In the continuous production of modern industry, the flange is affected by medium corrosion, erosion, temperature, pressure, vibration and other factors, and the leakage problem will inevitably occur. Due to the error of the processing size of the sealing surface, the aging of the sealing element and the improper installation and fastening, it is easy to cause the leakage of the flange. If the flange leakage problem cannot be treated in time, the leakage will expand rapidly under the erosion of the medium, resulting in the loss of materials, the destruction of the production environment, the shutdown of the enterprise, and the huge economic loss. If it is a leakage of toxic, harmful, flammable and explosive media, it may also cause major accidents such as personnel poisoning, fire and explosion.
The traditional method of solving flange leakage is to replace the sealing element and apply sealant or replace the flange and pipeline, 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. Now polymer composite materials can be used for on-site plugging, among which the application of the more mature Fushi blue system. It is an ideal method, especially in flammable and explosive situations, and shows its unique advantages. The construction process of polymer composite technology is simple, safe and low-cost, which can solve most of the flange leakage problems for enterprises, eliminate potential safety hazards, and save more maintenance costs for enterprises.
