What are the things to note when installing 6000 air separation units?

1. The internal pipelines of the cold box must be thoroughly degreased and protected, and any metal debris resulting from cutting must be removed carefully； 2. The walls of the cold box and its bottom must be welded tightly to prevent leakage and light penetration ； The grounding of the 3 cold boxes’ main towers and the argon towers should be separated from the lightning and static electricity protection grounding of the cold box walls, with connections made to different wires ； After cleaning away the metal debris, weld the 4 main towers together ； 5. Oil is prohibited in the fillers of air-cooled and water-cooled towers; crushing the fillers before installation is also forbidden ； 6. When loading the molecular sieve into the purifier, it should be done on a sunny day; the powder present in the molecular sieve must be removed, the filter screen of the bed layer must be secured properly, and the gaps should be filled tightly with asbestos rope ； Oil is strictly prohibited in the 7-oxygen pipeline and the pipelines leading to the air separation system ； This post was last edited by Longsky Eagle on 2009-2-14 09:15]
