Rectification tower also is a kind of separate facility essentially, can use the different part in detached and different stock, but a bit must be remember well, no matter detached is which kinds of material, necessary test must have to equipment before the operation, the experiment basically included intensity and air-tightness two.
Usually, rectification tower makes manufacturer had had pressure test to its before leave factory, it is OK that air-tightness should be made experiment only below eligible circumstance. But injure a trace or the spot has been made local change one’s costume or dress; Also or the time of park is too long, pressure test also is indispensable. Commonly used pressure test method is hydraulic law, be in only face unfavorable baric method just can be used when making the equipment with medium or sophisticated structure with water, rectification tower is such. Had done reliable safety precaution even at the same time, consider to undertake after the decision via concerning a section. Additional, the pressure that the pressure test of equipment and air-tightness experiment and stop press time to have strict regulation, must accord with the standard of design or equipment technology file, make sure experiment process safety is effective.
