The line will be an 8" header for vacuuming services in a power plant (flyash). We've used steel in the past but the are heavy and expensive to replace when they erode through. I was wanting to use a cheap plastic (PVC or CPVC). I don't think PVC will work temperature wise as the ash can sometimes be around 250-300F. Is there any other relatively inexpensive plastic pipe I can use that has a good thermal rating (like CPVC) but is better at resisting erosion??

I would suggest fiberglass- check out the source below for reference documentation of a high temperature/ wear resistant product.

You will absolutely be left to the unfortunate conclusion that you need to use steel. You can add abrasion resistant fittings (very expensive), tile, etc, but you are relegated to the age old problem of managing the wear properties of ash.
