High temperature pipe tape
High temperature pipe tape
(OP)
Does anyone know of a pipe coating system for steel pipe under insulation? We looking at a carbon steel line operating at 98C (but design temperature is 180C). This duty has seen surface corrosion under the insulation due to water ingress. The water forms a convection cell under the cladding and condenses on the pipe surface.
We have a painting option but are there simpler tape systems?

180C is rather high for any sort of tape or PE/ PP / epoxy system and you might be into something like Thermally Sprayed Aluminium (TSA). Not cheap but very good.

Also: If you get a response it's polite to respond to it.

This isn't as good as TSA, but costs less.
The Al will act as a sacrificial anode and help delay pipe corrosion.
Your temp is about the worst, hot enough to dry the pipe sometimes, but not enough to keep it dry.
