RECENT UPDATE(S)
December 2005:

GB Tubulars announces new connections for Drilling with Casing. These innovative connections use API BTC pin threads in an innovative coupling designed for high rotational fatigue resistance. Connections can be equipped with integral, sacrificial wear sleeves and wear sleeves with hardfacing for use in drilling through hard formations. Please give us a call or send a request for information through the “Contact Us” link on this page for more information.

April 2003:

1) The Running Procedures for all GB Connections have been revised. The
    revisions provide more information for casing crews and thread representatives
    running casing with GB Connections. The nature of the revisions include:
   a) Addition of a section discussing the proper use and interpretation of torque
       vs. turn plots (when available).
   b) Expansion of the Comments section to better explain what questionable
       make-ups are and corresponding corrective actions.
   c) Addition of a picture and a graphic for more realistic presentation of a good
       make-up based on the position of the coupling relative to the triangle stamp.

2) Data Sheets, Drawings and Running Procedures are now available in a Printer
    Friendly pdf file format.
