Tube Expanders for Retubing Boilers and Heat Exchangers
Tubing Expander - Definition.
Powermaster Industrial Supplies provides quality tools worldwide when using tube expanders for retubing. A tube expander is a precision instrument used to widen the ends of tubes within a tube sheet. It comprises a Mandrel, Rolls, and a Cage. The mandrel, when rotated, is pulled into the cage due to the rollers’ angle. This action forces the rollers outward into the tube’s ID, causing the tube’s exterior to form a seal with the tube sheet. Consequently, the tube wall thickness is reduced to a predetermined percentage, which varies based on the tube’s size and material.
Tube Expanders and Internal Tube Cutters in our Tube Tools Range
Within our product line, we supply three different types of tube cutters in our tube tools range. Here we are highlighting our Internal Tube Cutter, the PR68 Series. These reliable, hard-working industrial internal cutters get the task completed. Cutting tubes and pipe up to 16 inches in depth.
Internal tube cutters, supplied to cut tubes from 1.2″ OD up to 4.1/2″ OD. Driven using either electric or pneumatic drives. The drive connection is via the 1/2″ male square. To aid with connection, accessories are available in the tube rolling accessories section.
Therefore these removal tools and many more can be found in the Tube Removal Link above.

Tube Tools and Retubing Procedures
On our retubing webpage, we aim to provide information on the retubing of heat exchangers and boilers. Therefore this information is based on our experience within the industry. No two heat exchangers or boilers will go the same way. So sometimes 85% of your labour time will be spent removing the old tubes. Tube tools for retubing can also be accessed on our sister site which specializes in boiler tube tools, boiler tube removal tools and boiler tube cleaning tools boilertubeexpanders.com Links above in the main menu.
A good place to start
Major Causes of Tube Leaks
Tube leakage causes are due to under-rolling and over-rolling. Likewise incorrect tube sheet preparation and differential thermal expansion. Improper expansion can pose difficulties for both the manufacturer and the repair serviceman.
Under-Rolling
Under rolling is inadequate tube expansion. The complete filling of the tube sheet hole is necessary for the proper amount of wall reduction. It is better to under-roll than to over-roll.
Over-Rolling
Over-rolling exceeds the required expansion of the tube’s inner diameter. This percentage of wall reduction is not necessary for the ultimate tube joint. Over-rolling can do considerable damage to a vessel. It will decrease the dimensions of the ligament between tubes and weaken this bridge. Once weakened, this causes a reaction in all ligaments surrounding that weak ligament. If we decrease the strength of the ligament the tube next to the rolled tube will leak.
Over-rolling also distorts tube sheets or drums thus forming oval holes. It will also cause diametrical expansion which is the increase of the tube sheet or drum. Over-rolling may cause a tube sheet to bow or warp. To correct this. Place stay rods in the vessel and position the tube sheets back to their original position.
