Abstract
Description
Technical Field
[0001] This patent relates to the field of thermal insulation technology, specifically to the compensation structure of a steam overhead thermal insulation pipe compensator. Background Technology
[0002] Steam can transport heat energy through pipelines to areas with a radius of several kilometers or even twenty kilometers. During long-distance transportation, heat loss is inevitable. To reduce heat loss during transportation, the pipelines and fittings used for transporting steam must be insulated. In the early days, when steam transportation distances were short, the proportion of heat loss during transportation was not large.
[0003] In northern cities, daily winter heating is provided by hot gas or hot water, and most of the pipelines are directly buried. To ensure the steam pressure in the steam pipelines, improving the overall insulation performance of the steam pipelines is crucial. Expansion joints are installed at intervals along the steam pipelines to accommodate expansion and contraction. However, the existing expansion joints are quite heavy, and without proper support, the pipe joints may break over time, leading to loosening and leaks, which affects usability. Therefore, improvements to the existing technology are necessary. Utility Model Content
