Inflatable rubber pipeline plugging airbag are applied for underground to seal pipes for installation, repair/maintenance and desilting purpose. The rubber pipeline sealing airbag can block the water promptly. There are several types of rubber plugging airbags according to their working pressure and water pressure as well as working time. Our rubber sealing airbags are manufactured with inner rubber layer, reinforced rubber dipped synthetic-tire-cord layers and stronger outer layers. This design is derived from ship launching marine airbag and heavy lifting rubber airbags. The sealing rubber airbag is durable, with good airtightness, and longtime lasting under bigger water pressure.
Rubber plugging airbag features
a. sizes can be customrized as per pipes specification
b. suitable for pipelines with different materials
c. good airtightness, wear resistance, anti-aging
Sealing rubber airbags usage procedure
1. When we open a new sealing airbag, the first step is to inspect his airtightness to avoid airleakage.
- Equipped full set of inflating accessories onto mouth of plugging airbags, then inflate them to required pressure, keep some time to test the inner pressure and test the airtightness.
2. Clear the inner wall of water pipeline, without any needles, sands and small stones, keep it smooth.
3. Place rubber airbags into pipelines slowly, but away from joints, each size of rubber sealing airbag is suitable for each type pipeline.
4. Inflate airbags to standard pressure and further tie inflatable tube to airbag mouth.
5. Closely watch the changes of airbags pressure until project finished.
