    摘要: An improved threaded connection for joining tubulars for oil and gas field operations forms connected tubular strings. The improved threaded connection includes a one piece coupling comprising a body with an outer surface an inner surface and a central axis, a first tapered edge, a second tapered edge, first and second bearing faces for supporting load, weight, or both of the connected tubulars, a plurality of torque stops, and radial metal to metal seal surfaces. As the inner surface of the body is swaged onto each tubular, the inner surface of the body deflects away from the central axis, providing a plurality of bands of high contact pressure at each metal to metal seal between the inner surface of the body and each connected tubular to sustain seal pressures at the threaded one piece coupling.

    摘要: Methods and systems for providing cleaning and providing barrier coatings to interior wall surfaces of small diameter nonmetal and composite piping systems in buildings, swimming pools, underground pipes, in-slab piping systems, piping under driveways and various liquid transmission lines. An entire piping system can be cleaned in one single pass by dry particulates forced by air throughout the building piping system by an external generator, and the entire piping system can be coated in one single pass by a machine connected exterior to the piping system. Small pipes can be protected by the effects of water corrosion, erosion and electrolysis, extending the life of piping systems such as plastics, PVC (polyvinyl chloride), composite materials, polybutylene. Coatings can be applied to pipes having diameters of approximately ⅜″ up to approximately 6″ so that entire piping systems such as potable water lines, natural gas lines, HVAC piping systems, drain lines, and fire sprinkler systems in single-family homes to apartments to high-rise hotel/resort facilities and office towers, apartment and condominium buildings and schools, can be cleaned and coated to pipes within existing walls. The coating forms at least a 4 mils or greater covering inside of pipes. Buildings can return to service within approximately 24 to approximately 96 hours.
