"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.

For tube expanding it is desirable to roll the tube quickly as it prevents work hardening of the tube and less frictional heat is generated. The limiting factors in this balance of speed vs. power are voltage or pneumatic pressure. These either limit the speed or power being produced.
Tube rolling occurs when the tube rotates due to inadequate friction between the tube OD and the hole in the tube sheet. This can cause increased expansion times and decrease the efficiency of the operator. Increasing the friction between the tube and tube sheet and or collar the tube will not rotate within the tube sheet. Increasing the friction can be done using several different methods:
Learn how to quickly change out roll sets to avoid drops in productivity.
In order to obtain the best results and improve tool life, proper lubrication is necessary. There are many different types of lubricants designed to suit specific applications and operator preferences.
