Common faults of flange

　　In the continuous production of modern industry, flange leakage will inevitably occur due to the influence of medium corrosion, scouring, temperature, pressure, vibration and other factors. Due to the error of processing size of sealing surface, aging of sealing elements and improper installation and fastening, it is very easy to cause flange leakage. If the flange leakage problem cannot be solved in time, the leakage will expand rapidly under the scouring of the medium, resulting in the loss of materials and the destruction of the production environment, leading to the shutdown of the enterprise and huge economic losses. If it is toxic, harmful, flammable and explosive medium leakage, it may also cause major accidents such as personnel poisoning, fire and explosion.

　　The traditional methods to solve flange leakage are to replace sealing elements, apply sealant or replace flanges and pipes, but this method has great limitations, and some leakage can not be solved on site due to the requirements of working environment safety. Polymer composites can now be used for on-site plugging, in which the more mature youfushi blue system is applied. It is a very ideal method, especially in flammable and explosive occasions, which shows its unique advantages. Polymer composite technology has the advantages of simple construction process, safety and low cost. It can solve most flange leakage problems for enterprises, eliminate potential safety hazards and save maintenance costs for enterprises.
