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 recess cooperating with a test slide to block flow through the fitting. An externally accessible port allows insertion and removal of the test slide. The test slide has an internal recess in which a pressure release slide moves to open a hole to release pressure, and to close the hole to block flow through the fitting for pressure testing. After testing and the release of the fluid test pressure, 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.

Dual slide gate valve and method for using same

An elongated strap has a plurality of openings sized to hold plumbing pipes extending through the openings. The openings have a periphery that undulates so the periphery extends on opposing sides of the strap to increase the periphery in contact with the pipe along the longitudinal axis of the pipe. A fluid-tight pipe cover releasably connects to further openings in the strap. The pipe cover has a first, open end sized to fit over the pipe. The open end has projections cooperating with the further openings to releasably fasten the cover to the strap. The cover has a closed, distal end that extends beyond the distal end of the pipe during use of the device. A seal is interposed between the cover and the pipe during use of the device to prevent the passage of fluid from the pipe past the seal.

Pipe protector and support

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.

Method and apparatus for pressure testing pipe lines

An elongated strap has a plurality of openings sized to hold plumbing pipes extending through the openings. The openings have a periphery that undulates so the periphery extends on opposing sides of the strap to increase the periphery in contact with the pipe along the longitudinal axis of the pipe. The undulations are preferably formed by flutes having an enlarged end opening onto the periphery.
