Description

Technical Field

[0001] The utility model belongs to the technical field of corrosion-resistant insulating pipe sleeves, and relates to an insulating pipe sleeve with a corrosion-resistant structure. Background Technique

[0002] The disadvantages of existing insulating pipe sleeves in terms of corrosion resistance and insulation are mainly reflected in material aging and decline in physical properties. The reasons for these disadvantages are usually related to the chemical composition of the material itself and the harshness of the use environment. For example, when some polymer materials used in insulating pipe sleeves are exposed to ultraviolet rays, high temperatures, humidity, or chemical substances for a long time, molecular chain breakage, cross-linking, or oxidation reactions will occur, resulting in material performance degradation.

[0003] Conventional countermeasures include using materials with stronger corrosion resistance, increasing the thickness of the pipe sleeve, coating a protective layer, or using a protective coating, etc. Although these methods can improve the corrosion resistance of the insulating pipe sleeve to a certain extent, they also have some drawbacks. For example, using more corrosion-resistant materials may lead to a significant increase in cost, and not all corrosion-resistant materials have good insulation performance. Therefore, there is an urgent need for an insulating pipe sleeve with a corrosion-resistant structure to solve the above problems. Content of the Utility Model
