How is the flange of rubber expansion joint maintained?

If the rubber soft joint is bought back to be stored, it should be placed in a place where the sun does not shine or in a cool and dry place, avoid strong acid and alkaline things, and also apply a layer of talcum powder on the appearance of the rubber joint. If in the open field, wrap it with a plastic bag. This will provide good protection for the flange. If it is not maintained or replaced in time for a long time, flange leakage may occur, and under the washout of the medium will make the leakage expand rapidly, causing huge economic losses. The method of flange leakage is to replace the sealing components and apply sealant or replace the flange and pipe, but the method has great limitations, and some leakage is restricted by the requirements of the safety of the working environment and cannot be solved on site. Now it is possible to use polymer composite materials for on-site plugging, of which the application is more mature with the system of Fushi Blue. It is a very ideal method, especially in flammable and explosive occasions, but also to show its unique superiority. The construction process of polymer composite material technology is simple, safe and low cost, which can solve most of the flange leakage problems for enterprises, eliminate safety hazards and save more maintenance costs for enterprises.
