sleeve coupling-manufacture,factory,supplier from China

Standard coupling sleeve, also known as semi bridge coupling sleeve, has a section of the bridge without a thread in the middle. The threaded part of the drill pipe cannot be screwed through the bridge part of the coupling, and the end of the thread can closely adhere to the casing bridge zone. Standard coupling sleeve is particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are with half-bridge type.

Coupling Sleeve is a high-performance coupling sleeve designed for mechanical systems, dedicated to providing outstanding durability and reliability.
