Abstract
In a shell and tube type heat exchanger, flattened tubes (50) are inserted between each layer of tubes (36) in the tube bend region thereof. The flattened tubes are then pressurized, to expand them in the region below the tube bends (60), so that they lock the batwing support plates (41) into place, thus preventing them from vibrating and causing damage to the tubes in the first few rows of the tube bundle.
