Stamped Dimple Jacket Heat Transfer Surface

A dimple jacket is a machine formed sheet material that is welded to a second piece of material after forming, such as a tank heads or shells. Dimple jackets are also a versatile heat transfer surface primarily used for temperature and pressure extremes on the outside of tank heads and shells. The customizability of dimple jackets is one of the major benefits of this kind of heat transfer surface.

Would it help to have a fully-welded dimple jacket assembly show up at your door? We can provide fully-welded integral assemblies with tank heads, shells, and dimple jackets.
