Abstract
An apparatus and method for hydrostatically testing pipe is disclosed. Means are provided for externally exerting a force against test plugs sealing the ends of a pipe being tested to oppose forces tending to push the test plugs out of the ends of the pipe. Means are provided for controlling the amount of tension present in the pipe and, alternatively, for creating and maintaining a net compressive force on the pipe during the testing process in order to test characteristics of the pipe.
