Common faults of flange

　　In the continuous production of modern industry, flange is affected by medium corrosion, erosion, temperature, pressure, vibration and other factors, which will inevitably lead to leakage.

　　It is easy to cause flange leakage due to the processing dimension error of sealing surface, aging of sealing elements and improper installation and fastening. If the problem of flange leakage can not be solved 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, leading to the shutdown of the enterprise, resulting in huge economic losses. If it is toxic, harmful, flammable and explosive medium leakage, it may also cause personnel poisoning, fire and explosion and other major accidents.

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