Enamel tube air preheater
Thread Content
Dear masters, what kind of tube is the enamel tube air preheater? Please give me a detailed introduction.
Are there any requirements for processing, just the welds of enamel pipes?
The outside of the welded pipe is enamel-plated, and the welding part between the pipe mouth and the tube plate is not enamel, and castable is generally used.
Enamel pipe is a layer of enamel coated on the surface of seamed steel pipe. Due to the addition of enamel material, the heat transfer effect is different from that of metal steel pipes, and welding cannot be performed. The seal between the pipe and the tube sheet will leak after a period of operation, which requires brainstorming to solve.
Could you please introduce your company's advanced experience? Thank you!
