• XLC-S Connectors

    Description

    XLC-S is XL Systems' second generation integral connector with pin and box threads machined directly into the pipe wall. This design produces an ideal connector geometry: a true flush inside diameter (ID) and flush outside diameter (OD).

    Featuring a wedge threadform with enhanced strength and fatigue performance, XLC-S is ideally suited for conductors and other applications where both structural integrity and special clearance is critical. XLC-S connectors have an external metal-to-metal seawater exclusion seal which prevents corrosion in the threads.

    XLC-S connectors make up in approximately three turns, the majority of which are low-torque spin-up until the wedge thread surfaces engage. Make-up torques are comparatively low and range from 30,000 to 60,000 ft-lbs depending on size. XLC-S connectors are suitable for makeup with either power tongs or manual tongs.

    XLC-S connectors have excellent field service history in a wide variety of offshore conductor applications since the late 1980's. XL Systems has completed extensive physical testing of XLC-S connectors, including full-scale fatigue testing and pile driving testing. XLC-S connectors are manufactured in 20-inch and larger diameters.
