Dongfeng professional consumption sewage pipe water plugging special price low quality
Sewage pipe water plugging is also called pipe pressure plug, pipe plug, skin plug, gas filled pipe plug, pipe plug, etc., which is called differently according to different people's habits. Sewage pipeline water plugging is mainly used for municipal pipeline leakage plugging, sewage and drainage pipeline detection, pipeline maintenance, natural gas pipeline plugging, inspection port plugging, pipeline maintenance, pipeline water closing test, pipeline water filling test and other projects. Precautions for sewage pipe plugging in operation are as follows
1. The sewage pipe water blockage cannot be contracted to one side when pumping air, and the air pressure cannot be pumped up. If the air continues to inflate, the water blockage will be broken. As for cast iron drainage pipe, it is required to clean the sand, make the inner wall flat, and do not allow burrs, otherwise it will affect the water plugging and sealing, and even puncture the capsule. Various specifications of water plugging must be used in the corresponding pipeline, and cannot replace the big with the small.
2. In order to avoid separation from the rubber hose, the joint with the rubber hose shall be fastened by iron wire or other means.
3. Fill the water at the filling port (or at the inspection port) of the floor to the height of the floor, and then check the filling pipes and pipe fittings one by one. If any leakage is found, make a mark, and stop repairing after drainage; If it is a ring flexible interface, it can be repaired with water tight bolts at the leakage interface. If there is no leakage point in the inspection of the water filling pipeline, the water level can be stabilized, and the water filling time lasts for 15 minutes. If the water filling level does not drop for 5 minutes, it is qualified.
4. The sewage pipe is blocked and deflated, and then the water is slowly pumped out to block the water. Be careful not to damage the water blocking.
5. After the water is taken out, the water should be able to drain away quickly. If the water falls slowly, it should be clarified that there are sundries in the irrigation pipe section, which should be cleared in time.
