Abstract: A pin and box of a threaded connection are provided with interference fit metal-to-metal seals on both sides of a reverse thread section. The pin nose and box nose respectively are received in undercuts in the box shoulder and nose shoulder. The pin nose and box nose engage the respective shoulders at the same time on make-up. The thread section has a low profile, and the pin and box are kept short to reduce bending stresses.

Abstract: A pigging ball valve with a housing and ball core supported for rotation within the housing. The ball core sits on a valve seat, which is supported by a seat carrier. The valve seat carrier has three distinct diameters that locate the seat in the housing and thus provides an anti-cocking feature. A seat insert has a pressure sealing surface and wiper lip on the outer diameter of the pressure sealing surface. An internal seat deflector ring is provided inside of the pressure sealing surface. The seat carrier is spring loaded.
