Tunneling Length 8.25 Inch T45 210mm Threaded Couplings

Description

Because of different applications, we need different lengths of drill stems, so couplings sleeves are used for connecting extension rods. There are semi-bridge couplings and full bridge couplings, the only difference between them is that semi-bridge couplings have a middle stop at the middle of couplings. Usually couplings two ends are the same couplings, like R25, R32,R38,T45, T51, etc .While sometime people need crossover couplings to work, for example, one end is R32 and another end is R38, but basically all couplings are female threads at the two ends.

 

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
