Product Overview
CAMTOP Rotary Subs are made from 4145 H modified quenched and tempered material to API specifications, and carry the API monogram. They can be used to crossover from one connection size to another, or as a disposable component used to extend the connection life of a more expensive drill stem member.
Rotary Sub Types
Lift SubEnables the safe, efficient handling of straight OD tubulars such as drill collars, shock tools, jars, directional equipment and other tools by using the drill pipe elevators. |
Lift PlugA small, easy-to-handle sub that makes up on top of the drill collar. Its lifting flange serves as a safety stop when drill collars without elevator recesses are tripped out of the hole. Center section is bored out to reduce weight. |
Saver SubUsed to extend the life of the Kelly by taking the connection wear each time it is made-up to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or inexpensively replaced. Can be equipped with a rubber protector. |
Straight OD SubUsed to connect drill stem members that have a similar outside diameter. The drill bit, downhole tools, heavy weight drill pipe and drill pipe can be crossed over using a straight OD sub. |
Reduced Section SubUsed to connect drill stem members that have different diameters requiring cross-sectional change to accommodate different connections. Suitable for crossover of large OD drilling tools or tapered drill collar string. |
