300mm Inflatable Pipe Stopper Pipeline Inflatable Rubber Airbag

Product Description

Product Description

The with Good Burst Strength, Elasticity & Flexibility
    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.

Features

*Good sealing performance. Rubber material has excellent elasticity and air-tightness, allowing for complete sealing of pipelines.
*Highly adaptability. It is suitable for pipelines made of different materials and shapes, such as circular, oval, square, etc.
*Easy installation. The rubber inflatable pipe plug can be quickly installed in place through air inflation, making the operation simple.
*Cost-effective. Compared to other plugging methods, rubber inflatable pipe plugs are more affordable and can be reused.
*Corrosion resistance. Certain rubber materials have good corrosion resistance, making them suitable for sealing pipelines in the chemical industry.
*Environmentally friendly & Safe. Using rubber inflatable pipe plugs does not produce harmful chemicals, making them environmentally friendly.

Function

*Pipeline Blockage: Forms an airtight seal inside the pipe to effectively stop the flow of water, gas, or other media.

*Pressure Testing: Provides a closed environment for pipeline systems to facilitate leak detection and pressure testing.

*Temporary Isolation: Safely isolates specific pipeline sections during repair, renovation, or new construction to ensure work safety.

*Fall Protection: When used in vertical pipes or openings, it prevents the accidental dropping of tools or debris.
