Lifting subs are mainly used as special tools for lifting drill collars, drill pipes and other downhole drilling tools in oil, gas and geological drilling operations.
The structural forms of lifting subs are divided into two types: A and B. Type A is an 18° shoulder and type B is a 90° shoulder. When using, you can choose type A or type B lifting subs according to the structural type of the elevator. The thread form is adapted to the drill string it is connected to. The lifting diameter is used for the elevator to clamp.
