Product Description
Directional Drilling Use Non Magnetic Crossover Sub
The Crossover subs are mainly used in oil, gas and geology drilling process to connect upper and lower drill tools with different connectors in drilling operations. They are used for crossing over from the size of a single connection to the other and used for prolonging the life of the more expensive components of the drill stems along with well structure and superior performance.
Crossover subs can also be used to protect other tooling in drill stem (called saver sub) or be used to deliver outgoing air to the bit face just above the bit (called bit sub).
Crossover subs are available in three forms with end connections, they are a box x box, box x pin, and pin x pin configuration. The threaded connections are also protected by a durable phosphate surface coating that helps reduce galling during the initial make-up.
Our AISI4145H and Non Magnetic P550 P530 standard Steel Crossover Subs (X-over Sub, Drill Stem Sub, Top Drive Sub, Lift Sub, Saver Sub, Side Entry Sub, Circulating Sub, Wear Sub, Oriented Sub ) are available with all size and manufactured to conform to API specifications.
According to the different connecting components, there are "A","B"and "C" types to crossover subs.
