Multi-size pneumatic plugs (PPD)

Blind pneumatic plugs

Pneumatic plugs are applied when the frontal part of the piping is open or when there is an opportunity to cut large operating opening in the pipe that is equal to overall dimensions of blind air pressure plug.

Pneumatic plugs are designated for pipeline shank bore of different diameters while assuming of emergency measures, repair and adjustment operations performed with oil pipelines, oil-product pipelines, water pipe, sewerage and heating systems (including chemical enterprises).

Pneumatic plugs represent a hollow barrel rubber-cord casing with two flat bottoms. A faucet for filling the cover with compressed air is located on one bottom, a hanger for fixation of the air pressure plug in a piping for removing of compressed air from the cover and draining water that has been collected during the repair process is located on the other one.
