Hello Experts,
First of all, my apologies if this belongs in the wrong thread; I feel like it borders between Mechanical and Electrical.
I'm a long time reader and usually am able to find my answers searching through these forums but I have looked everywhere and haven't found any useful info so I'm hoping someone may be able to help me out here.
I'm working on a project where several hundred feet of 24" A106-B Cooling Water Piping is being replaced due to soil/air interface corrosion. Some of the wasted pipe runs just below/adjacent to a T&D cable tray conveying high voltage cables. The piping is fitted with a thin welded pad and three identical grounding lugs welded on top of that plate. My guess is that because of the proximity to the cable tray, the original designer was concerned about a voltage being induced on the pipe from the cables and placed the grounding lugs to prevent any static charge build up.
My issue is that I've read about grounding requirements for equipment but I can't find anything in the Owner's standards or in relevant Code that talks about requirements for grounding pipe. Hoping someone can provide me any info that'll send me in the right direction.
Picture of the lugs here:
Thank you,
SMEIT
