Abstract

A combined hub joint and connector arrangement for rigidly connecting two axially consecutive tubular members is shown. The tubular members have respective hub end surfaces to be mated, where each hub further includes a flanged end having an external tapered activation surface adapted for complementary engagement with an internal tapered activation surface of the connector, The activation surfaces are able to transform a transversally acting force, when viewed in the longitudinal direction of the joined hubs, to an axially acting force when the connector is activated to make up the joint. The hub end mating surfaces diverge at least over some area of said mating surfaces and opens up in a radially outwards direction. The connector can either be a clamp connector, collet connector or split ring connector.
