A short length of pipe used to connect two joints of casing or tubing. A casing or tubing coupling has internal threads (female threadform) machined to match the external threads (male threadform) of the long joints of casing.
API Coupling for Tubing and Casing Pipe - Permanent SteelThe casing pipe coupling is a kind of oilfield drilling tool, which is mainly used for the connection of the oil pipe, and mainly solves the problem that the existing coupling easily generates fatigue fracture due to stress concentration. The tubing coupling structure is:the tubing end is connected to the inner wall of the coupling by a taper thread, and the end of the coupling body and the

OIL & GAS CASING DESIGN - CASING CONNECTIONS - Jan 16, 2018 · The API Short Thread and Coupling (STC) and API Long Thread and Coupling (LTC) are used in pipe sizes of 4-1/2, 7 and 9-5/8. Figure 4 shows the LTC design. The STC design is the same except that the coupling and the threaded pins are shorter.
Premium connections ::ArcelorMittal Jubail. Saudi ArabiaConnection incorporates the most advanced casing and tubing technology and has been designed for the most challenging combination of environments and well conditions. Metal-to-Metal Seal Reverse ball & socket seal provides outstanding gas tight seal
May 11, 2020 · The length of premium connection coupling is longer than that of API coupling. In the middle of the coupling, the anti-over-torque step is mainly added to avoid over-torque. The inner diameter of the coupling is designed in parallel with the inner wall of the pipe to reduce the turbulence of gas or liquid in the pipe. Most premium connections of casing pipe are designed to increase their sealing surface on the basis of trapezoidal threads to achieve multiple sealing
Tubing and Casing Connections - DrillingForGasConnection types. For low pressure wells API 8RD thread connections have been the standard in the tubing strings. Non upset has proved more effective than upset (EUE) 8 RD tubing. Connections provided with metal-to-metal seals are commonly referred to as Premium connections.
