Abstract:
1. An improved thread protector for tubular goods having threaded ends, the improved thread protector comprising: a polymeric body having cylindrical wall portions defining an interior space therewithin and further having a transverse partition disposed intermediate a first end and a second end of the interior space, wherein the cylindrical wall portions of the first end engage and enclose the threaded ends of the tubular goods; an air vent provided in the transverse partition of the polymeric body for equalizing air pressure inside the tubular goods with air pressure outside the tubular goods while limiting the passage of moisture therethrough; a weather barrier incorporated in the polymeric body for maintaining a moisture resistant seal between the polymeric body and the tubular goods; wherein the polymeric body includes a corrosion inhibiting compound impregnated into the polymeric body during molding of the polymeric body, the material of the polymeric body itself and the inclusion of the corrosion inhibiting compound resulting in a molded polymeric body which does not transmit light and is therefore opaque; and wherein the weather barrier comprises a weather barrier ring disposed at the first end and around the polymer body for providing a weather resistant seal between the polymer body and a surface of the tubular goods adjacent the threads on the tubular goods away from an end of the tubular goods protected by the improved thread protector.
