Rubber inflatable pipe plugs are a type of internal intercepting flow device made from high-quality rubber, featuring excellent burst strength, elasticity, and flexibility. They are primarily used for intercepting flow in drainage pipelines and are widely applied in the fields of water supply and drainage, civil engineering, and fire rescue. This inflatable bag expands through air injection, causing its wall to closely adhere to the inner wall of the pipeline, thereby achieving the purpose of sealing the pipeline.

- Pipeline maintenance. During pipeline repairs or replacements, the rubber inflatable pipe plug can be used for temporary sealing to prevent sewage or pollutants from entering the pipeline.
- Pipeline inspection. During pipeline internal inspection, rubber inflatable pipe plugs can be used to isolate the inspection area, ensuring a clean inspection environment.
- Drainage system maintenance. In urban drainage system maintenance, rubber inflatable pipe plugs can be used to block drainage pipelines for water-tight testing or cleaning operations.
- Industrial pipeline cleaning. In the process of industrial pipeline cleaning, rubber inflatable pipe plugs can be used to isolate the cleaning area, preventing leakage of cleaning fluids.
- Construction. In construction, rubber inflatable pipe plugs can be used for temporary sealing of pipelines to prevent contamination and damage during the construction process.
