H type safety joint is down hole safety assembly. It is built to withstand all kinds of loads (axial pulling or pressing) and it aid in torque transmission. In down hole operations, safety joints are normally added to the drill string as a precaution to support any tool recovery emergencies. The safety joint allows quick release and disengagement of the tool should they become stuck, so that the drill stem above can be removed. On top of that, while resuming the down hole operation, the safety joint ensures quick and easy reconnection of drill stem.
