China suppliers API 7K High Quality Pneumatic safety Spinning Wrenches for oil and well drilling

1.Model: SSW40

2. applicable drill pipes and drill collars size: 3 1/2~9 1/2 in

3.It is mainly composed of two symmetrical components, each of which drives the gear transmission through air motor and drives the wheel rotation.

4. The spinning wrench is a kind of wheel-type spinning tool,

5. the spinning wrench boasts the advantages of large speed, no slippery and no damage to drill pipe,

6.can be used in oil and mud environment,.with the advange of safety and reliability.

7. brake torque : 1100ft-lbs(1490 N.m) and the in and out spinning speeds are large

8. During the tripping operation, SSW40 wrench substitutes the spinning rope (spinning chain), so as to make the spinning operation safe and reliable, reduce the labor intensity of drillers, and promote the tripping speed

9. The air motor in the spinner can rotate clockwise and anticlockwise, which makes coring and treatment of drilling troubles more convenient.

Operation principle  

Operate the air valve with air spring to make the wheel compress the drill pipe; control the air motor valve handle, control the air motor valve handle, and start the left and right motors. The motors drive respective drive wheel through left and right reductin units. Due to the friction torque, the drill pipe rotates, and the pipe screw thread rotates in or out. The opening of wrench can adapt pipes of different diameters through adjustment without need for exchange of wheel, which makes manufacturing, application and maintenance more convenient.
