The product principle
These inflatable pipe stoppers consists of aluminum foil composite material, that means to use the theory of inflation for the sake of plugging the mouth of pipe. There are waterproof adhesive on both sides of the inflatable pipe stoppers.When waterproof adhesive to inflate air pressure weighs 2.6-2.8 kilogs,it will fill the space among pipeline, inflatable pipe stoppers and electrical conduit ,so that it can get totally stealing.If had inflation done and gas valve pulled out,the silica gel material installed on inflatable hole inside of inflatable pipe stoppers,it can depending on performance of self-padding allows tight shutoff immediately to prevent air leakage efficiently.

Applied Range
1.Suited to waterproofing and sealing of pipeline in various industry(as electricity,communication, urban construction).
2.Mainly applied to pipe orifice sealing of cable conduit underground, hole penetrated wall sealing of wall body in civil engineering.
3.Adequate for pipeline in different solid materials like plastic,steel, concrete etc.
4.Sealing holes only limited to circular shape or the oval shape.

Feature and strongpoint of products
1.Installed fleely,uninstalled succinctly,do not to damage cable conduit
and pipeline;
2.Low cost construction,no need for supports from water and power sources,dispense with traditional tools for project.
3.Sealing effectively,can prevent substances (as seeper,silt,insects and mice,harmful gas etc.) from going into the pipelines;
4.Extraordinary long time for sealing efficiently,saving cost for maintenance at the late stage extremely;
5.Installed spare suction pipe,single-cable pipe orifice,multi-cable pipe orifice availably;
6.Shift of the cable in small extent acceptably and also have a certain ability for earthquake-resistance;
7.Not influenced by acid and alkaline circumstances,water circulation of pipelines;  
8.After sealed network of pipes by segmenting,shorten or even avoid pumping water and dredging before rush repair and maintenance job making it more efficient exceedingly.

Using effect of products
1 No longer the circumstance of cable operating will influenced by substances (as seeper,silt,insects and mice,harmful gas etc.),improved its security markedly;
2 Meliorated working conditions in artificial-well,pipe drain underground,basement of transformer substation,terminal cable hut etc. to enhance working efficiency.
