Extended couplings for oil field tubing
Tubing coupling is a type of drilling tool used in oil fields, mainly for connecting tubing.
Tubing couplings are a type of drilling tool used in oil fields, mainly for connecting tubing and solving the problem of fatigue and fracture caused by stress concentration in existing couplings.
The structure of the oil pipe coupling is:
The end of the oil pipe is connected to the inner wall of the coupling body with a conical thread, and the end of the coupling body is connected to the oil pipe with a flat thread of the same thread and pitch. It has the characteristic of relieving stress concentration at the root of the external thread of a single cone thread connected oil pipe, making it less prone to fatigue fracture and achieving good connection effect. Effectively prevent the occurrence of oil well string breakage accidents.
Couplings are divided into tubing couplings and casing couplings.
The main characteristics of petroleum couplings include corrosion resistance, high temperature resistance, and wear resistance. Oil couplings are commonly used in oil extraction environments such as oil wells and geothermal wells, and have high corrosion resistance and high temperature resistance, which can adapt to harsh working environments.
