March 6, 2008

I am working as a constrcution personnel with a company in Saudi arabia and we face a problem that the gas turbine cooling water line have been flushed with water and even after several flush we find the water more dirty inside, is there any method to remove the rustiness and dirt from the pipe ?

You can use IceBlast, a non abrasive blasting technology, to remove the rustiness and dirt from the pipe. You can also use IceBlast to clean the turbine.

Citric acid is a good cleaner for rust. Protect the pipes after with som rust protection.

We also have good results using Iceblast on this kind of deposits. We have blasted heat exchanger pipes internally for example and it does not harm the base material. Of course, size and form might give trouble, but it is worth trying.
The residual water is the only thing left. Success!
