114 Series Tube Expanders

114 Series Tube Expander
114 series tube expanders is one of the most common boiler expanders. Used for flaring tubes with a 40-degree flare in a compact design. Self-retaining rollers held in place using an inner sleeve. Thus allowing the cage and rollers to be placed in the tube before inserting the mandrel. Therefore allowing easier insertion when limited access is available. Meanwhile, some manufacturers and service companies use a flaring expander before manual beading.
In summary, the general design of this expander incorporates overlapping rolls, accordingly this  eliminates ridging. Consisting of four straight rollers. This makes the gas-tight seal and an additional two rollers for flaring. Albeit a flaring expander, the 114 series is convertible to a straight rolling configuration.
