Corrosion protection for instrument trays
Thread Content
After several years of use, rust spots appear on instrument cable trays. I wonder at what extent these rust spots need to reach before it is necessary to apply anti-corrosion treatment to the entire tray Here, both the power and instrumentation cable trays have been in use for over a decade now; there are many rust spots on them, but no one seems to have mentioned it, as if there’s no plan to address it. What should be considered when formulating an anti-corrosion plan for cable trays? How to prevent cables from being contaminated by paint? Does benzene in paint corrode the cable insulation?
You can ask a professional anti-corrosion company to develop a plan
1# nihaomaaa This is a rather technical issue; corresponding anti-corrosion measures should be taken during the construction of the instrument panel. Of course, the anti-corrosion effectiveness may decline over several years, so remedial actions are necessary. It seems that corrosion prevention isn’t a one-time solution……
We use fiberglass trough boxes that are fully sealed to prevent corrosion of the cables and cable trays
If there are corrosive gases in the area, shouldn’t the metal cable trays also be coated with protective paint in advance? Moreover, it is the outer surface that is brushed; how could it be corrosive to the cable? As for repainting, the cover plate should also be in place before painting; it can be removed in advance for painting and then put back on afterwards. As for whether benzene reacts with polyvinyl chloride or rubber, one would need to consult experts in the relevant field
The cable trays have been treated for corrosion before leaving the factory, in accordance with certain GB standards; however, after several years or even a decade of exposure to wind, sun, and rain, many of them develop rust spots, some of which appear in large areas. There are those on the outside and those on the inside. The ones on the outside are easier to deal with – after removing the rust, just apply some paint and that’s it. But what about those on the inside? With so many cables, how to remove rust? And I’ve heard many people say that benzene in paint is highly corrosive to the outer coating of cables, so there’s a fear that the cables might come into contact with paint or be damaged by its volatile substances.
