Application of Enamel Frit in Air Preheater Pipes

Corrosion Resistance Effect Is Astonishing To Enamel Manufacturers

Recently, Nolifrit's technical team proofed a batch of enamel samples for air preheating pipes. Its smooth and clean surface and high corrosion resistance have been highly recognized and appreciated by customers. The enamel manufacturer expressed great satisfaction with the excellent performance of the samples and expressed strong interest in further cooperation.

Air preheating pipes have been worn by fly ash for a long time, especially some air preheating pipes made of poor materials. If the corrosion resistance and wear resistance are poor, it is more likely to shorten the service life and increase maintenance costs. In order to solve this problem, enamel frit is widely used on the inner wall of pipes to achieve good corrosion resistance.

Air preheater pipes are an important part of many large industrial boilers. Their operating temperatures are usually above 150°C, which places high requirements on the materials and coatings of the inner walls of the pipes. As a glassy composite inorganic material, enamel frit is widely used in the transportation and storage of industrial media because of its extremely high chemical stability and corrosion resistance, especially against acid, alkali and salt corrosion. Resistance. Therefore, enamel frit applied to the inner wall of air preheater pipes can provide good corrosion resistance and service life.

enamel frit has strong adhesion properties and can be firmly attached to the inner wall of the pipe to form a flat and smooth surface without hindering the flow of gas. In addition, enamel frit also has good thermal conductivity, which can effectively increase the heat transfer efficiency of the inner wall of the pipe and improve the thermal efficiency of the air preheater.

In practical applications, enamel frits as inner wall materials can effectively increase the service life and maintenance cycle of air preheater pipes, and reduce the maintenance costs of enterprises. At the same time, because the enamel frit has high chemical stability, it can avoid corrosion and rust on the inner wall of the pipeline, ensuring safety and stability in production.

In short, the application of enamel frit as the inner wall material of air preheater pipes has broad prospects. Choosing high-quality enamel frit can make the air preheater pipe have better corrosion resistance and heat transfer efficiency under high temperature and high pressure, providing more reliable guarantee for industrial production.
