In the continuous production of modern industry, flanges are susceptible to medium corrosion, erosion, temperature, pressure, shock. The influence of factors such as movement will inevitably lead to leakage problems. Due to the processing size of the sealing surface error, the aging of the sealing element and improper installation and other reasons are very likely to cause flange leakage. If the flange leakage problem cannot be controlled in time, the leakage will be rapid under the erosion of the medium. Expansion leads to the loss of materials and the destruction of the production environment and huge economic loss. If it is a poisonous and harmful, flammable and explosive medium leaking, it may also cause major accidents such as personnel poisoning, fire and explosion.
The traditional solution to flange leakage is to replace the sealing element and apply sealant or replace the flanges and pipes, but this method has great limitations, and some leaks are subject to the safety of the industrial environment. The requirements are limited and cannot be resolved on site. Polymer composite materials can now be used for on-site Leakage prevention, in which the relatively mature Blessed Blue system is applied. One of the ideal methods, especially in flammable and explosive occasions, also shows its unique advantages, polymer composites material technology construction process is simple, safe, and low cost, can solve most of the flange leakage problem for enterprises, in addition to hidden safety hazards, saves enterprises more maintenance costs.
