Abstract: A threaded tubular connection which includes a pin member and a mating box member. The pin member has pin threads with stab flanks and load flanks and thread crests and thread roots which are adapted to be made-up with a mating box member having a complimentary thread structure. The threads of the pin member are intentionally made asymmetric to those of the box.

Abstract: A system for blocking rotation between a first tubular (102) and a second tubular (104) includes a key (202) positioned within a recess (204) formed in the first tubular (102). The system also includes a retention fastener (206) arranged within an elongated aperture (210) extending through the key (202). The system further includes an installation fastener (208) moving the key (202) from a storage configuration when in a first position to an engaged configuration when in a second position. The system also includes teeth (214) arranged along a bottom portion of the key (202), proximate the second tubular (104), the teeth (214) engaging the second tubular (104) via rotation of the key (202) about the retention fastener (206) and blocking rotation of the first tubular (102) relative to the second tubular (104) in a first direction (702).

Abstract: A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; wherein the first pipe and the second pipe are made from a reinforced thermosetting resin (RTR), and a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe, wherein a thermoplastic material is disposed between an exterior of the first pipe and an interior of the coupler. A thermoplastic material is disposed between an exterior of the second pipe and the interior of the coupler. Upon application of induction heating to the coupler, the heat between the first pipe, the second pipe, and the coupler is sufficient to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler.

Abstract: A coupled pipe connection system may include a coupling with internal threads adapted for joining two pipe sections by threaded engagement of external pipe threads with the internal coupling threads. A torque ring may be disposed within the coupling and between the first pipe and the second pipe. The torque ring may an outer cylindrical surface, at least a portion of which may include a plurality of tapered threads engaged with and tapered to match a mid-length axial section / J-space of the inner threads of the coupling. Annular faces of the torque ring may be beveled inwardly or outwardly and adapted for mating engagement with corresponding beveled annular faces of the pipe ends. Torque rings of gradually decreasing axial lengths may be incrementally swapped out as the number of make-up cycles increases. Couplings having internal shoulders of gradually decreasing axial lengths may be used instead of torque rings.
