any finished casing/connection combination not carried in inventory can be furnished
in 7 to 10 working days.
Specialty Connections
In addition to a strong tubular inventory position, GB Tubulars has developed a number
of specialty casing connections for a variety of service. In 1980, GB Tubulars introduced
the GB W Butt Connection for 20" OD Casing. This specialty connection replaced API BTC
Couplings, which have square bearing faces that tend to catch the lip of standard 21 ¼"
BOP stacks, and hang up while lowering the string. GB Tubulars’ founder, George Geary,
seized the opportunity to solve this problem with a connection that would self-center through
the restriction in the BOP. The GB W Butt, a weld-on Connector with tapered shoulders, saved
rig time and was an immediate commercial success.
Since that time, GB Tubulars has custom designed over a dozen project-specific connections
for Shell, Chesapeake Energy, ChevronTexaco, and others. In 2005, GB Tubulars introduced
the next generation of Casing Connections, the GB Drilling with Casing Connections. These
innovative coupled connections are suitable for all types service; Running (standard static
casing applications), Rotating (to aid string advancement), Drilling (Drilling with Casing/Drilling
with Liners) and Driving.
