The Linsen Expanders are power-driven tools designed for making tubing connections without fittings. It enlarges the end of a tube, leaving .015-inch 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.

Wilson Long-Reach Expanders expand tubes at points far back from the tubesheet, such as the point at which it passes through a baffle sheet.

Tube Outer Diameter: 58 to 412-Inch, 8 to 22 Gauge
Roll length: 1 12 or 2 14-Inch and Relieved
Extended reach: 6, 12, 18, 24, 30, 36, or 60-Inch

Easy to use
Only hand wrenches for insertion and withdrawal
Overall length held short to operate in tight places

Wilson Captive Mandrel Tube Expanders enable tubes to be rolled where mandrel travel is limited because of restrictions in the tube Inner Diameter or when the tube bend is very close to the rolling area.

For 38- to 2 12-Inch Outer Diameter tubes
To order a captive mandrel expander, provide us with the details of your specific application (tube Outer Diameter and Gauge, tubesheet thickness, and maximum mandrel travel)

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.

Features:

For .435- to 12-Inch Inner Diameter pipe and tubes
When ordering, specify tube Outer Diameter and Inner Diameter, tube metal and approximate depth of rolling.

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 similar characteristics. It features an adjustable ball bearing collar to meet the requirements of various thicknesses of tubesheets. The assembly comes complete with mandrel, rolls, cage, and collar with a flush (for 14-inch size) or 116 recess (for 38-inch size).

NOTE: On selection of expanders, wall thickness of tubes run either nominally or minimum wall.
