Bridge inflatable core mold octagonal circular rubber airbag for highway bridges

Pipeline Emergency Repairs: Ideal for quickly blocking water flow during drainage and sewage pipeline emergencies, enabling rapid repair work.

Leak Detection in Closed - water Tests: Widely used in closed - water test leak detection to ensure the integrity of pipelines. It can effectively block water in different pipe diameters, planes, and positions, making it the perfect choice for underground pipeline water transmission, drainage, and sludge treatment.

High - Quality Materials: Constructed from enhanced natural rubber, ensuring durability and excellent sealing performance. Each airbag undergoes strict testing at 1.5 times the rated working pressure and corresponding pipe diameter conditions before delivery. A safety factor of three times the rated working pressure of the pipe sealer is adopted to guarantee the structural strength of the airbag.

Versatile Sizes: Available in a variety of sizes to fit different pipe diameters, providing flexibility for various pipeline applications.

Easy to Operate: The operation is straightforward. Just insert the airbag into the pipeline, inflate it to the appropriate pressure, and it will quickly and effectively block the water flow.

Good Flexibility: The airbag can be freely bent 180 degrees and has certain corrosion resistance, adapting to different pipeline installation environments.
