Hydraulic Plugs

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

Hydrotesting Pipes

Pigging Operations (Temporary Closure)

Spool and Jumper Hose Plugging

Fluid Retention/Containment Plugs

Subsea and Topsides Use

External Pipeline Plugging
