Water Blocking Airbag Closed Water Pipe Sealing Airbag Inflatable Rubber Water

Product Specification

Sewage Pipe Plugging Airbag Inflatable Rubber Water Stop Plugging Thickening
 
The water plugging airbag is an efficient, flexible and non-destructive temporary pipe plugging tool. The core principle is to achieve sealing through inflation. It plays an important role in many fields such as pipeline maintenance, testing, municipal construction, emergency rescue, etc.
 
Description

• Airbag body: Made of high-strength, high-elasticity, wear-resistant and corrosion-resistant rubber material. The shape is usually cylindrical or slightly rugby-shaped to fit into round pipes.

• Inflation system:

        Air nozzle: Used to connect inflation equipment (such as air pumps, inflators, compressed air sources).
        Air valve: Usually a one-way valve to ensure that the gas does not leak after inflation, and can also be used for deflation when necessary.
 

• Fixed device: Metal pressure plates, pull rings or rope fixing points may be designed at both ends or specific positions of the airbag to position the airbag before inflation or to apply additional fixing force in the pipe (especially in vertical pipes or high pressure difference).

• Safety accessories: Some airbags are equipped with pressure gauges and safety deflation valves to monitor and control the internal air pressure to prevent overpressure bursting.

Application

• Water conservancy projects
• Highway bridges
• Construction sites
• Rainwater and sewage diversion
• Municipal engineering
• Water-tightness test

Features:

• Quick and convenient: Fast installation and removal, no complicated welding or concrete work required.
• Adaptable: The inflation volume can adapt to the changes of different pipe diameters within a certain range (usually there are specific models corresponding to the pipe diameter range).
• Good sealing: After inflation, it can fit tightly to the irregular pipe wall to form an effective seal.
• Reusable: Good quality airbags can be used many times and are economical.
• Non-destructive: Will not cause permanent damage to the inner wall of the pipe (provided that it is used correctly).
• Pressure resistance: Designed to withstand the water pressure in the pipe (with a clear rated working pressure).
• Portability: Small volume after deflation, easy to carry and transport.

• Correct selection: The appropriate model and specification must be selected according to the inner diameter of the pipe, the maximum water pressure/pressure difference to be withstood, and the material of the pipe. The diameter of the airbag should be slightly larger than the inner diameter of the pipe.
•  
• Pipeline inspection: Before use, carefully check whether the inner wall of the pipe is smooth and whether there are sharp protrusions, burrs, welding slag, etc., which will puncture the airbag. Clean it if necessary.
•  
• Cleaning and lubrication: Clean the contact area between the airbag surface and the inner wall of the pipe. Water or special lubricant (avoid oil base) can be applied to the surface of the airbag to facilitate insertion and removal.
•  
• Proper placement: Place the airbag accurately at the predetermined blocking position.
•  
• Slow inflation: According to the manufacturer's instructions, use a suitable pressure source (usually a manual air pump or a small air compressor) to inflate slowly and evenly. Avoid instantaneous high-pressure shock.
•  
• Monitoring pressure: Use a pressure gauge to monitor the pressure inside the airbag. It is strictly forbidden to exceed the rated working pressure of the airbag. The actual working pressure should be slightly higher than the maximum water pressure in the pipeline.
•  
• Fixing measures: For vertical pipes, large-diameter pipes or high-pressure differential occasions, be sure to use the airbag's own fixing devices (such as pull ropes, pressure plates) for additional reinforcement to prevent the airbag from being displaced or squeezed out by water flow.
•  
• Safety protection: Operators should be in a safe position, especially during the inflation process, to prevent accidental rupture and injury. When working in the pipeline, comply with the safety regulations for confined space operations.
•  
• Regular inspection: During the long-term blocking process, regularly check whether the airbag pressure is stable and whether there are any signs of leakage.
•  
• Smooth deflation: After the operation is completed, slowly open the deflation valve and carefully remove it after the airbag is completely deflated.
•  
• Maintenance: Clean the airbag after use, check for damage, and store it in a cool and dry place, avoiding direct sunlight, high temperature, oil stains and sharp objects.
