Insulated steel pipes, also known as heat preservation pipes, are steel pipes that have undergone heat insulation processing. They ensure that the internal temperature of the working pipe meets or reaches the required temperature in various operating environments and under the influence of external media.

Insulated pipelines are widely used in the transportation networks for liquids and gases, in projects such as petrochemical pipeline insulation, centralized heating networks, central air conditioning ventilation pipelines, and municipal engineering.
