    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.

    Abstract: The present invention aims to offer a lubricating composition with excellent heat resistance, mechanical stability, water resistance, corrosion resistance, load resistance and flame resistance. To this end the present invention suggests that from 2 to 68 % by weight of tricalcium phosphate relative to the total composition is added to a base oil, which may be a mineral oil and/or a synthetic oil. Surfactants are further added, and the whole is thoroughly mixed and kneaded to give a semi-solid lubricating composition. For the surfactants, non-ionic surfactants are most suitable, and fatty acid esters such as glycerine fatty acid esters, sorbitan fatty acid esters and sucrose fatty acid esters may be used. The amount used is from 0.2 to 18 % by weight relative to the total composition.
