Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal pipelines, and more specifically, to a thermal pipeline insulation device. Background Art
[0002] Thermal pipelines are pipelines that transport thermal energy media such as steam or superheated water. Thermal pipelines are characterized by high temperature, high pressure, and fast flow rate of the medium they transport, which will bring greater expansion and impact forces to the pipeline during operation. Therefore, during pipeline installation, issues such as pipeline material, pipeline expansion compensation, pipeline supports and hangers, pipeline slope, and drainage and venting devices should be addressed to ensure the safe operation of the pipeline.
