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.

Abstract: A heat exchanger includes a plurality of fins and a plurality of tubes passing a fluid therethrough, extending through the plurality of fins and radially expanded into an interference fit therewith. At least one tube of the plurality of tubes includes an outer diameter, an inner diameter, and a plurality of ridges extending from the inner diameter inwardly into an interior of the tube. A tube internal surface area per unit of length of the tube multiplied by the ratio of the outer diameter and tube wall thickness is equal to or greater than about 30.0.
