Improved Safety

The implementation of Test Pups during the mechanical completion of a plant offers the project manager substantial safety benefits.

Installed during the early phases of process piping construction, the Test Pup jumper spools can remain in position until testing and pre-commissioning has been completed.

The Test Pup method reduces valve hopping, and consequently the double handling of temporary jumper spools and permanent inline equipment.

The technology can also be used during maintenance in the event of loss of containment and the failed isolation of control valves.
