ABSTRACT:
A rugged screw-threaded pipe connector for handling corrosive or contaminating fluids under high pressure in a pipeline or pipe riser surrounded by a body of water and subject to high static or dynamic stresses and bending forces. The connector is provided with coarse threads having stabbing flanks and with load flanks adapted to support high loads. The connector is provided with multiple sealing means arranged within the body of the connector that isolate the threads from fluids outside the connector or within the bore of the connector.
