superposed turbines for ultra-deep waters.

摘要

Sandwich Pipeline for Ultra-Deep Waters comprised of a composite system with three or more superposed layers, characterized by an inner layer and an outer layer made of metal such as carbon steel, stainless steel, aluminum, titanium, alloys etc., and an intermediate layer made of cement, polypropylene, ceramic materials, polymers or composite materials with low thermal conductivity, high mechanical strength and good adherence with the internal and external pipes.
