300DN High Pressure Rubber Pipe Plug for Municipal Plumbing Maintenance

300DN Pipeline Water Municipal Plumbing Maintenance Pipe Sealing Airbags

The 300DN pipeline water and municipal pipeline airbag developed and produced by Qingdao Henger Rubber Airbag is made of high-quality rubber. The air bag is blocked due to inflation. When the gas pressure in the water blocking air bag reaches the requirement, the water blocking air bag fills the entire pipeline section, and the leakage is blocked by the friction between the air bag wall and the pipeline, so as to achieve the goal of partially filling the pipeline. The gas expansion can quickly block the water flow and achieve the purpose of impermeability.

300DN pipeline water municipal pipeline airbag airbag is divided into the following raw materials:

(1) Pure rubber type: made of natural rubber, nitrile rubber, neoprene rubber, butyl rubber, etc., made of pure rubber.
(2) Compound rubber: a product processed from a variety of synthetic rubber or natural rubber.
(3) Skeleton material: It is made of rubber or other materials on the surface of polyester, nylon, nylon or aramid fiber fabrics.

Among them, the use scenarios of the 300DN pipeline water and municipal pipeline sealing airbag are: before the pipeline operation, measure the diameter of the sealing tube; hold the side of the inflatable rubber tube plug with the air plug, and slowly put the inflatable rubber tube plug into the pipeline. Before inflating the inflation rubber tube plug, insert it fully into the tube, connect the barometer and pump, and slowly open the valve of the pressure control gauge. Air pressure is controlled within a safe area outside the pressure marked in red. Tighten the steel wire rope to bind the solid sleepers, and observe the data through the pressure control gauge. When the specified requirements are met, close the pressure control valve and the inflation is over. After that, within 20 minutes, keep the pressure control gauge connected to the pipeline, observe the air pressure seal change data, if everything is normal,

Pipe plugs with rubber bags have been used in pipes and culverts to drain sewage and waste water. Also used for repairing rubber appliances. Due to its various sizes, it can be used to block fluids in a variety of situations.
