Corrosion of buried pipeline
Corrosion of buried pipeline
(OP)
There is pipeline of 30inch diameter buried not ( not insulated and no cathodic protection on it) and there are electrical cables beside it
Is there effect of electrical cables on corrosion rate of pipeline and how can this pipeline be repaired when leak happen what is the recommended practices ?

RE: Corrosion of buried pipeline
That's a darn basic question. Hire an expert to develop a corrosion plan for you.
RE: Corrosion of buried pipeline
There are many ways to repair a leaking pipeline depending on type of damage, extent of damage, contents, pressure rating etc
A pipeline with no coating(?) and no CP in a damp soil environment has a limited life span and extensive external corrosion will require replacement much sooner than a coated pipeline with CP protection.
Not many (any) details from you means that responses are also suitably limited.

RE: Corrosion of buried pipeline
how can I make cathodic protection on it and how many no of sacrificial anodes?
RE: Corrosion of buried pipeline
If you provide good information on this site, you will generally get good responses. However the info to date is very low.
Please provide:
length of pipe: - is it 48m in total or longer??
type of coating - type, thickness and age of coating
sand electrical resistance (water present or not)
Any salt water?
Some sort of sacrificial anode system might work, but without this sort of data no one stands a chance of getting it right.
