1200 Series Tube Expanders

1200 series tube expander

The 1200 Series tube expanders are used on heat exchangers with thick tube sheets. The expanders come in 4 standard reaches with either 1.1/2″ or 2.1/4″ length of roller. These tools cover from 1.1/2″ reach to 12.3/4″. Even if you are rolling with the 1.1/2″ or the 2.1/4″ rollers you can use the reach to step roll into thick tube sheets. Also, the length of reach allows passing through headers to get to the tube sheet.

Uses of the 1200 Series Tube Expanders:

  • Most popular tube expander worldwide for heat exchangers and condensers. 
  • Can be used for step rolling thick tube sheets. 
  • Ideal for rolling through water walls etc.

We work to high tolerances for all machining of expanders and associated equipment. This allows accurate expansion to achieve perfect sealed joints in tube sheets. Using the best tool steel and cryogenic processes for hardening and conditioning. Giving our tooling the optimum performance in the harshest surroundings.

We assemble each expander while checking the quality of the manufacture. Every individual tool is laser-marked with our name, Powermaster Canada. Also, we mark with the tube OD, wall thickness and expansion range. Expanders are then oiled bagged and boxed for shipping. Therefore, with our quality control and machining excellence, we supply a quality tool.
