In the continuous production of modern industry, the flange is influenced by the factors such as medium corrosion, erosion, temperature, pressure, vibration and so on.
The leakage of Flange is easily caused by the error of machining dimension of sealing surface, aging of sealing element and improper installation and fastening. If the problem of Flange leakage can not be solved in time, the leakage will expand rapidly under the scour of medium, resulting in material loss, production environment damage, leading to enterprise shutdown, resulting in huge economic loss. If it is toxic and harmful, flammable and explosive medium leakage, there may be caused by poisoning, fire and explosion and other major accidents. The traditional method to solve the leakage of flange is to replace the sealing element and Daub the sealant or to replace the Flange and pipeline, but this method has great limitations, and some leakage is limited by the requirement of working environment safety, can Not be solved on the spot. The polymer composite material can be used to plug the leak in the field, in which the more mature system of fossblue is used. It is a very ideal method, especially in inflammable and explosive situations, but also shows its unique advantages. Polymer composite technology is simple, safe and low cost. It can solve most problems of flange leakage, eliminate hidden trouble and save more maintenance cost for enterprises.
