Tube Expanders
True parallel pin expansion — eliminating stress on welded tube joints.
Elliott's PX24 Series offers true parallel pin tube expansion, which can reduce the stress created on welded tube joints when compared to tapered rolling. Ideal for chillers, heat exchangers, feedwater heaters, and surface condensers.
- Tube Size: 0.750" – 1.000" (19.05 – 25.4mm) OD
- Roll Type: Parallel Pin Condenser Expander
- Application: Chillers, Heat Exchangers, Feedwater Heaters, Fin Fan Coolers, Surface Condensers
“Switched to the PX24 after cracking welds with tapered tools. Problem solved.”
