A tubing hanger assembly including an outer hanger body () lands on a load shoulder () of a tubing head. Additionally, an inner hanger body () having at least one inner hanger groove () moves vertically up and down with respect to the outer hanger body and engages at least one downhole device. A first latch ring () expands into a groove () of the tubing head to lock the outer hanger body in position and a sleeve () with a plurality of grooves () is disposed between the outer hanger body and the inner hanger body of the tubing hanger assembly. Furthermore, a second latch ring (), disposed between the sleeve and the inner hanger body, expands into or collapse out of the at least one inner hanger groove () and the plurality of grooves () on the sleeve (), and the second latch ring () is a tension loading support for the inner hanger body.

Tension latch tubing hanger apparatus

An adjustable flow line may include an outer pipe body having a first flange, an inner pipe body partially disposed within the outer pipe body and axially translatable with respect to the outer pipe body, a metal seal positioned between an outer surface of inner pipe body and an inner surface of the outer pipe body, a sleeve positioned around the inner pipe body and outside of the outer pipe body, and a second flange positioned around the inner pipe body, wherein when connected to the first flange. The sleeve may be axially translatable with respect to the inner pipe body. The second flange may axially secure the sleeve with respect to the outer pipe body and cause the sleeve to energize the metal seal.

Adjustable frac flow line

A method for sealing a wellhead assembly having a first outer tubular member, a second outer tubular member mounted on the first outer tubular member and an inner tubular member landed in the first outer tubular member. The method includes: providing a packoff assembly having a lower packoff which is releasably connected to an upper packoff releasably connecting an installation tool to the upper packoff; positioning the lower packoff between the inner tubular member and the first outer tubular member and the upper packoff between the inner tubular member and the second outer tubular member; locking the lower packoff to the first outer tubular member; disconnecting the installation tool from the upper packoff; removing the second outer tubular member from the first outer tubular member; removing the upper packoff from the lower packoff; and mounting a third outer tubular member on the first outer tubular member.

In one aspect, this disclosure relates to a seat seal assembly for a valve. In another aspect, this disclosure relates to a gate valve or a ball valve including the seat seal assembly. In another aspect, this disclosure relates to a method of manufacturing a valve including the disclosed seat seal assembly.

Dual face-type seat seal arrangement for valve applications

A packoff assembly for sealing between an inner tubular member and an outer tubular member has a lower packoff which is configured to seal between the inner and outer tubular members, an upper packoff which is configured to seal between the inner and outer tubular members above the lower packoff, the upper packoff being releasably connected to the lower packoff and, when connected to the lower packoff, being axially movable relative to the lower packoff between a first position and a second position, a latch ring which is supported on the lower packoff, the latch ring being radially expandable into a corresponding locking groove in the outer tubular member, and a locking mandrel which is operably engaged by the upper packoff such that upon axial movement of the upper packoff from the first position to the second position, the locking mandrel expands the latch ring into the locking groove to thereby lock the upper and lower packoffs in position between the inner and outer tubular members. With the lower packoff locked in position between the inner and outer tubular members, the upper packoff can be selectively removed from the packoff assembly by disconnecting the locking mandrel from the upper packoff and disconnecting the upper packoff from the lower packoff.
