Specification

Applications

1. The Key Seat Wiper is placed in the string between the drill pipe and the drill collars.

2. During drill ahead operations, the non-rotating sleeve will not ream the 
formation.

3. In case of over-pull -- when tripping out drill collars or reaming back to shoe through a dogleg – rotate the drillstring while pulling out of hole to cause the clutch ring to transmit rotation to the wiper sleeve and initiate reaming operations.

4. The wiper blades will enlarge the key seat to allow the passage of the bottom hole assembly through potential tight sections of the hole.

When ordering please specify:

Upper and lower neck diameter;

Upper and lower connections;

Circulation bore;

Drill collar O.D. or gauge O.D. of wiper sleeve at blades
