Abstract
A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal boss extending around a circumference of the flow path and extending radially inward toward the centerline a distance corresponding to the wall thickness of the mating male ends of the pipes so the pipes and boss define a periphery of the flow path through the fitting. A recess is formed in the boss to sequentially receive two slides. An externally accessible port allows a test slide to be inserted into the recess, with the test slide sealing against the walls defining the recess to form a fluid-tight seal for pressure testing the line. The test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.
