Type C Anti-Rotation Anchor

Type C Anti-Rotation Anchor The Type C Anti-Rotation Anchor is used to prevent tubing back off inprogressive cavity pump applications. Run as an integral part of the tubing string, the anchor automatically sets when tubing torque is present to prevent rotation of the tubing string.

Key features
  • Compact design allows for a large gas by-pass area
  • Rocker drag slip for reliable setting and releasing
  • No set screws
  • One-piece mandrel Operation The Type C Anti-Rotation Anchor is simply run to depth with the pump. When torque is applied to the tubing, the wickers on the rocker drag slip engage the To release, rotate the tubing a small amount to the left to ensure the slips are Tubing Anchors Casing Ancho r Torqu e Tested Body I.D.

Type C HD Tubing Anchor Catcher

Type C Heavy-Duty Tubing Anchor Catcher The Type C Heavy-Duty Tubing Anchor Catcher provides a reliable method of anchoring the tubing in rod pumped wells. The Type C utilizes drag blocks with corrosion resistant springs and heavy-duty slips to ensure long life and to minimize repair costs. The Type C is available in either the more common left-hand set/right-hand release version or it is available in a right-hand set/left-hand release version for use in situations where the possibility of right-hand torque in the tubing string is a problem. All Type C anchors come with an adjustable (in 5,000 lb. increments) secondary shear release.

Key features
  • Corrosion resistant shear screws
  • Secondary shear system is easily adjusted in the field without disassembling the tool
  • Reliable slip retraction system to insure safe retrieval
  • position
  • The wear resistant drag blocks with Inconel springs combined with heavy-duty one-piece slips reduce repair costs
