Online leak sealing techniques are used in many ways, a lot of leakage occurred in the system, can use such technologies to do patch processing, to ensure to solve leakage problems, to achieve reliable sealing effect. But homework a lot of specific methods, using different methods, in terms of operation in different pan from facts. For instance in such operations to eliminate the leakage of flange sealing surface when everybody should do:

　　Online leak sealing to eliminate leakage of flange sealing surface, you must first check the flange bolts in good condition, require that the severe corrosion bolt all replacement. Change the operation of the bolt must be changing the rules of the bolt. Then pay attention to all the injection valve, drain valve open, with smooth discharge medium leakage, reduce the injection pressure. Also, pay attention to the injection of sealant should be carried out several times, in order by the leak is the most distant point injection into the sealant, and gradually shift to leak point near the injection point, know the last block.

　　There are very important, is to be strictly controlled in the online leak sealing injection pressure, the initial injection pressure should not be greater than 6 MPa, the last point injection pressure should not be greater than 10 MPa, the leak leakage point system is more than 10 MPa, injection pressure increasing, but the maximum injection pressure leakage is not greater than the system pressure + 10 MPa.
