What are the advantages of anti-corrosion and insulated steel pipes?

The insulation material used in general insulation steel pipes is mostly rigid polyurethane foam, which can adapt to temperatures of -185 to 95°C. This kind of insulation material has a soft texture. In order to improve its strength, we need to apply an anti-corrosion coating on the outside of the insulation layer, so we also call this steel pipe an anti-corrosion insulation pipe.

On small and medium-diameter oil pipelines, in order to reduce the heat dissipation from the pipeline to the soil, a composite layer of insulation and anti-corrosion is added to the outside of the pipeline, which will help prevent groundwater from seeping into the insulation layer. Causing unnecessary economic losses.

The anti-corrosion layer of anti-corrosion insulation pipes is generally made of polyethylene material. This anti-corrosion material is odorless, non-toxic, feels like wax, has good low temperature resistance, the lowest operating temperature can reach -70~-100℃, and has good chemical stability , can withstand the erosion of most acids and alkalis, is not soluble in general solvents at room temperature, and has low water absorption. However, because it is a linear molecule, it can be slowly soluble in some organic solvents without swelling, and has excellent electrical insulation properties.
