[0002] Pipeline insulation is a protective technology to prevent condensation or freezing of the medium transported by the pipeline. For general oil (gas) pipelines, the most common method is to add an insulation layer to the outside of the pipeline. The insulation layer is pressed and formed with closed-cell rigid polyurethane foam plastic and protected by a skin. However, for pipelines transporting highly viscous and easily condensed crude oil, steam or hot water coils must be added for insulation. It is more troublesome to install insulation devices at the elbows of the pipeline, so easy-to-install elbow insulation jackets are required.
