The SSW40 pneumatic spinning wrench is the best replacement of rotary
rope (or chain). It is applied for the mechanized spinning operation. The
applicable range of pipe diameter is wide, and it can be freely adjusted
whenever necessary. There are two configurations for clamping mechanism: air
tyre and air cylinder. There are two driving and controlling styles: pneumatic
and hydraulic. The spinning wrench is designed and manufactured according to
API Spec 7K “Specification for Drilling Equipment”. Proving the old saying that
“Good things come in small packages”, the SSW-40 is not only small in size but
also the most powerful pneumatic spinning wrench on the market. Designed with
the operator in mind, the controls are simple and positioned for ease of
handling. An easy adjustment screw eliminates the need of change rollers and
can accommodate drill pipe and drill collars from 3 1/2" to 9 1/2"
OD. The National Oilwell Varco SSW-40, proven and tested to National Oilwell
Varco’s strict standards for performance and reliability, revolutionizes old
ideas about how a spinning wrench should look and work. The speed of the
SSW-40’s four drive rollers, powered by two motors, is precisely controlled by
the operator to permit the slow walking in of drill collars or fast spinning in
or out when tripping pipe. In a typical spinning operation the rig hand swings
the SSW-40 onto the pipe just above the joint upset. The clamp control is
pulled and the throttle handle actuated to spin in or out with absolute
direction lockout feature is included to prevent spinning pipe in wrong
direction, and comes with added safety valve, which prevents the tool from
being closed without pipe in tool.
