Tubing clamp is a key component for connecting tubing in oilfield drilling operations, and its design and function are centered on improving the reliability and safety of the connection, with the following specific features:

I. Structural features

Thread composite design

The oil pipe coupling adopts a composite structure combining conical threads and flat threads, which can alleviate the problem of stress concentration at the root of the external thread when connecting with a single conical thread and reduce the risk of fatigue fracture through the complementary effect of the two types of threads.

Material suitability

The material of the body is usually made of the same grade of steel as the tubing (e.g. API standard steel grade), which ensures that the strength and corrosion resistance of the connection part matches the downhole environment.

Functions

Enhance connection strength

The composite thread design effectively disperses the load, reduces the stress concentration of the tubing column under dynamic loads (such as vibration and shock), and reduces the incidence of tubing breakage.

Simplify operation process

The standardized threaded interface design facilitates quick installation and disassembly, improves operational efficiency, and meets the needs of tubing connection in different well depths.

Performance Advantages

Optimized fatigue resistance

Optimization of stress distribution significantly extends the service life of tubulars in complex well conditions (e.g., inclined wells, horizontal wells).

Suitable for complex well types

The high sealing and torsion resistance of the threaded structure can cope with high temperature and high pressure wells, large displacement wells and other special working conditions.

The design of tubing couplings always focuses on reducing downhole failures, and its composite thread technology has become a mainstream solution to improve the safety of oil well tubing columns.
