WebJun 1, 2024 · Abstract. Strength calculation for tubesheets in floating-head heat exchangers (FHXs) in current standards is based on analytical theory which assumes that the two tubesheets are symmetrical with same thickness, same material. This assumption results in a design that is not optimized for the requirement of the FHXs. In this paper, a … Web2 days ago · The floating head exchanger is, therefore, the best heat exchanger in terms of efficiency and maintenance, but naturally comes at a higher cost.
