换热管与浮动管板接头试压新法 浮头式换热器制造中 ,需对换热管与浮动管板(检测密封 1 )、浮头盖法兰与浮头管板 (检测密封2 )、管箱法兰与外头盖法兰 (检测密封 3)共 3个密封面进行水压检测。图 1所示为内浮头结构 ,且显示了上述需要注水打压检测的 3个密封面。图 1 内浮
Heat exchange tubes and floating tube plate joint pressure test The new method floating head heat exchanger manufacturing, the need for heat exchange tubes and floating tube plate (test seal 1), floating head flange and floating tube plate (test seal 2), pipe Flange and the outer flange (test seal 3) a total of three sealing surface for water pressure testing. Figure 1 shows the inner floating head structure, and shows the need for water injection pressure test of the three sealing surface. Figure 1 Floating
