In the continuous production of modern industry,
flanges will inevitably leak due to the influence of temperature, pressure, vibration and other factors. Due to the error of the processing size of the sealing surface, the aging of the sealing element and the improper installation and tightening, it is easy to cause the leakage of flanges. If the
flange leakage problem cannot be solved in time, the leakage will rapidly expand under the scouring of the medium, resulting in the loss of materials and the destruction of the production environment, which will lead to the shutdown of the enterprise and cause huge economic losses. If the leakage of toxic, harmful, flammable and explosive media may cause serious accidents such as personnel poisoning, fire and explosion, etc.
The traditional method to solve flange leakage is to replace sealing elements and apply sealant or replace flanges and pipes, but this method has great limitations, and some leakage is limited by the safety requirements of the working environment and cannot be solved on site. Polymer composite materials can now be used for on-site leakage plugging, which is an ideal method, especially in flammable and explosive occasions, which shows its unique advantages. The construction process of polymer composite material technology is simple, safe, and low cost. It can solve most of the flange leakage problems for enterprises, eliminate potential safety hazards, and save more maintenance costs for enterprises.
