i believe tube belling is:
this is the way in which the tubes in a boiler are secured at the ends to prevent the ends from burning off or leaking.
in firetube boilers, the tube ends are 'beaded' to prevent them from burning off or weakening at the ends.
in water tube boilers, the ends of tubes are 'flared' so that there will be no leakage at the end of the tubes.
(im sure about how the types of belling on the tubes, but as for the reasons i posted, im only about 80% sure that the water tubes are "flared" to deal with leakage. so correct me if im wrong.)
