Are stainless steel pipes also protected by CP Sytem???

RE: Stainless steel vs CP
Are there any CP standards for protecting SS?
RE: Stainless steel vs CP
Care should be taken however in selecting the CP system to be used, depending on the grade of stainless steel to be used, the soil conditions, and the life of the asset. Stainless steels can suffer from hydrogen embrittlement, so care must be taken to avoid over protection of the steel and the resultant Hydrogen evolution that occurs.
A competent corrosion engineer should be able to assist you.

This is one area where you need to hire a pro.

RE: Stainless steel vs CP
Would the passivation process of the stainless steel pipe buried underground when it is fully polarised?
Thank you for your comments. This is my first post.
RE: Stainless steel vs CP
1. Stainless steel is specified for the process side environment - not the "buried" side from a corrosion standpoint, hence, coated carbon steel cannot be used.
2. The problem with S.S. in buried service is that full polarization may not be achieved throughout the length of the burial without application of CP.
RE: Stainless steel vs CP
I'm sorry for the second question I asked. I made a mistake. Let me re-phrase it.
Would the passivation process of the stainless steel pipe (outer surface) be compromised, when it is buried underground and with application of CP (impressed / sacrificial)?
Thank you for your first reply.

Does that seem like an acceptable method to protect the tubing?
