Retubing a vessel can be very extremely difficult depending on the type of vessel, how long the tube has been in service, and how efficient the initial expansion was. From support sheet bending to broken tubes, there are many issues that an operator can face during the removal process. Here are some tips & tricks you can use to overcome these common tube removal problems.
To pull tubes using a tube puller and spears, one of the first steps is to “set” the spear in the tube. This process is done by threading the spear into the tube ID with an impact wrench or by hand.
Tube pullers grip and pull the tube out from the tube sheet. There are a variety of tube removal tools available and each one has a specific use. Review the quick guide below to make sure you select the right tool for the job.
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.
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.

The factors affecting a Tube Bundle Cutter’s performance are: bandsaw blade selection, blade tooth pitch, cross-sectional area of the bundle, blade speed and feed.
"We pulled 10 times as many tubes with Elliott's spears, eliminating wasted labor and increasing our production."
"AREVA expects to double the tube removal speed by using the Elliott Cyclgrip tool. Since this tool only requires two people, AREVA can use other personnel more effectively."
Elliott's One-Rev deploys more advanced engineering principles with over 12 key differences that result in a superior product. The One-Rev cutter blade is designed to withstand even the toughest of materials.
