Fiber welding of plate-fin heat exchanger
Welding of the fiber plate-fin heat exchanger, in addition to a collection box for both sides and weld thickness for surface crack detection, the main vacuum leak through the sides, respectively, to confirm their status. If the pressure test and found a leak,more easily found.
If leakage can be cut either side of the collection box, with another example of fillingpressure method, to identify the specific leak channel, for repairs to provide the correct basis. If the plate-fin heat exchanger is used for air separation plant in the main evaporator, in order to prevent the operation of liquid oxygen in the carbonmaterial should be kept within the plot is usually the oxygen leak channel blocked.Therefore, when conducting the leak. Channel should be inflated in nitrogen, oxygengas tank side of the cut set.
