A tube bending machine with rotary arms carrying a bending moment roller and a bending fulcrum roller has arm shafts mounted for axial movement. The arms are rotated for the tube bending action, whereby the bend so made in the tube lies in a predetermined non-planar arc. The arm shafts are turned by a pinion engaged by a rack and are moved axially by suitable pins engaged in cam slots with the rack and the cam slots all being moved simultaneously. In order to retain the tube in proper location or position during the trusts of non-planar arc bending there may be included more than one roller.

Tube bending machine

Flow restricting devices are provided for individual tubes connected into bores in a tube bank and are each formed with a convoluted passage of restricted cross-sectional area and extended length to produce a required flow restriction.

Tube banks

A steam and water drum internal arrangement which provides free access to the drum inner wall and facilitates the removal of the steam and water separators from within the drum by mounting the separators on a duct which extends centrally of the drum and communicates with extension conduits to receive a steam and water mixture from the steam generating tubes.
