Mining Equipment Accessories Coupling Sleeve T45 Drill Pipe Coupling
Coupling sleeve,called coupling too,using connect extention rod and shank adapter.We can produce semi-bridge and fully-bridge according to your requirement.
The connecting sleeve is mainly used for the shank and the drill rod and the drill rod and the connecting rod is connected between the. For reducing the connecting sleeve and the connecting sleeve with the same diameter. Main specifications R32, T38, T45, T51 reducer connected set of R25-R32, R28-R32, R32-R38, R32-T38, R32-T45, T38-T45 and, due to the need of energy transfer and handling, on the material properties and processing technology of higher requirements, connecting sleeve of my company's production, the high quality alloy steel forging processing into, the thread processing the special machining center, high machining precision, with good thread and prolong the prolonging the service life of the connecting sleeve.
Specification and function of the coupling sleeve:
Full-Bridge Coupling sleeve
Eliminates the potential for the coupling to creep along the threaded joints
Typically used in surface applications
Better uncoupling characteristics and tend to maintain tighter joints
Less chance of jamming
Best suited to machines equipped with independent rotation.
Semi-Bridge Coupling sleeve
Small non-threaded bridge in the center
Steel cannot thread past bridge area
Smaller diameter steel end portions fit together in the centre bridge area of the coupling
Semi-bridged couplings are most suited to high torque machines
Most rope and T threaded couplings are semi-bridged
Same diameter Coupling sleeve
Eliminates the potential for the coupling to creep along the threaded joints
Typically used in surface applications
Better uncoupling characteristics and tend to maintain tighter joints
Less chance of jamming
Best suited to machines equipped with independent rotation.
