Inflatable Rubber Pipeline Blocking Airbag Closed Water Test Rubber Balloon for Pipeline

Product Description

Product Description

The with Good Burst Strength, Elasticity & Flexibility

An that blocks and seals pipelines during maintenance, testing, and emergencies. Insert into the pipe, inflate with a standard air pump — the ribbed NR body expands to form a leak-tight 360° seal against the pipe wall. Multi-diameter design: one airbag seals a range of pipe sizes, reducing inventory. Used for sewer and drain water blocking, municipal pipeline isolation, and water pipe sealing. Natural rubber body withstands hundreds of inflation cycles without cracking. Supplied deflated for compact storage and transport.

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.

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.

Usage

    *Pipeline Blockage & Water Stoppage: Used for temporary water stoppage during pipeline repair or renovation.
    *Air Tightness & Pressure Testing: Provides a reliable isolated test unit for newly built or rehabilitated pipeline systems.
    *Construction Safety Protection: Serves as a safety cap for pipe openings during construction to prevent personnel or object falls.
    *Pipeline Cleaning Isolation: Isolates target pipeline sections during high-pressure water or chemical cleaning.
    *New Pipe Connection: Isolates upstream water flow when connecting new and existing pipes (creating a "T-junction").
