PVC Inflatable Pipe Plug DOOWIN inflatable pipe plugs are flow stoppers for temporary close off or seal an opening. Our inflatable pipe plug/stoppers are very suitable for use in the pipeline, ducts, and tunnels with construction, inspection, repairs, cleaning, and repair. Our inflatable pipe plugs are constructed of high tenacity, urethane coated nylon fabric. We also make it with other special coating material and synthetic-tire-cord rubber layers. This ensures our inflatable pipe stoppers are resistant to fuel, petrochemicals, and other caustic chemicals. Each inflatable pipe plug is equipped with rigging hardware, inflation ports, and a pressure relief valve. DOOWIN inflatable pipe plugs are multi-size flow stoppers. Each flow stopper can be used to close off a range of pipe-diameter. The inflatable pipe plugs are easy to install and as even more importantly easy and quickly removed because of their lightweight. The common size is from DN300 to DN3000. Custom sizes, shapes, and configurations can be designed and manufactured to meet special needs. Each inflatable pipe plug is tested before delivery.
