Hi all,
In fact, i'm not a CP/corrosion engineer but i want to show you, in the attached graphic, my visualization of a typical 4'' pipeline cathodic protection system, that will be installed in my next project.
The installation will not include sacrificial anodes, which will be implemented in a latter phase (because it require a couple of studies),but it only englobe the provision & cabling of test stations, reference electrodes (cu/cuSO4) and the DC negative connections/cables.
Related to this, i have a couple of questions:
1)firstly, Please give me your general comments/advices/feedback about the reperesentation.
2) Concernning the connections:
-pipe-Junction boxs
-CP test station-reference electrode
- CP test station-pipe
I have chosen an XLPE/PVC cable type with section area equal to 6 mm2. does that section/cable type, fit the anode current/voltage ratio = 15A/3000 mV ?
3)According to your experiences, wath are the nominal distances (cables lenghts) should be considered between the test station-Pipe and the test station-reference electrode.
4)Can I Connect more than one pipe to a single junction box, if their risers are close to each other ?
5) Similarly, Can i connect One TEST STATION (with one reference electrode) to 2 or more risers pipes if they are in front of each other
Thank you in advance, And sorry for the long queries
