Safety Joint Type API Downhole Oilfield Fishing Tools
API Oilfield Fishing Tools / Downhole Tools Type AJ Safety Joint
Product Introduction
The safety joint type AJ is an essential safety tool for connecting the pipes in the well. It is used for drilling, fishing, tubing, washover and test operation. Engineered to withstand internal and external pressure, it also features in coarse threads that resist wedging or loosening of the tool during operation. The torque may be transmitted in either left-or right-hand direction.
H type safety joint, which is installed on the position required for subsurface drill stem and can bear in fishing operation all kinds of loads for pulling or pressing and used to transmit torque,is a subsurface safety equipment.In down hole operation,in case of being needed,the safety joint is easy to be discharged off so as to take out the drill stem above it. It is easy to butt the safety joint to go on fishing operation when running in hole again.
