"Обычно давление в "трубном"腔室"施加，有些一些特殊部位需要对两个腔室都进行压力测试。我们一个高压水冷设备在进行压力测试时只对"管程"腔室施加压力 "水压"较低但是"壳程"腔室在开工后泄漏了 "壳程"工作压力为70多磅。今年检修时我们对高压"换热器"设备的"管程"和"壳程"腔室一起进行了压力测试。"

"Тестирование压力一般在"管程"进出口处安装盲板 "管程"腔室灌满水后利用加压泵施加至工作压力的1.25倍保持半小时无无泄漏即可。如果如果"壳程"腔室的工作压力较高 "壳程"腔室也有进行压力测试的必要 "施加至工作压力的"吨.22倍。"

"Если只是"管程"循环水检修了 "就只需要对"管程"腔室施加压力 "前提是检修的位置与"壳程"腔室毫无关系（无筒体无管板等修改) 且为还原原设计的修整。"
