Natural Rubber Pipeline Plugging Water Stop Airbag
The pipeline blocking airbag is a kind of in-pipe interception equipment with good anti-expansion strength, good elasticity and flexibility.
It is used for interception of drainage pipes and channels, mainly used in water supply and drainage, civil engineering and fire rescue.
The pipeline blocking airbag complies with the German sewer laying and inspection standard DIN EN1610, and has passed the leak test of new and old pipelines.

Structure of Inflatable Rubber Pipe Test Plug
Pipeline blocking rubber airbag typically has a body of cylindrical shape and two conical heads, one at each end. At each head end, there is a metal bushing as a mouth for air inflation and the plug with a ring.
If customers have special needs, we can also customize according to customer needs
Pipeline Plugging Water Stop Airbag Application
• Urgent repair, overhaul and maintenance of drainage and sewage pipelines
• Sludge treatment
• Closed water and air closed experiment
• Culvert water delivery
The working principle of airbag water blocking is to expand it by inflation. When the gas pressure in the airbag reaches the specified requirements, the airbag fills the entire pipeline section, and the friction force generated by the airbag wall and the pipeline is used to block the water leakage, so as to reach the target pipe section. No seepage purpose.
How to use the pipeline water blocking airbag
Put the pipeline blocking airbag at the pipe opening that needs to be blocked. The length of the pipeline is the length of the airbag, and then the compressed air is injected through the intake valve to the specified pressure, and the construction can be carried out. After the construction is completed, open the intake valve and release it. air, remove the bladder.
