What problems need to pay attention to when inflating the pipe?
The charging pressure does not exceed the working pressure of the air sac, and the sharp object is prevented from scratching the gasbag during the inflating process
Pipe water blocking airbag, closed water test, sewage pipe matters are different, big air sac, small sac also have differences, in terms of sewage pipes, we need to pay attention to the following points:1, because the airbag is rubber products, so afraid of scratching, when receiving airbags, we must first test gas test to see if there are broken places. Repair and replace in time.2, carefully check instructions, rated pressure, etc..3, in the ground to connect three pressure gauge, slowly filling some gas, slowly into the pipeline.4, clean up the pipeline wall, no burr, punctured balloon.5, carefully checking the pressure meter, slow inflation, do not look at the gas, to avoid pressure gauge not timely response and the consequences of explosive charge. When the work pressure is up, stop inflating and never exceed the pressure.6. The large air bag has a handle on it and prevents it from running.
Rubber pipeline plugging bag should keep the inner pressure of the gasbag is uniform when inflated, inflated slowly rising inflation, observe the pressure gauge without change, such as pressure gauge shows rapid rise in inflation is too fast, the inflation rate should slow down, stop valve will tighten slightly, reduce the inlet velocity, or the speed is too fast, faster than pressure is likely to break into the rubber balloon. - Zhang
