Proplug manufactures hydraulically actuated plugs which expand seals and/or gripper jaws into the pipe wall.
The hydraulic system replaces the energising nuts to provide a quick and easy method of plug setting.
The main advantages over mechanical plugs are: -
Speed of Setting The Plug
Remote setting of plug
Single Point Actuation
Smaller Plugs utilise single hydraulic units, whereas larger Plugs couple together multiple hydraulic units which operate together.
There are many applications for this type of plug: -
Temporary End Cap to contain gases and liquids
Pigging Operations (Temporary Closure)
Spool and Jumper Hose Plugging
Fluid Retention/Containment Plugs
Subsea and Topsides Use
External Pipeline Plugging
