In the continuous production of modern industry, the influence of factors such as medium corrosion, erosion, temperature, pressure and vibration will cause inevitable leakage. Due to the error in the size of the sealing surface, the aging of the sealing element, improper installation and fastening, etc., it is easy to cause leakage of the flange. If the problem of leakage of the flange cannot be solved in time, under the scouring of the medium, the leakage will rapidly expand, causing the loss of materials and the destruction of the production environment, resulting in the shutdown of the enterprise, causing great economic losses. If it is a toxic, hazardous, inflammable and explosive medium, it may cause serious accidents such as poisoning, fire and explosion.
The traditional way to solve the flange leakage is to replace the sealing components and apply sealant or replace flanges and pipes. However, this method has a lot of limitations, and some of the leakage is limited by the requirements of the working environment and cannot be solved in the field. . Polymeric composite materials can now be used for on-site plugging, in which a more mature system with bluish blue is applied. It is a very ideal method, especially in flammable and explosive situations, showing its unique advantages. The technology of polymer composite materials construction is simple, safe, and cost-effective. It can solve most of the flange leakage problems for enterprises, eliminate potential safety hazards, and save more maintenance costs for enterprises.
