ABSTRACT:
A threaded pipe connection is disclosed comprising a box having internal threads and a pin having external threads for mating with the internal threads of the box. The mating threads exert radial forces on the box and pin creating compressive hoop stress in the pin and tensile hoop stress in the box. A conical sealing surface on the pin between the threads and the end of the pin engages conical sealing surface on the box and forms a metal-to-metal seal when the connection is made up. Means are provided for reducing the radial forces exerted by the threads adjacent the conical sealing surfaces to reduce excessive metal-to-metal contact bearing stress and better distribute the remaining stress in the engaging sealing surfaces while maintaining the contact stress required to provide an adequate seal.
