  • Use of calcium sulfonate based threaded compounds in drilling operations and other severe industrial applications
    Patent number: 7294608
    Abstract: The present invention discloses the use of calcium sulfonate based greases compounds for use in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces such as those present in threaded connections, and, especially in threaded connections associated with oilfield applications. The present invention also discloses methods for making and using such greases and compounds in application where the compounds are continuously, periodically or intermittently exposed to fluids that tend to contamination, erode, ablate or otherwise remove or interfere with the compounds ability to protect contact surfaces.
    Type: Grant

    Date of Patent: November 13, 2007
    Assignee: Jet-Lube, Inc.
    Inventors: Donald Oldiges, Herschel McDonald, Tom Blake
  • Non-metallic thread sealant and anti-seize compound having improved anti-galling properties for metal alloys
    Patent number: 7091161
    Abstract: An anti-seize compound is disclosed for use on surfaces of threaded connections made of speciality alloys such as high nickel or chrome ferrous alloys or other speciality alloys prone to galling under high stress conditions. The compound using a metal fluoride as the anti-seize film forming agent at least above about 5 wt %.

  • Resin bonded particulate anti-seize agent, lubricating system made therefrom and methods of making and using same
    Patent number: 6960555
    Abstract: A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a particulate fluoride anti-seize agent designed to bond a particulate fluoride film to the thread surface to prevent seizing and galling. A anti-seize lubricating composition is also disclosed where an environmentally friendly lubricating composition is applied as a top coat to the bonding composition and to methods for making and using the compositions.
