Multi-size Municipal Blocking Plugs

Municipal series blocking pipe plugs can be build up with high-quality natural rubber, NBR, neoprene rubber, or other material. Nylon layers were used to reinforce it. This ensures our inflatable pipe stoppers are resistant to fuel, petro-chemicals, and other caustic chemicals. Each inflatable pipe plug is equipped with rigging hardware, inflation ports, and pressure relief valve.

And, 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 important easy and quick removed because of its lightweight.

Municipal series blocking stoppers are lightweight plugs designed for commercial and light industrial work. Their small deflated size makes insertion and operations fast, easy, and safe. Filling the plugs with air or inert gas lets them expand to completely block pipes for maintenance, construction, or other projects. Use these economical and lightweight inflatable pipe plugs for buildings and factories or wherever a shorter pipe plug is required. All municipal blocking pipe plugs all use standard valves for easy inflation and deflating.

Municipal Blocking Pipe Plugs Specification

We provide a broad size range from DN300mm to DN3500mm in diameter for heavy-duty projects all over the world. The plugs can withstand high working pressure. The working pressure of enhanced type pipe stopper is 0.1 ~ 0.18Mpa. The high-pressure working pressure can reach 0.3Mpa. Thereby, the safety of construction can be better guaranteed. Other specifications and other operating pressures can be customized according to customer needs.
