Problems with the installation of lighting in chemical processing plants
Thread Content
Let’s discuss how to carry out rainproofing at the pipe connection points for lighting installation in chemical plants Are there any regulations in this regard?
I also want to know if there are any regulations in this regard. Waiting for the expert's reply. There is also water ingress in our device.
Use an explosion-proof union! If pipes are run directly through the cable tray, it is also necessary to prevent water from entering the cable tray
On a regular pipeline rack, just tighten it. At the backup connection point, pay attention to the wiring (such as bending it upward) to prevent water from entering.
When explosion protection is not required, drainage ports are provided at the bottom of each junction box
Anti-riot junction boxes have sealing rubber rings, right? . Pay attention to potential issues related to pipeline anti-corrosion
Of course, it must be installed in accordance with the explosion protection rating.
Of course, it would be ideal to ensure that everything is sealed during construction and that no materials or components are damaged, but this is very difficult to achieve in practice. As a result, water seeps into various junction boxes, and even mild moisture can easily lead to ground short circuits. Therefore, when no explosion-proof requirements apply, it should be changed to a drainage outlet, avoiding the connection point for the incoming wires.
