Insulated steel pipes are steel pipelines that, after undergoing heat preservation processing, ensure that the internal temperature of the working pipe meets or reaches the required usage temperature, even under varying working environments and the influence of external media.

Insulation pipes are widely used in pipeline networks for the transportation of liquids and gases, including in petrochemical and chemical industry insulation projects, oil and chemical pipelines, centralized heating networks, central air conditioning ventilation pipes, and municipal engineering projects.
