In the process of chemical production, pipeline system is an important way of material transportation. However, due to the varying temperature of the conveying medium, in order to ensure the stability of the process, reduce heat loss and ensure the safety of operation, it is particularly important to carry out effective thermal insulation treatment of the pipeline. Choosing the right insulation material can not only improve energy efficiency, but also extend the service life of the equipment.
