Pipeline plugging airbag Pipeline plugging airbag is a multi-specification and multi-shaped rubber used for pipelines, culverts, sewage, sludge removal and maintenance made of polymer synthetic materials such as rubber and fiber fabrics through a high-temperature vulcanization process. It can quickly block the water flow on different pipe diameters, different planes and different positions, and is an ideal tool for underground pipelines for drainage and sludge treatment. The construction method of the pipeline blocker (pipe blocking airbag) The working principle of the pipeline blocking airbag for water blocking is to use the pipeline blocking airbag made of high-quality rubber to expand it by inflation. When the gas pressure in the water blocking airbag reaches the specified value When required, the water blocking airbag fills the entire pipeline section, and the frictional force generated by the pipe blocking airbag wall and the pipeline is used to block the water leakage, so as to achieve the purpose of no water seepage in the target pipe section.
The models of pipeline blocking airbags are: pvc air nozzle capsule, composite water closing plug, air nozzle water closing plug, double-isolated inflatable capsule
The pipeline blocking airbag is especially suitable for the maintenance and testing work such as closed water test, closed air test, leakage point search, temporary water blocking for pipeline maintenance after sealing the drainage pipeline.

The pipeline blocking airbag is mainly aimed at the pipeline blocking of horizontal pipelines (ie horizontal pipelines), and is characterized by:
1. Oval type, the contact area of the pipe is not much, but it is easy to plug into the pipe, and the water blocking effect is average.
2. Simple operation, light weight, small size, economical and practical.
3. The airbag can be bent 180 degrees freely and has certain corrosion resistance.
4. Super expansion.
The pipeline water blocking bladder is made of reinforced natural rubber. Before delivery, each pipeline water blocking bladder will be tested under the conditions of 1.5 times the rated working pressure and the corresponding type of pipe diameter. In order to ensure the strength of the pipeline water blocking airbag structure, we use a safety factor that is three times the rated working pressure of the pipe sealer.
The pipeline water blocking air bag is composed of air bag, pressure gauge, tee, 6 meters long special air pressure hose, and pump. In the building floor closed water test, it can withstand the natural pressure of 2-6 floors of water.
The pipeline water blocking airbag is especially suitable for the maintenance and testing work such as closed water test, closed air test, leak point search, temporary water blocking for pipeline maintenance after sealing the drainage pipeline.
The pipeline water blocking airbag is mainly aimed at the pipeline blocking of the riser (that is, the pipeline inserted from the inspection port). The characteristics are:
1. The operation is intuitive, directly observe the pressure operation of the pressure gauge, and inflate according to the standard pressure.
2. The body size is small, easy to plug into the pipeline, economical and practical.
3. The airbag can be bent 180 degrees freely and has certain corrosion resistance.
4. It is made of reinforced natural rubber with super expansion.
