器的顶部便于观察的位置。 As a minimum requirement, two pressure gauges with same measuring range and acceptable meter shall be used, and the pressure gauges shall be installed in a visible place for inspection. ⑸ 试验过程检查期间压力应保持不变, 不得采用连续加压来维持试验压力不变, 且试验过 程中不得带压紧固螺栓或向受压元件施加外力。
