Single roll beading expanders simultaneously expand and bead the tube ends in firetube boiler applications. This tool accomplishes the creation of a pressure-tight tube-to-tube sheet joint, and a beaded tube end, by utilizing the natural feed force built into the expander to push the beading roll against the end of the tube while expansion is taking place.
Cleaning tubes increases energy efficiency. Every tubed vessel (ex: boilers, heat exchangers, condensers, chillers, etc.) requires the surface of the tubes to be clean and scale-free to function efficiently. If deposits or scale are present, the flow through the vessel and the efficiency of the vessel decreases.
Tube Expanding is the art of reducing a tube wall by compressing the O.D. of the tube against a fixed container, such as rolling tubes into tube sheets, drums, ferrules or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage.
"Elliott’s 24 Series Tube Expanders have incredible tool life. Elliott’s 24 Series is saving me over a thousand dollars per month."
When removing tubes from a vessel, one of the most difficult tasks can be removing tube stubs from the tube sheet. Depending upon how long the tube has been in the vessel, in addition to how efficient the initial expansion was, the removal process can be very difficult.
When installing heat exchanger tubes, it can be difficult to guide them through the support sheets or baffle holes. The best way to overcome this challenge is to use Elliott Tube Pilots.
In order to properly maintain your vessel, the right cleaning tools must be selected to clean the tubes. When trying to select a turbine cleaner and head, the abundance of options can seem overwhelming. However, when sizing turbine cleaners there are a few pieces of information that can help you select the ideal cleaner and head.
