Bored, cased pipe cathodic protection

[jbraud]

I have a situation where an 8" insulated, cased line will be installed via boring and jacking +/- 600 feet. The pipe will only be accessible where it exits the ground on each end. Can someone recommend which method to look at for cathodic protection?

In general insulated pipes do not get any protection from cathodic protection. who is telling you that it actually needs CP?

What type of insulation?

What do you mean by "cased?"

got a cross section you can share?

If this is inserted into a casing pipe which is bored and jacked what are the plans for the annulus - leave it open or grout it?

The client wants an 8" steam line installed under a right-of-way from one facility to another. I'm not even sure if it is feasible or not yet and just exploring all aspects of a buried line. The line is proposed to be insulated and cased in at least a 12" casing. I was thinking more of the casing needing protection.

I am not sure of the insulation type that will be proposed yet. 500# superheated steam.
