Product Description

Spline Expansion Joint is designed for packers in well completion to compensate for tubing movement during treating and injecting operations and where rotation through the tool is required. The design allows torque to be applied through the Spline Expansion Joint at any position.

Features:

  • Rotationally locked at all times for transmitting torque when required.
  • Multi-spline design for high torque load.
  • Maximized tension carrying capability.
  • ID compatible with tubing ID.
  • Tool can be pinned at one foot spacing from closed to fully stroked position.
  • Shear value can be adjusted by varying the number of shear screws.

Torsional Rating of Spline Expansion Joint:

  • 10,000 psi for Standard Service application at 110,000 psi material yield.
  • 10,000 psi for Sour Service application at 80,000 psi material yield.

Temperature Rating:

  • 300 degree F for Standard Nitrile Chevron at 0% H2S
  • 200 degree F for 70 Hard Bonded Nitrile at 0% H2S
  • 300 degree F for 90 Hard Bonded Nitrile at 0% H2S
  • 275 degree F for 95 Hard Viton at 5% H2S
  • 300 degree F for V-Ryte at 15% H2S
  • 450 degree F for V-Ryte at 5% H2S
  • 300 degree F for A –Ryte at 20% H2S
  • 450 degree F for A-Ryte at 5% H2S

    • Tensile Rating is compatible with tubing.
