Protective Coatings for Hot Water Vessels
Protective Coatings for Hot Water Vessels
(OP)
Can anyone recommend an air-dryed coating system for painting the interior of carbon steel pressure vessels for hot water service at 160 - 220 degrees F. Our normal paint supplier (Tnemec) doesn't have a product that can reach the 220 deg. limit. We have an oven, but would prefer not to use it if we don't have to. It must be a spray on coating (airless or conventional).

What is the end use of the hot water there might be other possibilities?

To sjones: the working pressure is 50 psi maximum.
Carboline has expressed initial concern about the potential for coating/surface separation due to "cold wall effect" because these vessels will not be insulated on the exteriors.
We had a problem with vessel lining separation using a PVC lining known as Miccrosol, several years ago. The manufacturer of the system, Michigan Chrome, thought that it might be caused by cold wall effect because the vessels weren't insulated. But, now I wonder if it could be from decompression or both.
Has anyone had any similar experiences?
