3 Roll Condenser Exchangers - 1/4 (6.4) - 3/8 (9.5), 1/4 (6.4) to 3 1/2 (89mm) tubesheet The Series 41-A and 44-A expanders were primarily designed for very small tubes as generally found on lubricating oil coolers and heat exchangers of simiilar characteristics. It features an adjustable ball bearing collar to meet the requirements of various thicknesses of tube sheets. In the 1/4" size the collar is flush. In the 3/8" size the collar has a 1/16" recess. The mandrel is retained in assembly by a Wilson exclusive design, incorporating a knurled nut located at the back end of the threaded cage shank. All parts are of alloy steel, properly heat treated. Mandrel and rolls are precision ground after hardening.

Pipe Sizing Expanders True Up or Bring Pipe or Tube Ends to Round Wilson Pipe Sizing Expanders bring pipe or tube ends to a precise diameter to prepare them for soldering or brazing into sil-braz and similiar pipe fittings. Very close manufacturing tolerances ensure that rolls expand in a parallel manner.

Linsen Flaring Expander The Linsen Expanders are power-driven tools designed for making
tubing connections without fittings. It enlarges end of tube,
leaving .015” clearance for slip fit, so that another
tube can be inserted and soldered like a sweat fitting. It is
excellent for short bends, U-turns, copper, brass, aluminum,
or thin steel tubing. |

 |
Expander Lube - Type B Wilson Expander Lube is a water-soluble lubricant especially
compounded for use with tube expanders. When rolling large or
small, ferrous or non-ferrous tubes, use Wilson Expander Lube
for smoother rolling and longer expander life. For clean tube
ends after rolling, simply wash with water. Wilson Type B |
