BUOYANT HOSE AND METHOD FOR MAKING SAME |
摘要 |
The invention relates to a buoyant flexible hose and method for making same wherein buoyancy is imparted to the hose by an annular sleeve which surrounds said hose and is constituted by an inner layer consisting of a series of axially successive preformed annular bodies of cellular high polymer which are surrounded by an outer layer of a wear resistant polymeric material with the interposition of an intermediate layer of a reinforcing fabric between said inner and outer layers. The outer layer is formed in situ and together with the intermediate layer constitutes a unitary body structure, which is continuous and uninterrupted in the entire extent along said axially successive annular bodies.
