Abstract
A flow restriction system for restricting fluid flow through a pipe includes an anchor and an inflatable plug. The anchor includes an alignment body, a shield body, and a first fluid passage defined in the alignment body and the shield body. The shield body extends from the alignment body and has an upstream face and a downstream face. The downstream face is opposite the upstream face. The shield body is configured to block at least a portion of the fluid flow through the pipe. The inflatable plug is coupled to the downstream face of the shield body. The inflatable plug includes an interior chamber that is in fluid communication with the first fluid passage.
Claims20
A flow restriction system for restricting fluid flow through a pipe, the flow restriction system comprising:
- an anchor including:
- an alignment body,
- a shield body extending from the alignment body, the shield body having an upstream face and a downstream face opposite the upstream face, the shield body configured to block at least a portion of the fluid flow through the pipe, and
- a first fluid passage defined in the alignment body and the shield body;
- and
- an inflatable plug coupled to the downstream face of the shield body, the inflatable plug including an interior chamber, the interior chamber in fluid communication with the first fluid passage.
A method of restricting fluid flow through a pipe, the method comprising:
- inserting a shield body of an anchor into the pipe, thereby producing a pressure differential in the fluid flow through the pipe;
- and
- inflating an inflatable plug connected to the anchor downstream from the shield body to seal the pipe.
