The previous life of the pipe blockage [PRONAL]
One, brief introduction of pipe plugging air bag, the pipe plugging air bag is called closed water plugging, pipe plugging air bag, pipe blocking device, closed water test airbag, closed air test air bag。 The pipe plugging air bag is made of reinforced natural rubber。 Each water shutoff air bag is tested under 1。5 times rated working pressure and the corresponding type of pipe diameter before delivery。 In order to ensure the strength of the airbag structure is blocked, we use a safety factor of three times the rated working pressure of the pipe seal。
Two, the specifications of the pipe plugging air bag edit the pipe plugging air bag (closed water plugging, pipe blocking air bag, pipe sealing device, closed water test air bag, closed air test air bag) type include: PVC gas nozzle capsule, compound closed water shutoff, air nozzle closed water plug, double inflatable capsule.
Three。 Performance characteristics of pipe plugging air bag
1, operate intuitively and directly observe pressure operation of pressure gauge, and inflate according to standard pressure.
2, the size of the body is small, and it is easy to plug into the pipeline, which is economical and practical。
3, the air bag can bend 180 degrees freely, and has a certain corrosion resistance。
4, made of reinforced natural rubber, super expansibility。
Four. The construction method of the pipe plugging air bag is to edit the water shutoff of the pipe plugging air bag. The principle of the operation is to inflate the air bag made of high quality rubber. When the gas pressure in the water shutoff air bag reaches the required requirements, the water shutoff air bag fills the whole canal section and plugging he air bag wall and pipe by the pipe. The frictional force generated by the road blocks the leakage so as to achieve the purpose of no seepage in the target pipe section.
