Plug the leak
In the upstream and downstream sections of the cleaning area, rubber bladders are installed to seal off, cutting off all water sources, controlling the corresponding water levels, reducing bladder pressure, and enhancing operational safety. Attention must be paid to the bladder sealing process: the lower bladder must be positioned at the lower mouth of the upstream wellhead of the section to be cleaned and at the upper mouth of the downstream wellhead, as shown in the attached table.1. Regularly check the airbag pressure gauge for any signs of pressure loss and promptly replenish as needed. Refer to Appendix 2 for airbag parameters and operating range.
