Description

Technical Field

[0001] The utility model relates to the technical field of protective sleeve equipment, in particular to an installation structure of a galvanized electric heating protective sleeve. Background Art

[0002] Galvanizing is a surface treatment technology that coats metals, alloys or other materials with a layer of zinc. Its main purpose is to enhance the corrosion resistance, aesthetics and mechanical properties of the material. It can be mainly divided into two categories: hot-dip galvanizing and cold-dip galvanizing. Hot-dip galvanizing involves immersing base materials such as steel in molten zinc liquid. Through physical and chemical processes such as immersion and diffusion, a firmly adhered metallic zinc coating is formed on the surface of the base material. It is widely used in construction, transportation, electricity, machinery and other fields, such as galvanized steel plates, galvanized pipes, galvanized components, etc.

[0003] Hot-dip galvanizing can significantly improve the corrosion resistance and service life of metal components. Existing ones usually use sleeves to place heating tubes to maintain the temperature in the boiler. Some sleeves are straight-cylinder type, which are fixed by the gap between steel pipes and swing with the fluctuation of zinc liquid. They have a short service life and are not convenient for disassembly, maintenance and replacement, which increases the difficulty of operation. At the same time, most existing internal heating protection sleeves are made of silicon carbide as the main material. Their production and processing technology is cumbersome, the yield is low, the wall is thick and the thermal conductivity is not high, which makes the heat conversion rate of electricity very low. There are defects such as short service life, high galvanizing production cost, and difficulty in replacement. Utility Model Content
