Floating Head Type Heat Exchanger

The floating head is formed by the floating tube sheet, spherical head and a split backing ring the entire assembly bolted together. The purpose is returning the fluid circulating inside the tubes to the stationary head. The fabrication of floating heads is complex, requires many hours of machining and strict quality controls. Nevertheless, leaks can occur due to the large number of jacketed gaskets present.   A floating head exchanger is suitable for the rigorous duties associated with high temperatures and pressures.
