✦ Synopsis

Tenaris Connections AG, Switzerland

A further variation of the threaded joint for oil and gas pipes is described. It creates a metalto-metal seal externally to the female thread. The joint has an extension of the box beyond the seal, which produces an elastic tightening band effect on the seal so that excessive interference on the seal is not necessary. This facilitates correct assembly of the joint.
