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.
