Estimating the term…
A method and system are shown for protecting the threaded ends of tubular goods such as oil field tubulars from physical damage and corrosion due to environmental factors. A thread protector is formed of a polymeric body having cylindrical wall portions which engage the threaded ends of the tubular goods. Instead of relying upon a separate thread compound or corrosion inhibitor applied to the exposed threads, the polymeric body has incorporated therein a corrosion inhibiting compound, which is integrally molded within the polymeric body as a part of the manufacturing process used to mold the polymeric body. The method also allows used end caps to be recycled into the corrosion resistant end caps of the invention.
An improved thread protector for tubular goods having threaded ends, the improved thread protector comprising:
In combination with an oil field tubular having threaded ends,
