Common faults of flanges In the continuous consumption of modern industry, flanges are affected by factors such as medium corrosion, erosion, temperature, pressure, vibration, etc., which will inevitably lead to leakage. Due to the dimensional error of the seal surface processing, the aging of the sealing element, and the improper installation and tightening, flange leakage is likely 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 loss of data 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 way to deal 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 handled 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 has solved most of the flange leakage problems, eliminated safety hazards, and saved more maintenance costs for the company.
