The working principle of the pipe sealing airbag is to use the airbag to fill it with gas and expand it, which is closely fitted with the inner wall of the pipe, thereby blocking the passage of water or airflow in the pipe.
When choosing a suitable pipe repair airbag, you need to consider multiple factors such as the size, material, and repair methods of the pipe.
Accurate measurement of the inner diameter of the pipe is the key to choosing an airbag. Different pipe repair airbags have their specific applicable pipe diameter range.
