Reusable pipe integrity test head systems and methods

A method, comprising:

• inserting a testing port and a portion of a shell of a test head into a pipe bore defined by pipe segment tubing, wherein the portion of the shell comprises a coned bore insert and the pipe segment tubing comprises a fluid conduit implemented in an annulus of the pipe segment tubing;
• maintaining a reusable fastener mechanism of the test head in a deactivated state while the reusable fastener mechanism is being inserted into the pipe bore defined by the pipe segment tubing at least in part by maintaining wedged clamp segments of the reusable fastener mechanism at a first position on the coned bore insert;
• transitioning the reusable fastener mechanism from the deactivated state to an activated state to facilitate securing an open end of the pipe segment tubing in an annulus cavity defined by the shell of the test head at least in part by rotating an internal threaded fastener that has fastener threading that matingly interfaces with port threading on a testing port that opens through the shell of the test head in a first direction relative to the testing port to facilitate transitioning the wedged clamp segments from the first position to a second position on the coned bore insert that results in the wedged clamp segments covering more of the coned bore insert;
• securing an end cap of the shell between a port ledge on the testing port and an external threaded fastener that has other fastener threading that matingly interfaces with other port threading on the testing port at least in part by rotating the external threaded fastener in the first direction relative to the testing port, wherein the port ledge is between the port threading and the other port threading on the testing port;
• testing of the pipe segment tubing based at least in part on a fluid parameter change resulting from supply of a test fluid to the fluid conduit in the annulus of the pipe segment tubing via the testing port that opens through the shell of the test head;
• and
• transitioning the reusable fastener mechanism from the activated state to the deactivated state to facilitate removing the test head from the pipe segment tubing at least in part by rotating the internal threaded fastener in a second direction relative to the testing port that is opposite the first direction to facilitate transitioning the wedged clamp segments from the second position to the first position or a third position on the coned bore insert that results in the wedged clamp segments covering less of the coned bore insert.

A reusable test head comprising:

• a shell that defines an annulus cavity configured to interface with pipe segment tubing, wherein the shell comprises:
• a coned bore insert configured to be inserted into a pipe bore defined by the pipe segment tubing;
• and
• an end cap configured to externally cover an open end of the pipe segment tubing;
• a plurality of wedged clamp segments configured to slidably interface with the coned bore insert of the shell;
• a testing port configured to be fluidly coupled to the annulus cavity of the reusable test head, wherein:
• the testing port comprises port tubing configured to extend through an opening between the plurality of wedged clamp segments, the coned bore insert, and the end cap;
• and
• the reusable test head is configured to expand an outer surface diameter of the plurality of wedged clamp segments outwardly when the plurality of wedged clamp segments is moved to cover more of the coned bore insert to facilitate securing the open end of the pipe segment tubing in the annulus cavity to enable integrity of the pipe segment tubing to be tested at least in part by flowing fluid between the testing port and a fluid conduit implemented within the pipe segment tubing;
• an internal threaded fastener, wherein:
• the internal threaded fastener comprises fastener threading configured to matingly interface with port threading on the testing port;
• the plurality of wedged clamp segments is configured to be coupled between the coned bore insert and the internal threaded fastener;
• and
• the reusable test head is configured to:
• move the plurality of wedged clamp segments to cover more of the coned bore insert when the internal threaded fastener is rotationally actuated in a first direction relative to the testing port;
• and
• move the plurality of wedged clamp segments to cover less of the coned bore insert when the internal threaded fastener is rotationally actuated in a second direction relative to the testing port that is opposite the first direction;
• and
• an external threaded fastener, wherein:
• the external threaded fastener comprises other fastener threading configured to matingly interface with other port threading on the testing port;
• the testing port comprises a port ledge between the port threading and the other port threading;
• and
• the end cap is configured to be coupled between the external threaded fastener and the port ledge on the testing port.
