Title:
JOINTS HAVING IMPROVED SEALABILITY, LUBRICATION AND CORROSION RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2012/010981
Kind Code:
A3
Abstract:
Embodiments of the present disclosure provide systems and methods for assembly of tubular joints which overcome the drawbacks and limitations of conventional joints. In certain embodiments, the tubular joints may comprise threaded joints used in oil exploration. Joints may be assembled using a combination of a) position control, b) specific production tolerances for thread parameters, and c) coatings applied on threaded areas of the joint. In further embodiments, the tubular joints may have no torque shoulder and/or metal to metal seals. In additional embodiments, the joints may be further assembled and disassembled several times without application of dope or grease and exhibit enhanced sealability. Beneficially, embodiments of the present disclosure may provide high tolerance, precisely assembled joints that provide improved performance (e.g., mechanical performance, sealability, corrosion resistance, lubrication) and reliability over non-premium connections without the expense associated with premium connections.
