GB Tubulars’ strength is quick delivery of casing, connections and/or finished pipe from an inventory that is maintained to meet immediate end-user needs. Just about 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.
