tube materials for geothermal wells
tube materials for geothermal wells
(OP)
Hi,
I am looking into materials for geothermal tubes applications and I have a few questions:
1. What are the materials generally used?
2. Are there applications out there for higher corrosion resistance materials (e.g. Ta, Mo, Nb, Ti, others)?
3. What is the main failure mode of these tubes and what causes it?
I know it is a lot to ask and I greatly appreciate your help.
All the best,
Kristiaan

RE: tube materials for geothermal wells
In the hottest and most corrosive wells you will see Fe/Cr/Ni/Mo alloys (825) being used.
There are reports from Geothermal Resources Council (GRC) that describe what people have used.

Thank you for your reply.
I found a very good article you posted somewhere else about this.
Best regards,

Good point! I was interested in tubes for geotermal power applications.
I am interested in the feasibility to promote Ta tubing (or similar) in applications where corrosion is a significant problem.
Thank you for your reply.
