In the continuous production of modern industry, the flange is affected by medium corrosion, scour, temperature, pressure, vibration and other factors, and the leakage problem will inevitably occur. Due to the size of the sealing surface error, the aging of the sealing element and improper installation and so on, it is very easy to cause leakage of the flange. If the leakage of the flange can not be timely treatment, under the medium scouring will cause rapid expansion of leakage, resulting in the loss of materials, production environment damage, resulting in enterprise downtime, resulting in huge economic losses. If it is poisonous and harmful, flammable and explosive media leakage, but also may cause the personnel poisoning, fire explosion and other major accidents.
The traditional method of resolving flange leakage is to replace the sealing element and apply sealant or replace the flange and pipe, but the method has great limitations, and some leakage is restricted by the safety of working environment, and can not be solved on the spot. Polymer composite materials can be used for on-site plugging, in which the application of a more mature system of the blessing of the world Blue. It is an ideal method, especially in flammable and explosive occasions, show its unique advantages. The technology of polymer composite material is simple, safe and low cost, which can solve most of the problem of flange leakage, eliminate the hidden danger and save more maintenance cost for enterprises.
