Featuring a simple clutch mechanism which is adjusted to disengage at a point set by the operator.
The machines, except the P-types, are operated by a simple roll throttle.
The machine range enables you to expand tubes from 1/2” up to 6” OD.
Among the many applications is expanding U-tubes inwelded joints on thick tube plates, whereby the tubes are expanded after welding.
Automatic axial movement of the expander housing during expansion, ensures that tube elongation developed during this operation, is on the rear side of the tube plate.
Automatic overlapping of the rolling in stages.
For tubes 3/8” to 1 3/8” (9.5 mm to 34.9 mm) I.D. and
tube sheet thickness 2 1/2” to 27 1/2” (63.5 mm to 698.5 mm).
A special line of expanders to expand thin wall tubes, titanium, stainless steel and other high quality metals.
Available with special thrust collars, to eliminate the possibility of the tube being drawn up inside the thrust collar.
For tubes from 1/2” to 4 1/2” (12.7 mm to 114.3 mm) O.D..
Available with adjustable collar.
Expander mandrel is retained at rear to shorten mandrel length and to allow use near tube bends or I.D. fixed tubes.
For non ferrous or thin steel tubes so that another tube of the same diameter can be inserted and welded or soldered.
All tube sizes covered.
Available with adjustable collar.
Designed for expanding core seals, according to DIN 443,
in motor housings, cylinder heads and other caste parts.
Expander with 3/4” (19.05 mm) long rolls suitable for tube sheet thicknesses from 1/8” to 3/4” (3.175 mm to 19.05 mm).
Expander with 1 1/4” (31.75 mm) long rolls suitable for tube sheet thicknesses from 1/2” to 1 1/4” (12.70 mm to 31.75 mm)
