High Temperature Water Resistant Coating for Steel Pipe

I am a consulting engineer in the process of developing a product for the management of hydronic heating and cooling systems in buildings and have experienced conflicting claims in my search for a coating needed by the product.

I need a recommendation for an electrically insulating coating for a new product under development which will have continuous exposure to chilled and/or heated water up to 230 degrees F. The substrates will typically be the interior surfaces of short lengths of steel pipe and fittings from 1" to 24" in diameter and used in heating and cooling systems in buildings. The coating should be expected to have a life expectancy under continuous exposure of at least 10 years. Factory application of the coating is preferable.

A Teflon coating is a good candidate to fit under those working conditions.
