Abstract
A connector for connecting pipes and for use with power tongs have a die length. The connector includes a body with threaded connection portions at each end of the body on an inside surface of the body. The connector includes a gripping surface defined on an outside surface of the body between the threaded connection portions. The gripping surface is at least as long as the die length. The connector includes a reinforced portion of the body proximate each of the threaded connection portions for increasing resistance to deformation of the body upon being connected with a pipe. The gripping surface and the reinforced portion together facilitate an increase in connection torque of pipes connected with the connector.

A connector for connecting a first pipe with a second pipe using power tongs having a die length, the connector comprising:
- an elongate body extending between a first end and a second end;
- a first connection portion on an inside surface of the body proximate the first end having interference fit threading for connecting with the first pipe;
- a second connection portion on the inside surface proximate the second end having interference fit threading for connecting with the second pipe;
- a gripping surface extending along an outside surface of the body intermediate the first connection portion and the second connection portion for a gripping length at least as long as the die length, the gripping surface comprising a recessed gripping surface, the recessed gripping surface adapted for gripping by the power tongs, wherein at least the portion of the body defining the recessed gripping surface comprises metal;
- and
- a reinforced portion of the body intermediate the first connection portion and the second connection portion for resisting deformation of the body when a connection is made up with the connector,
- wherein the body has a first outside diameter along at least one of the first connection portion and the second connection portion, and a second outside diameter along the recessed gripping surface, the first outside diameter being larger than the second outside diameter.
A connector for connecting a first pipe with a second pipe using power tongs having a die length, the connector comprising:
- an elongate body extending between a first end and a second end;
- a first connection portion with API interference fit threading on an inside surface of the body proximate the first end for connecting with the first pipe;
- a second connection portion with API interference fit threading on the inside surface proximate the second end for connecting with a second pipe;
- a recessed gripping surface defined on an outside surface of the body intermediate the first connection portion and the second connection portion, the recessed gripping surface extending along the outside surface for a gripping length at least as long as the die length, the recessed gripping surface adapted for gripping by the power tongs, wherein at least the portion of the body defining the recessed gripping surface comprises metal;
- and
- a reinforced portion of the body extending along the body intermediate the first and second connection portions for resisting deformation of the body when a connection is made up with the connector, the reinforced portion comprising:
- a first torque stop defined on the inside surface proximate the first connection portion for abutting a first nose of the first pipe when the first pipe is made up in the first connection portion;
- and
- a second torque stop defined on the inside surface proximate the second connection portion for abutting a second nose of the second pipe when the second pipe is made up in the second connection portion,
- wherein the body has a first outside diameter along at least one of the first connection portion and the second connection portion, and a second outside diameter along the recessed gripping surface, the first outside diameter being larger than the second outside diameter.
A method of connecting a first pipe with a second pipe using power tongs having a die length, the method comprising:
- providing an interference fit threaded connector comprising:
- an elongate body extending between a first end and a second end;
- a first connection portion on an inside surface of the body proximate the first end having interference fit threading for connecting with the first pipe;
- a second connection portion on the inside surface proximate the second end having interference fit threading for connecting with the second pipe;
- a gripping surface extending along an outside surface of the body intermediate the first connection portion and the second connection portion for a gripping length at least as long as the die length, the gripping surface comprising a recessed gripping surface, the recessed gripping surface adapted for gripping by the power tongs, wherein at least the portion of the body defining the recessed gripping surface comprises metal;
- and
- a reinforced portion of the body intermediate the first connection portion and the second connection portion for resisting deformation of the body when a connection is made up with the connector,
- wherein the body has a first outside diameter along at least one of the first and second connection portions, and a second outside diameter along the recessed gripping surface, the first outside diameter being larger than the second outside diameter;
- tonging on to the gripping surface and on to the first pipe with a power tong;
- rotating the connector relative to the first pipe to connect the connector to the first pipe at a torque value with the power tong;
- tonging on to the gripping surface and on to the second pipe with the power tong;
- and
- rotating the second pipe relative to the connector to connect the connector to the second pipe at the torque value with the power tong.
