EXTRUDED ENCAPSULATED FILLERS TO PROVIDE CRUSH PROTECTION |
摘要 |
In various embodiments, a tubular comprises a tubular outer sheath defining an inner void; one or more core elements or assemblies disposed within the inner void; and a substantially solid filler in various embodiments disposed within and substantially filling the inner void, where the filler is adapted to give the tubular hoop strength in a crush situation and comprises a polymer with a density of at least 1.0. In some embodiments, these core assemblies comprise an extruded polymer layer typically extruded about core elements in a single pass, fitting about them without a sharp edge and defining an outer shape. The resulting tubular can comprise multiple regions which, though substantially filled, are filled with differing fillers densities. |
