When it comes to selecting a tube plug, there are a variety of options and factors to consider: application, material, and the ID of the tube. The three main types of tube plugs offered are one-piece, two-piece, and mechanical.
Choosing the right expander to suit your needs.
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.

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.
While tube leaks can occur for numerous reasons, one of the most common causes is the formation of holes. Holes can form within a tube as a result of deposit build-up, corrosion, improper cleaning heads being used, and more.
MB Engineering Services is an engineering services company that repairs heat exchangers for the offshore oil and gas industry. When exchangers are shut down, it is MB’s job to carry out the necessary repair work to get the heat exchanger back online as soon as possible.
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.
