Common problems of socket flanges

　In the continuous production of modern industry, the socket flange will inevitably leak because of the influence of medium corrosion, erosion, temperature, pressure, vibration and other factors. The leakage of socket flange is easily caused by the error of machining dimension of sealing surface, aging of sealing element and improper installation and fastening. If the GOST 12821-80 PN40 Stainless Steel Socket Flange leakage problem can not be solved in time, the leakage will expand rapidly under the medium erosion, resulting in material loss, production environment damage, resulting in the shutdown of enterprises, resulting in huge economic losses. If it is toxic and harmful, flammable and explosive media leakage, it may also cause personnel poisoning, fire and explosion and other major accidents.

　　The traditional method to solve socket flange leakage is to replace sealing elements and apply sealant or replace socket flange and pipes, but this method has great limitations, and some leakage is limited by the safety requirements of the working environment, can not be solved on the spot. Polymer composites can be used to plug the leak in the field, among which Fushi Blue system is more mature. It is a very ideal method, especially in inflammable and explosive occasions, but also shows its unique advantages. The construction technology of polymer composite material is simple, safe and low cost. It can solve most of the problems of socket flange leakage, eliminate hidden dangers and save more maintenance costs for enterprises.
