Tube Expansion System ( Electric Drive With DigitalTorque Controller )
Tube Expansion System
 

...regulates amount
of expansion or
degree of tightness
of a tube joint

Tube Expansion System The Digital Torque Control Unit is constructed from most modern components, to provide an accurate means of controlling the amount of current supplied to the driving unit so that the torque can be regulated.
The Digital Torque Control Unit will automatically switch off the drive unit as soon as the drive current reaches a preset value of expansion or torque has been attained. The digital readout allows precise setting to the exact torque required.

The Digital Torque Control Unit is built to operate four types of driving units PD-0, PD-1, PD-2 & PD -3 The drive is a conventional electric drill type machine. The characteristic of the unit is such that the current drawn by the motor increases as the load is applied and by the accurate measurement of this current the effort produced is determined and also the degree of tube expansion, when the preset torque is reached.
Tube Expansion System Features :
  • Eliminates over rolled and under rolled tube joints

  • Increases production - reduces costs

  • Release skilled employees for more precise work

  • Assures uniformly rolled tube joints

  • Reduce need for constant inspection
