He has made significant contributions to the field of seal technology, particularly for applications in high-temperature environments. His innovative designs have been instrumental in enhancing the performance and reliability of seals used in various industrial applications.
Latest Patents
Kyker holds a patent for a "Seal structure for elevated temperature service." This invention features a unique design that comprises a sandwich of a soft, low modulus resinous layer between two outer layers of harder, high modulus resinous material. This configuration provides an effective high-pressure seal at both low and high temperatures. The seal is particularly useful in wellhead services, such as blowout preventers or stuffing box seals, in oil wells, geothermal wells, and hydraulic mining pipes. The high modulus material is preferably a polybenzimidazole containing 5 to 50 wt. % short fibers. The low modulus material is ideally a thermoplastic fluorinated hydrocarbon polymer or a fluorinated synthetic elastomer containing polybenzimidazole in powder and/or short fiber form, along with short fibers of glass and/or carbon. For blowout preventer service, the seal can be designed in a T shape to be fitted with complementary metal retainers, forming a cylindrical seal unit with a semicylindrical groove in the seal face to mate with the polish rod or tubing.
