API Standard saver sub and Crossover Sub With High Quality
Detailed Introduction of Saver Sub Saver sub is used to extend the life of the bit by taking the connection wear each time it is make
to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or inexpensively replaced. The saver sub can be equipped with a rubber protector to reduce BOP equipment and casing wear resulting from contact damage with a lower bit connection.
Drill Crossover Subs are used as an adapter between two different types or sizes of threads.
A bit sub is a sub that is used just above the bit and serves as a crossover between the drill collar connections and the bit connection.
