ABSTRACT:
The present invention generally relates to a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to methods and apparatus for connecting the tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars. A connector mechanically mates a box end and a pin end of the tubulars together to form the connection. Additionally, mating castellations, surface finishes on the pin end and the box end, torque screws, and a variable pitch groove can provide resistance to relative rotation between the tubulars at the connection.
