Product Details

High-pressure water blocking airbags are specialized devices used for temporary water blocking, pressure testing, maintenance, and inspection in pipelines, culverts, tunnels, and other engineering projects. They achieve sealing through inflation, effectively stopping water flow and are suitable for various complex working conditions.

Product Features

1. High-Strength Material
   - Made from high-strength rubber and reinforced cord fabric, offering excellent pressure resistance, tensile strength, and wear resistance.
   - The outer rubber layer is corrosion-resistant and aging-resistant, suitable for various environments (e.g., sewage, chemicals).
2. High-Pressure Performance
   - Wide working pressure range, capable of withstanding high internal pressure, usually 0.15 Mpa and 0.2 Mpa, 0.15 Mpa can be blocked within 5 meters of water depth, 0.2 Mpa can be blocked within 10 meters of water depth..
   - Burst pressure is significantly higher than working pressure, ensuring safe use.
3. High Flexibility
   - The airbag is foldable, making it easy to transport and install.
   - Suitable for pipelines or holes of different diameters, with good adaptability.
4. Excellent Sealing Effect
   - After inflation, it tightly adheres to the pipe wall, achieving efficient sealing and preventing water leakage.
   - Suitable for pipelines with circular, oval, and other cross-sectional shapes.
5. Easy Operation
   - Inflated quickly using an air pump, saving time and labor.
   - Equipped with a pressure gauge and safety valve for easy monitoring and control of internal pressure.
6. High Durability
   - Reusable, cost-effective.
   - Suitable for various environments, including high temperature, low temperature, and humidity.

Main Applications

1. Pipeline Water Blocking
   - Used for temporary water blocking in municipal drainage pipelines, sewage pipelines, and rainwater pipelines.
   - Suitable for water flow interruption during pipeline maintenance, renovation, or inspection.
2. Pressure Testing
   - Used for pipeline pressure testing to check the sealing and pressure-bearing capacity of pipelines.
3. Culvert and Tunnel Construction
   - Used for temporary water blocking during culvert and tunnel construction to ensure a dry working area.
4. Emergency Rescue
   - Used for rapid water blocking in emergencies, such as pipeline bursts or flood backflow.
5. Industrial Applications
   - Suitable for water blocking and maintenance in industrial pipelines, such as those in chemical plants and power plants.
