Abstract
A heat transfer system having a heat transfer fluid circulation loop of a first fluid is disclosed. A conduit is disposed in the fluid circulation loop with an inner surface in contact with the first fluid at a first pressure. An outer surface of the first conduit is in contact with a second fluid at a second pressure that is 69 kPa to 13771 kPa (10 psi to 2000 psi) higher than the first pressure. The conduit also includes a polyurea coating on its outer surface.
