Thesuperheater tubes are arranged in pairs,the two tubes in each pair being con-nected at the back ends by cast steel re-turn bends. The ends of the superheatertubes are bent around horizontally to meetthe steam headers. This arrangement al-lows complete freedom for the expan-sion and contraction of the superheatertubes due to variations in temperatureand thus serves to prevent the leaking ofthe joints. The ends of the superheaterpipes are upset and machined to form aball which is ground into its seat in the 4-4-0 FOIi THE WESTERN OF HAVANA.
