Condenser Tube Expanders

SERIES 41-C, 44-C, 47-C

3 Roll Condenser Expanders —
1/2 to 1 1/2-Inch Outer Diameter — (1 1/2-Inch (38.1mm) Roll Length C)

The Model 41-C, 44-C, and 47-C Expanders are suitable for expanding tubes in condensers and/or evaporators, heaters or coolers.

The long-reach 41-C, 44-C, and 47-C Expanders are particularly suitable for thick and multiple tubesheet applications where step rolling is practiced. They are unsurpassed for use on condensers and heat exchangers of oil refineries, chemical plants, atomic energy installations, and others.

A = 1/2 (12.7mm) to 1 1/2-Inch (38.1mm) Tube Outer Diameter

B = 9 (9.8mm) to 22 (.7mm) Gauge

C = 41-C - 1/2 (12.7mm) to 1 1/2-Inch (38.1mm) Tubesheet
       44-C - 1 1/4 (31.8mm) to 6-Inch (152.4mm) Tubesheet
       47-C - 1 1/4 (31.8mm) to 12-Inch (304.8mm) Tubesheet

 

47-C and 47-D Expanders are similar in design to the Models 41 and 44 previously described.
However, the threaded shanks are extra-long and suitable for the unusual conditions of
extra-thick or widely spaced multiple tubesheets.

Expander Lube - Type B
Series 114 Expanders
Wilson Expander Lube is a water-soluble lubricant especially compounded for use with tube expanders. When rolling large or small, ferrous or nonferrous tubes, use Wilson Expander Lube for smoother rolling and longer expander life. For clean tube ends after rolling, simply wash with water. Wilson Expander Lube is used straight from the can without dilution. View service manual SM-34.
