Brute® Long-Stroke Bumper Subs
Blackhawk’s Brute® Bumper Sub is a heavy duty travel joint that is designed to withstand sustained torque through its full four foot stroke under most severe operations. The Bumper Sub is completely pressure balanced, which permits free travel through the full stroke unaffected by variations in pump pressure and/or hydrostatic pressure. The Bumper Subs may be used as motion compensators on floating rigs, or to allow controlled feed-off on delicate down-hole operations.
- The bore through the tool permits full circulation at all times
- Hexagon mandrel proved large contact area to transmit torque
- Fully compatible with Brute® Storm packer system
