Common Faults Of Flanges

In the continuous production of modern industry, flanges are affected by factors such as medium corrosion, scouring, temperature, pressure, vibration, etc., and leakage problems will inevitably occur. Due to the error of the sealing surface processing size, the aging of the sealing element and the improper installation and tightening, the flange is very likely to leak. If the flange leakage problem cannot be solved in time, the leakage will expand rapidly under the scouring of the medium, causing material loss, damage to the production environment, and cause the company to shut down and stop production, resulting in huge economic losses. If the toxic, harmful, flammable and explosive medium leaks, it may also cause major accidents such as poisoning, fire and explosion.
The traditional method to solve flange leakage is to replace the sealing element and apply sealant or replace the flange and pipeline, but this method has great limitations, and some leakage is limited by the requirements of the working environment safety and cannot be solved on site. Now polymer composite materials can be used for on-site plugging, among which the more mature application is the Fushilan system. It is an ideal method, especially in flammable and explosive occasions, and it shows its unique superiority. The construction process of polymer composite material technology is simple, safe and low-cost. It can solve most flange leakage problems for enterprises, eliminate safety hazards and save more maintenance costs for enterprises.
