Rock Drill Accessories Coulpling Sleeves
According to different application scenarios, we provide coupling sleeves with standard (half-bridge), full-bridge and variable diameter type.
The standard coupling sleeve, also known as half-bridge type coupling sleeve, has a bridge without thread in the middle of it. The threaded part of the drill rod cannot be screwed through the bridge part of the couplings, and the threaded end can closely adhere to the casing bridge zone. It is particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are half-bridge type. And it is by far the most widely used couplings.
The full-bridge coupling sleeve is with trapezoidal threads, which can completely eliminate the looseness of the coulpling sleeves along the threaded connection. It is mainly used in surface mining, with better disassembly characteristics and firmer connections. The full-bridge coupling sleeve will almost never be stuck, and it is most suitable for drilling rigs equipped with independent rotary mechanisms.
The variable diameter coupling sleeve is used to convert different thread types or thread sizes.
Detailed Product Description
Advantages
High-quality steel Our coupling sleeves are made of high-quality structural alloy steel, and after a special heat treatment process, they can meet the requirements of excavating harder rock layers and have a longer service life.
Advanced manufacturing technology The coupling sleeves adopt advanced thread manufacturing technology and advanced surface treatment technology, and are manufactured according to precise tolerances. They have the characteristics of tight connection, good energy transmission effect, strong wear resistance and easy disassembly.
Strict quality control All the coupling sleeves are strictly controlled to ensure that they have a satisfactory high quality.
