The ends of fire tubes are flared and beaded primarily to aid in the flow of flue gases. When fire tubes are designed with a flared and beaded end, it facilitates a smoother transition for the exhaust gases exiting the tube. This design minimizes turbulence and resistance as the flue gases transition from the tube to the combustion chamber or exhaust stack. The improved flow characteristics help ensure that gases move more freely, enhancing the efficiency of heat transfer and overall performance of the boiler system.

Furthermore, while other options may have their own significance, they do not accurately address the primary function of the flaring and beading in relation to gas flow. For example, the design is not primarily focused on aiding in removal or specifically targeting expansion and contraction, although those factors may play a role in the installation and operation of fire tubes. Insulation purposes are also not the primary concern of this particular feature.
