Tailing Pipe MOC - What is used in Tar Sands?

[Guest102023]

As described - what alloys are used?

Service temperature is down to -40°F, with welding to flanges, etc. Charpy impact toughness is 25 ft-lb minimum. The main service concern is erosion corrosion.

I suspect that some form of chromium carbide overlay for carbon steel base pipe material would be among the more accepted options. Google "Indulay" and "Hard Wear" for starters. I am not sure what the limitations are with respect to pipe size, but I imagine you are looking at some pretty large lines.
