ROTARY SUB AND OTHERS
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 connection size to another or as the disposable
component used to extend the connection life of a more expensive drill
stem member.
Lift Sub
A Lift Sub enables 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 Plug
The Lift Plug is a small easy-to-handle sub that makes up in the top of
the drill collar. It has a lifting flange that serves as a safety stop when
drill collars without elevator recesses are being tripped out of the hole.
The center section of the Lift Plug is bored out to reduce weight for easy
handling.
Saver Sub
Saver Sub is used to extend the life of the Kelly by taking the connection
wear each time it is make-up 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 Kelly connection.
Straight OD Sub
Straight OD Sub is used 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 Sub
Reduced Section Sub is used to connect drill stem members that have
different diameters that warrant the cross-sectional change necessary to
accommodate different connections. This sub would be used to crossover
large OD drilling tools or a tapered drill collar string.
