In the continuous production of modern industry, flanges are affected by media corrosion, erosion, temperature, pressure, vibration and other factors, and leakage problems will inevitably occur. Due to the error in the dimensions of the sealing surface, the aging of the sealing elements and improper installation and tightening can easily cause leakage of the flange. If the flange leakage problem cannot be treated in time, the leakage will rapidly expand under the erosion of the medium, resulting in the loss of materials and the destruction of the production environment, leading to the shutdown of the enterprise and the huge economic loss. If it is a toxic and harmful, flammable and explosive medium leaking, it may also cause major accidents such as poisoning of personnel, fire and explosion.
The traditional method of solving flange leakage is to replace sealing elements and apply sealant or replace flanges and pipes, but this method has great limitations, and some leakages are 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 leak plugging, of which the more mature Blessing Blue system is applied. It is an ideal method, especially in flammable and explosive occasions, and shows its unique superiority. The polymer composite technology construction process is simple, safe, and low in cost. It can solve most flange leakage problems for enterprises, eliminate hidden safety hazards, and save more maintenance costs for enterprises.
