4-Roll Boiler Tube Expander, Self-Feeding, Flaring (Series 116)
SKU: N/A
Wilson’s Series 116 Expanders offer four expanding rolls and two flare rolls and simultaneously flare and roll an unusually fine surface with a minimum amount of indentation by the flare rolls. This flaring operation works ideally for HRT and other fire tube boilers where final beading of tube ends is the practice. This Wilson Expander’s self-retained rolls make it well-suited for use with reverse taper mandrels for far end tube expanding.
