Suitable for the manufacturing and retubing of fire-tube boilers, the combination beading tube expander completes the expansion of the boiler tube into the tubesheet and the beading of the tube end in a single pass. This significantly enhances the mechanical stability of the tube ends, ensuring a long-lasting, high-strength, and reliable fixation of the tubes within the tubesheet. It effectively eliminates gaps, significantly reducing the risks of steam and flue gas leakage. Ultimately, this multi-purpose tool shortens processing time, improves production efficiency, lowers labor costs, and reduces equipment investment.
