Common faults of flanges In the continuous consumption of modern industry, flanges are affected by factors such as medium corrosion, erosion, temperature, pressure, and vibration, which inevitably lead to leakage. Due to the size error of the seal surface processing, the aging of the sealing element, and the improper installation and tightening, flange leakage is prone to occur.

If the flange leakage problem is not dealt with in time, the leakage will shrink rapidly under the erosion of the medium, resulting in data loss and destruction of the consumer environment, resulting in enterprise shutdown, resulting in huge economic losses; leakage of toxic, harmful, flammable and explosive media may also be possible Serious accidents such as poisoning, fire and explosion have occurred.

　　The traditional method of dealing with flange leakage is to change the sealing element and apply sealant, or change the flange and pipeline, but this method has great limitations. Some leakage is restricted by the safety of the working environment and cannot be dealt with on the spot. At present, polymer composite materials are mainly used for on-site leak plugging, and the more mature system is blue.

　　 It is an ideal method, especially in flammable and explosive conditions, but also shows its common advantages. The polymer composite process is simple, safe, and low in cost. It solves most of the flange leakage problems, eliminates safety hazards, and saves more maintenance costs for the company.
