Common Faults of Flanges


As the threaded flange is cast, the liquid metal will fill the mold while rotating and solidifying. Flange castings have the following characteristics: Liquid metal can form a freely selected hollow cylindrical surface in the mold, so that hollow castings can be cast without a core, which greatly simplifies the production and management of casing and pipe fittings. It can greatly simplify the casting process, improve production efficiency, and reduce costs.

Due to the flange force, the filling conditions are improved, and the gas and non-metallic inclusions are easily discharged from the liquid or metal. Flange castings have dense structure, fewer shrinkage holes, pores, inclusions and other defects, better mechanical properties, eliminate or greatly save metal consumption in pouring and risers, and have high utilization of metal equipment. Due to the liquid Flange force generated by metal, the use of blue casting 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 leakage problem cannot be solved in time, the leakage will rapidly expand under the erosion of the medium, causing material loss, destroying the production environment, causing the company to stop production, and causing huge economic losses. If the main accident is the leakage of toxic, flammable, and explosive media, it may also cause poisoning, fire, or explosion. Corrosion is the inevitable leakage of continuous production flanges in the modern industry, corrosive media, temperature, pressure, vibration, and other factors. Due to the size error of the sealing surface, the aging of the sealing element, improper installation, and tightening, flange leakage is easy to occur.

In some traditional enterprises, the solution to flange leakage is to replace sealing elements and apply sealant, or replace Stainless Steel Flange wholesale and pipes. However, the research on this method has great limitations. Some leaks will be affected by the safety of the work and living environment. To limit, eliminate safety hazards, and save more maintenance costs for enterprises, we can now use polymer composite plugging solutions, which have very ideal methods, especially inflammable and explosive environments. Unique polymer composite technology has the advantages of the simple construction process, safety, and low cost.

The same is true for large flange connections. The real significance of using flanges is that they have good sealing performance, and can effectively protect the smoothness and tightness of the entire pipeline. It can not only improve the effective sealing effect of the enterprise but also can be effectively disassembled and assembled. Of course, for the second use and cleaning, flanges are unusual products, divided into pressure levels, different pipeline pressures, matching equipment or containers, matching materials, and pipe joints, but flanges are also essential in engineering The accessories play an extraordinary role.
