The flange is a connecting part between the shaft and the shaft, used for the connection between the ends of the pipe. In the continuous production of modern industry, the flange will be unavoidably leaked because of the influence of medium corrosion, erosion, temperature, pressure and vibration.
Because of the sealing surface processing error, sealing components aging and installation, improper fastening and other reasons, it is easy to cause flange leakage.
The solution to flange leakage is to replace sealing elements and apply sealant or to replace flanges and pipes. However, this method has great limitations, and some leaks are limited by the safety requirements of the working environment and can not be solved on-site. Polymer composite materials can be used for on-site plugging, and this method shows its unique advantages.
