In the continuous production of modern industry, PL Flange products are affected by medium corrosion, erosion, temperature, pressure, vibration and other factors, and leakage problems will inevitably occur. The leakage of PL Flange products is easily caused by the error of the machining dimension of the sealing surface, the aging of the sealing element and improper installation and fastening. If the leakage of PL Flange products cannot be dealt with in time, the leakage will expand rapidly under the scouring of the medium, resulting in the loss of materials, the destruction of the production environment, and the shutdown of the enterprise, resulting in huge economic losses. Leakage of toxic, harmful, flammable and explosive media may also cause major accidents such as personnel poisoning, fire and explosion.

The traditional method to solve the leakage of PL Flange products is to replace the sealing element and apply sealant or replace the PL Flange products and pipes, but this method has great limitations, and some leakage is limited by the safety requirements of the working environment and cannot be repaired on site. to solve. The construction process of polymer composite material technology is simple, safe, and low in cost. It can solve most of the leakage problems of PL Flange products for enterprises, eliminate potential safety hazards, and save more maintenance costs for enterprises.
