XLW is a unique hybrid connector with an integral pin thread and a weld-on box. The XLW connector features a flush inside diameter (ID) profile and an upset connector outside diameter (OD), which form an integral lift shoulder.
The XLW connector features wedge thread technology and an internal, metal-to-metal pressure seal and is rated to 100% of pipe body capacity in internal pressure, external pressure, tension, compression, and bending. XLW connectors are ideally suited for critical casing strings in which both pressure and structural strength are design drivers.
XLW connectors make up in approximately three turns, the majority of which are low-torque spin-up until the wedge thread surfaces engage. Wedge thread technology provides anti-rotation in open water without the need for installation of an additional locking device.
XLW connectors are suitable for makeup with either power tongs or manual tongs. Makeup torques are comparatively low and range from 30,000 to 60,000 ft-lb depending on size. XLW connectors are manufactured in 20- to 48-in. diameters.
