product description
Imported rubber and high molecular aramid materials are used, with the characteristics of sustainable expansion. The variable diameter airbag is mechanical
The die-casting integrated vulcanization mode has high rubber density and
Extremely high bearing pressure 0.25Mpa, one specification of airbag can be divided
Do not block several pipes of different specifications,
For example, DN300-600MM can block all pipes within the range of 300-600mm. Convenient, fast and safe.

Material design: three-layer structure composition-high -quality special natural native rubber+special strength and corrosion-resistant fabric structure layer+high-quality special natural native rubber;
The two ends are fixed with special stainless steel structure and one-time vulcanization molding process. This structure and material will make the air bag lighter and more durable.
Product Detail
Scope of application
The pipe water plugging bladder is suitable for maintenance and testing such as water closing test, air closing test, leak point search, temporary water plugging for pipe maintenance after sealing the drainage pipe
Usage method
Place the plugged air bag at the pipe opening to be plugged. The length of the plugged air bag is the length of the plugged air bag. Then, flush the compressed air through the air inlet valve to the specified pressure. After the construction, open the air inlet valve to release the air and take out the plugged air
