Oily water sewer piping material
Oily water sewer piping material
(OP)
I am preparing a piping spec for a condensate treatment facilty. We have a UG oily water sewer which will be atmospheric and the temprature would raise up to 580F. The required service life is 20 years.
Can anyone help me with material selection? The given options are carbon steel, ductile cast iron, fiberglass and reinforced concrete, I am not sure whichone will be the best option.
Thanks in advance.

Correct me if I am wrong but but FRPs are not suitable for 580F, are not beenig recommended for temperatures more than 150-200F.

Based on your comment, can I assume for such temperature there will be no option but welded carbon steel piping? Even ductile iron will be out of options?
Thanks again.

Steel pipe will probably not survive for 20 years in this application. Condensate is corrosive. The pipe will also be attacked by the soils.
Some of stainless steel alloys will stand up to the fluid but will also be susceptible to exterior corrosion.
If the high temperature occurs only occasionally, the FRP may work. You might want to run the question by the supplier. The performance limits on the pipe are based on the combined affect of temperature and pressure, not just temperature.
You may also consider revising your process to eliminate the high temperature.

While the converse of this, i.e. water poured or sprayed onto hot oil, may not be quite as bad as I believe demonstrated by the "Mythbusters" at http://www.discovery.com/tv-shows/mythbusters/vide... , both certainly fall into the don't try this at home category, and I can't believe the Myth guys didn't vociferously mention the very much inadvisability of anyone trying the demo the other way around!

you must get smarter than the software you're using.
