Coiled Tubing Tower

  • Profile
  • Technical data
  • Media & Downloads

The Coiled Tubing Tower is designed for inserting a tube, rolled up on the ground as a coil, which is guided by the injector or by tools fitted at the front end of the tube into the bore hole. The tower consists of the base frame, onto which various intermediate segments are fitted in order to achieve variable heights, and the lift frame for holding the injector. The intermediate segments fitted on top of the base frame can be laterally displaced for changing the tools.

Components

  • Base frame - The outside support feet are hydraulically height adjustable and the inside support feet are height adjustable via trapezoidal spindles.
  • Base segment
  • Intermediate segment, 3,000 mm height
  • Intermediate segment, 2,500 mm height
  • Intermediate segment, 2,000 mm height
  • Intermediate segment, 1,500 mm height
  • Lift frame for injector, height adjustable up to 700 mm

Operating elements

  • Hydraulic control panel - base frame | The individual adjustment of the four lift cylinders and the joint actuation of the two horizontal displacement cylinders are performed from the control panel.
  • Hydraulic control panel – lift frame | The joint/synchronous actuation of the four lift cylinders is performed from the control panel.
