ABSTRACT:
This invention relates to a mobile pipe testing system. The system carries its own supply of a test fluid and an independent power source. During operation, a pipe is lifted by an inbound conveyor and is delivered to a pre-test station, from which it is lifted by the arm and deposited into a testing cradle. The ends of the pipe are sealed by test plugs which are moved into engagement with the pipe ends, and a pressure is applied to the interior of the pipe to test the pipe for possible leakage. Once the test is complete, the test plugs are moved away from engagement with the pipe, and the lifting arm moves the pipe segment into a holding station, wherein the pipe is allowed to drain, while the fluid is filtered, collected and recycled back into a fluid container. The lifting arm then transports the pipe to the outbound conveyor which off loads the pipe.
