Abstract

A stab type connector for large diameter pipe has a pin structure and a box structure held in interconnected relation by a locking and loading ring between a circumferential shoulder in the pin structure and a circumferential shoulder on a threaded locking and loading sleeve of the box structure with confronting circumferential pin structure and box structure seating surfaces loaded into engagement. The coengaged and loaded sleeve shoulder and ring and coengaged pin and box structure surfaces transmit axial forces through the connector and resist bending. The connector is useful as a conductor pipe or pile connector.
