• XLF Connectors


    XLF is a high-strength integral connector with pin and box threads machined directly into the pipe wall. This process produces the ideal connector geometry of a flush inside diameter (ID) and flush outside diameter (OD).

    The XLF connector has an internal metal-to-metal pressure seal, making it an ideal choice for casing strings with pressure integrity as the primary design driver. XLF connectors are rated at 100% of pipe body strength in internal and external pressure.

    XLF 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 40,000 ft-lbs depending on size. XLF connectors are suitable for makeup with either power tongs or manual tongs.

    XLF is XL Systems' first generation wedge thread connector. It has an excellent field service history in a wide variety of onshore and offshore casing and conductor applications since 1986. XLF connectors are manufactured in 20-inch and larger diameters.
