What anti-corrosion material is suitable for the external anti-corrosion protection of low-temperature buried pipelines?
Thread Content
Low-temperature liquid carbon dioxide pipeline: medium temperature of -25 degrees Celsius; pipe material with a pressure rating of 16 MPa; buried in the ground; low temperature around -20 degrees Celsius. The project is located in Inner Mongolia, where the lowest local ambient temperature can drop below -40 degrees Celsius. What is a suitable method for external anti-corrosion in such environmental conditions?
Many types of techniques will work; it is recommended to use an inner epoxy layer, glass wool for the insulation layer, and polyurethane or polyurea for the outer layer
3PE is also okay. But be sure to choose a good manufacturer.
Can 3PE be applied in conditions where the medium temperature is below -20 degrees and the ambient temperature is below -40 degrees? Of course, the low temperatures encountered when pipelines are buried are not that low; the lowest temperature is likely around -18 degrees
