AboutPipe Coupling

Normally the maximum OD of the pipeline connection is 4 1/2", as the pipeline pipe is applied for drilling work (inside the pipeline suction cup rod to drill / inject oil), the type of connections is more diverse and strict than the casing, mainly used thickened coupling of the detuned type (internal disorder and external disorder), for short-EUE coupling, it is most advantageous in pipe connections. EU End Pipe (EUE), also called UPTBG. Due to the fact that the end of the tube is thickened (detuned), the connecting voltage is better than the connection of the supports.

A different type of support coupling is used to connect the pipes, it has the same thickness of the pipe body, called the NU end (NUE) of the tube or TBG.

Features

The end of the oil pipe is connected to the inner wall of the coupling by tapered thread. The end of the coupling body and the oil tube are connected by a flat thread with the same thread pitch. The connection is not easy to produce fatigue failure and has a good connection effect.

AboutHousing Coupling

Shroud connection for inches larger than 4 1/2. Unlike pipe coupling, housing coupling usually does not need to be thickened (no parting), which means there is no detuned housing coupling, so it has the following types:

• BTC: Pole Connection

• LTC: Long termination coupling.

• STC: Short connecting support.

All three types have the same casing body thickness, just have different lengths.

The coupling of the oil casing is a necessary part used to connect the two casings. The manufacturing method of the coupling is the same as that of seamless pipes. The steel pipe ends with an internal thread to connect with the upper and lower casings.
