摘要:
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 %.
摘要:
A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a metallic flake designed to bond a dissimilar metal to the thread surface to prevent seizing and galling.
摘要:
The present invention discloses the use of nonmetallic, finely divided polymeric or natural fibers in anti-seize thread compound formulations for use on rotary shouldered, oilfield tubular good or tapered threaded connections. The addition of such fibers into formulas that do not contain metallic powders or flakes (typically utilized to provide the anti-galling properties) provides a measurable improvement in the galling and seize resistance properties. Therefore, the incorporation of such fibers provides a film strength improvement in environmentally responsible thread compound compositions, which previously would not provide the level of galling resistance to perform in severe applications such as oilfield directional or geothermal drilling.
摘要:
A coating and bonding composition is disclosed. The composition includes suspending, bonding and thinning agents, and a metallic flake. The composition may be used with an environmentally friendly lubricating composition to form an environmentally friendly lubricating system for protecting threaded connections from galling or other damage. That system may be used in a method for protecting threaded connections that includes the steps of: coating the threads, prior to make-up, with the coating and bonding composition and then coating them with the environmentally friendly lubricating composition, after the coated threads have dried.
摘要:
A thread sealant and anti-seize compound is disclosed. The compound includes a thixotropic base material, such as an aluminum complex grease, a boundary lubricant, such as graphite, and a non-metallic flake, such as mica. The compound may further include a metallic flake, such as copper or a copper alloy, an anti-wear additive, such as molybdenum disulfide, and conventional rust, corrosion and oxidation inhibitors.
摘要:
A method for imparting anti-seize protection and lubricant to threaded connections of protection during make-up and break-out is disclosed which includes adhering a metallic anti-seize film to threads of threaded connections and coating the film protected threads with a lubricating composition to form an anti-seize/lubricating system with reduced adverse environmental impact. The method can also include depositing a bonding film or layer onto the threads prior to adhering the anti-seize film.
