WRV-8000 Pipe Plug

The WRV-8000 is an expansion plug intended for sealing pipe openings below the water surface. It is used for planned operations during maintenance, in-water survey or repair, as well as for emergencies and salvage operations.

A watertight seal is established against the inside of the pipe by closing the turning bar, pressing the aluminum disks together and expanding the soft rubber rings. The crossbar prevents the plug from being sucked in. The through-bore and valve (exception: Type A) enable the pipe to be flooded before removing the plug.

Pipe plugs with higher diameter can be customized and delivered with PVC sheeting to provide neutral buoyancy for easy handling under water. Miko marine also can customize pipe plug with pipe cover to provide double barrier sealing. Send enquiry for more information.
