Method of manufacturing a syntactic sleeve for insulating a pipeline |
摘要 |
A spincasting technique for forming a syntactic insulation layer around a pipeline includes rotating a drum while or after injecting components for forming syntactic insulation material into said drum. In this manner a syntactic material is formed in which larger, low density, microspheres are biased towards the inner surface of the insulation layer.
