ABSTRACT:
A flexible composite pipe capable of being wound on a reel and quickly deployed at low cost while floating empty and carrying water from one location to another and being rewound after use, the pipe having a minimum burst strength of about 3,000 psi, a minimum tensile strength of about 130,000 lbs. of tension, a specific gravity less than that of water when full of air and a specific gravity greater than one full of liquid, the pipe including a flexible core tube of thermoplastic material having a compressive strength of less than about 4,000 psi, an inner aramid fiber layer radially disposed about the core tube providing radial strength to the pipe, an inner tape layer radially disposed about the inner aramid fiber layer, an outer aramid fiber layer radially disposed about the inner tape layer to provide further radial strength to the pipe, an outer tape layer radially disposed about the aramid fiber layer, an inner steel armor wire layer helically wound about the outer tape layer providing radial strength, longitudinal strength, cut resistance and twist resistance, an outer steel armor wire layer oppositely and helically wound about the inner steel wire layer and a flexible pipe jacket of scuff resistance plastic polymer material.
