Abstract
A jacketed vessel for temperature control of contents within the vessel is provided. The vessel has a shell and an external jacket through which heating or cooling fluid is circulated. The jacket is formed by a length of conduit arranged in a spiral orientation around the vessel shell. The conduit has a center portion having a concave inner surface and has opposing side portions having convex inner surfaces. Edge sections of each side portion are welded to the exterior surface of the shell to form the jacket. Edge sections of adjacent arcs of conduit may be simultaneously welded to the shell in a single weld pass. The shape of the conduit provides improved heat transfer and pressure drop characteristics, as well as improvements in the vessel manufacturing process.
