Inflatable Rubber Pipe Stoppers

These Inflatable Rubber Pipe Stoppers are used in leaking hunting for drainage pipeline. The Inflatable Rubber Pipe Stopper is made of high quality polymer materials and because of good gas tightness and light weight; Inflatable Rubber Pipe Stopper could be used in all kinds of non-pressure and low tension pipeline.
Usage method of Inflatable Rubber Pipe Stopper:
Before operation of pipeline work of flow condition, measure the diameter of the sealing pipe; Hold on the side of the Inflatable Rubber Pipe Stopper with air cock, slowly put the Inflatable Rubber Pipe Stopper into pipes. Before inflate the Inflatable Rubber Pipe Stopper, insert it completely in pipe, and connect the barometer and pump, then opened slowly the valve of pressure control table. The air pressure is controlled in safety area outside of pressure marked red. Taut drawing rope in sleepers on rope binding firm, through pressure control list, observation data, while it reaches the formulary requirement, close the vales of pressure control, and inflating is end. After that, within 20 minutes, keep connection between pressure control tables and pipe, observe data of air pressure sealing variation, if everything is normal, and then starts
