Hydraulic System for Tack Expanding

This new hydraulic manual expanding system is an easy-to-operate tool specifically designed for enlarging tube ends to produce the slight contact required between the tube OD and the tube sheet hole prior to welding the joints. It can also be used to calibrate tube ends or to fix the tube inthe tube sheet hole prior to conventional mechanical rolling.
Special Features • Simple operation and adjustment
• Centering of the tube in the tube sheet hole.
• Easily changed to another tube size
• Minimum stress on the material
• No stressing of the tube surface
• Total circumference expanded in the required area.
• Expanding tools from 8 mm – 100 mm availiable
