Floatable double skin hose - has plastics coated outer layer and intermediate space filled with thermal insulating material

摘要

The floatable, double-walled flexible hose has an intermediary space between its two layers. The layers are composed of metallic coils (1, 12), and there are radial distance pieces (16, 17) between them. The inner metal hose is pref. of the ring-wave type (1), and carries the stranding (2), whilst the outer hose is of the coil type (12). The outer hose has a plastics outer cover (13), and at least one of the two hoses has a thermic insulation layer. This layer (16, 17) fills the intermediary space between the two hoses.
