压力试验是检验压力容器整体质量的传统方法，也是对无法做无损检测的焊缝进行致密性检验的手段。《容规》[1]要求压力容器制成后应进行耐压试验，GB 150[2]则作出了实施细则，但对多腔容器的规定却不够明确，要求图样设计具体考虑并注明相应要求。为方便设计应用，以夹套罐下封头凸缘焊缝泄漏为例对罐体焊缝致密性检验的压力试验方案进行了分析讨论，并针对罐内设计压力的各种情况，分别给出了夹套罐压力试验的致密性检验模式。

Pressure test is not only a conventional method for inspecting pressure vessels total quality, but also a method for seal test of welds which cannot be examined by NDT. Pressure test shall be performed after the pressure vessel is fabricated, deifned by Supervision Regulation on Safety Technology for Stationary Pressure Vessel. GB 150 which has formulated the detailed rules for implementation, but provisions of pressure vessels with multiple chambers is equivocal, and the relevant requirements are regarded specifically and specified in design drawings in accordance with the relevant provisions. For the ease of design and application, take the welding seam leakage between bottom head and lfange of jacketed tanks for example, analyzing and discussing pressure test program for inspecting the compactness of tanks welds, and giving pressure test mode for inspecting the compactness of tanks separately, in allusion to all instance of in-tank design pressure.
