tube lube - engineered to lubricate just where its needed.
Tube Lube stays where it is put and does not get in between the tube and the tube sheet. It's a lubricant which has been engineered to keep tube expanders from premature wear and keep them as cool as possible while under the duress of expansion.
The required rolling of tubes
using tube expanders is severe on
the tube expander itself. So, when
rolling tube, care is required in
the form of cleanliness, and the
cooling of the expander from the
friction to achieve a trouble free
and economical life.
Tube Slip has the Answer.
Inspect the inside and outside of the tube and remove all foreign objects and rust. Mill scale should also be removed from the tube especially from the inside of the tube as it can cause galling of the rolls and mandrel. This is when the rolls and mandrel pick up this foreign matter and be a factor in the breaking down of the tool taking it out of tolerance. Wire brushing the inside and outside of the tube will achieve a satisfactory surface.
Once the tube ends have been
prepped the tube expander should be
soaked in a commercial solvent to
remove and oils/anti rust, dirt and
grease. Once clean dry with a clean
cloth and apply a small amount of
Tube Slip to the rollers and work
this into the cage.
Now put a small amount inside each tube to be rolled, this also indicates which tubes need to be rolled and which is completed. Tube Lube is a paste which will stay in the tube not like an oil which could run down the tube sheet and get between the tube and the tube sheet where the seal is to be produced.
**BE AWARE OIL OR ANY LUBRICANT MUST NOT ENTER BETWEEN THE OUTSIDE OF THE TUBE AND THE TUBE SHEET AS THIS WOULD JEPARDIZE ACHIEVING A GAS TIGHT SEAL**
