Description

Technical Field

[0001] The utility model relates to the technical field of foam ceramic heat preservation pipelines, and particularly relates to a foam ceramic conveying pipeline for heat preservation. Background Art

[0002] Foam ceramic materials, due to having a large number of uniformly distributed pores inside, effectively reduce the solid part of the material, thereby reducing its heat conduction ability. Specifically, the high porosity makes the heat transfer path in the foam ceramic complex and long, which helps to reduce the heat transfer speed, so it can be used as a good heat preservation layer for heat insulation of liquid conveying pipelines;

[0003] In the prior art, foam ceramics are usually arranged inside steel pipes, and a coating layer is used for separating materials. For example, in the patent with the publication number CN206268715U, the disclosed lightweight heat insulation and heat preservation pipe specifically uses epoxy powder coating as the inner wall coating of the foam ceramic pipe body, and a steel pipe is arranged on the outer wall of the foam ceramic pipe body;

[0004] However, although epoxy powder coating has corrosion resistance and toughness, due to the multi-porous structure of the foam ceramic itself, pores are filled and blocked by fillers during the coating brushing stage, resulting in a reduction in the heat insulation function of the foam ceramic, an increase in weight, and in the actual application process, the uniform brushing of fillers is not easy to operate, which increases the preparation difficulty; in addition, for cases where a certain transportation distance is required, if the internal heat insulation structure cannot be disassembled and transported, it will also cause difficulties in transportation and installation.

[0005] Based on the above description, there is an urgent need for a foam ceramic conveying pipeline for heat preservation that can ensure the heat preservation function of the foam ceramic, is lightweight, and is easy to disassemble and assemble. Summary of the Utility Model
