Pneumatic plugs with bypass (PPB)
Designed for bypassing of fluid or gas transported in the pipeline around the site of repair works.
The plug is designed in the form of a toroid-shape shell of rubberized fabric within a metal case with end-to-end port and tube for connection to the rubberized fabric hose used for the bypassing of the transported fluid or gas.
Plugs are used to keep the pipeline operating while repair works are being performed on a specific section of the pipeline or to check (test) the tightness of the pipeline and to eliminate clogging.
