Tubing coupling used to connect pipelines API Coupling with threads
on both ends
Normally tubing coupling OD maximum is 4 1/2”, as the tubing pipe
is applied for the drilling activities (Inside the tubing is the
sucker rod to drill/pump the oil), couplings type is more various
and rigorous than casing, mostly used is thicken type upset
coupling (Internal upset and external upset), for short is EUE coupling, it is the most favorable in tubing connections. Tubing with EU
end (EUE) coupling connection also called UPTBG. Because of the end
of the tubing is thickened (upset), the connecting stress is better
than buttress coupling.Buttress coupling another type used for
tubing connections, it has the same thickness of the pipe body,
called NU end (NUE)tubing or TBG.
Tubing coupling
Features
The oil tubing coupling can solve the problem of fatigue fracture
in the existing coupling due to stress concentration. Oil tubing
end is connected to the inside wall of the coupling in a tapered
thread. The coupling body end and oil tubing are connected with
same thread pitch flat thread. The coupling is not easy to produce
fatigue fracture, and has good connection effect. It can prevent
the accident of oil well pipe string break effectively.
