Summary of problems and solutions encountered during flange processing

Due to the function of flange processing, the filling conditions are improved, and gases and non-metallic inclusions are easily discharged from the liquid or metal. The flange processing structure is dense, with fewer defects such as shrinkage, pores, and inclusions, and good mechanical performance. It eliminates or greatly saves metal consumption in casting and riser, and has a high utilization rate of metal equipment. Because the liquid rotates in different ways to generate flange force on the metal, the flange processing technology can improve the filling capacity of the metal, so the flange casting method can be used to produce alloys and thin-wall castings with poor Social mobility.
If the flange processing leakage problem cannot be solved in a timely manner, the leakage will rapidly expand under the erosion of the medium, causing material losses, damaging the production environment, causing the enterprise to stop production, and causing huge economic losses. If the main accident is the leakage of toxic, flammable, and explosive media, it may also lead to poisoning, fire, or explosion. Corrosion is an inevitable leakage of flange plates in modern industrial continuous production and processing, as well as factors such as corrosive media, temperature, pressure, and vibration. Due to dimensional errors in the sealing surface, aging of sealing components, incorrect installation and tightening, flange leakage is prone to occur.
In some traditional enterprises, the solution to flange processing leakage is to replace sealing components and use sealant, or replace flanges and pipelines. However, this method of research has significant limitations. Some leaks will be affected by the safety of the work and living environment. In order to limit, eliminate safety hazards, and save more maintenance costs for enterprises, we can now use polymer composite material plugging solutions, which have very ideal methods, especially in flammable and explosive environments. The unique polymer composite technology has the advantages of simple construction process, safety, and low cost.
The same applies to large flange connections. The true significance of using flanges lies in their excellent sealing performance, which can effectively protect the smoothness and sealing of the entire pipeline. It can not only improve the effective sealing effect of enterprises, but also effectively disassemble and assemble them. Of course, for secondary use and cleaning, flanges are unusual products, classified into pressure levels, different pipeline pressures, matching equipment or containers, matching materials and pipe joints. It is important to know that essential accessories play an extraordinary role.
