Abstract
A threaded pipe connector which may find application in the petroleum and gas industry, and pipe connections formed with the connector. The connector includes a male element disposed at the end of a first pipe and a female element disposed at the end of a second pipe. The male element is provided with an external tapered male threading and the female element is provided with an internal tapered female threading corresponding to the male threading. A central seal, formed by a male bearing surface and a female bearing surface and bearing against each other and disposed in a central zone of the male and female threading respectively where the threadings have been interrupted, seals the connector when the connector is assembled. The connector and the connected pipes formed from this connector provide a tight seal under high external pressures.
