Product Name: Pipe sealing bag Brand: Kang Bridge Color: Black Material: Natural rubber thickness index: 3mm above specifications: Round conventional + can be customized temperature: -40-60 degrees inflation pressure: 0.026-0.042mpa elastic index : no stretch micro-bomb elastic super bomb Accessories: Tee gauge, certification, factory inspection report duct sealing bag (pipe sealing bag price) Inflatable rubber plug (cheap) use should note the following one First check the parts are tight connection, pressure gauge pointer is pointing to zero, pipe sealing balloon inflated swing is normal, if found to have abnormal pressure gauge pointer swings, should be replaced with new gauges, the accessory connected with the airbag After first open state to inflate the airbag test, test inflation pressure must not exceed 0.01mpa, airbags and connections with soapy water to check for leaks accessories. Second, before use, should check the basic situation inside the pipe, the pipe should be checked for new pipe wall is smooth, whether there is mud, whether precipitation projections whether the cement residue inside the old pipe sludge, broken glass, sharp solid objects, etc., pipeline cleaning is not clean cause blocking effect is reduced, resulting in local leakage, particularly when used in cast iron pipes and cement pipes should pay special attention to prevent the airbag inflator after sealing balloon punctured pipeline. Third, the pipe sealing bag in the pipe has a status of debris inside the pipe is not good judgment when water operations, in addition to cleaning up the pipe, then add a protective response surface of the balloon, such as surface put a canvas cover, or not low to 4 mm rubber pad for an air bag plus one parcel, otherwise, the balloon in the water can easily be punctured some of the debris. Fourth, in the operation to block the sewage pipe, the pipe sealing bag in the pipe work time should be shortened, preferably not more than 12 hours, often contain chemical wastewater typically some organic or inorganic solvent, a long soak or the balloon surface corrosion emulsifying conjunctiva reduce its strength, friction is reduced, the impact block construction. Five pipe sealing bag into the pipeline should be placed parallel to avoid curl, resulting in inflated folded when the airbag to prevent excessive pressure caused by local untapped, airbags discontinuity, the instantaneous boost local cause burst . Six, inflatable pneumatic equipment should be slow-charged, supercharged and in stages, pressure for some time, should be spaced a few minutes to adapt to changes in air pressure inside the balloon, when used for less than DN600 diameter, it is preferable Use small or micro inflatable device to inflate the airbag with a large inflatable devices such inflatable airbag inflator is not easy to grasp the speed, it will cause the balloon inside the chain structure in the absence of further stretch the elastic moment when it was destroyed causing rupture . Seven, the main role is to pipe sealing bag sealing action, when it comes to water pressure is slightly larger than the inflation pressure pipeline deal airbag artificial reinforcement measures include: 1, the front airbag when plugging in the balloon back to put some sandbags to prevent the air bag 2 moves in the pipe, made of a cross erected by mugang shore pipeline wall to prevent the air bag sliding. 3, when the airbag reverse shutoff applications like architectural grille mesh wrapped around the balloon made a string bag like to live with a rope and then construction. Eight, when the pressure inside the pipe sealing bag drop gauge pointer will decline, should promptly fill pressure
