XCalibur delivers proven gas sealing performance

Unique offering represents the most advanced threaded and coupled connector on the market

Nov 16, 2021

XCalibur is the newest addition to the XL Systems product line of large diameter conductor and casing, delivering robust performance features for challenging onshore and offshore applications facing possible shallow gas exposure. It is a large diameter threaded and coupled connection featuring a liquid and gas-tight metal seal with proven gas sealing performance.

The operationally friendly XCalibur is an economical alternative to weld-on connectors that delivers high strength options for non-weldable pipe grades, saving the time and cost of welding a box onto the ends of pipe.

The multi-purpose connection is available in 16-inch to 24-inch sizes and suitable for a variety of energy applications, including onshore, offshore, geothermal, surface casing and liner strings with gas sealing requirements, as well as deviated & gas storage wells.

The user-friendly product requires no special tools for running, only the standard handling tools common to any rig. In addition, NOV will offer a licensee repair network to ensure the highest quality product support.

“We set ourselves a challenge to design a more economical, technically advanced solution for our customers,” said XL Systems Regional Account Manager, Phil Gwyn. “This unique offering represents the most advanced connector on the market today.”

XCalibur’s metal-to-metal gas tight seal is verified to API 5C5:2017 CAL I protocol, and the product is rated to 100% pipe body performance for load and pressure.

Product features include:

  • Double start threads: Deep stabbing design for quick and reliable make-up, eliminating cross-threading.
  • Dope/stress groove: Eliminates excessive dope pressure, delivering consistent makeup, reliable seal engagement, and maximizing load distribution.
  • Integral threaded pin: Features a counter-bored pin nose, creating uniform seal contact pressure for reliable sealing performance.
  • Engineered threadform: Maintains engagement under extreme loading and interference that builds torque energy over half a revolution, preventing unintended connector back-off.
  • Metal-to-metal seal: Internal gas tight primary pressure seal designed to consistently perform under high combined loads.
  • Forged coupling: Uniform geometry and mechanical properties
