This component is a water accumulating and heating vessel inside the water heater. It is made from stainless steel sheet metal, which is rolled into cylindrical shape to make it a container.

Two ports are used for the inlet and outlet of water from the vessel. The ports are welded to top cap of the cylindrical vessel using TIG fusion welding application. The ports are welded using our port welding SPM on specially designed fixtures to maintain concentricity.
