ABSTRACT:
A flexible, fiber reinforced pipe has been invented for conveying fluids. The pipe is flexible enough to be spoolable, even under winter temperature conditions. The pipe can contain pressure, when buried, unrestrained and bent. The pipe exhibits impact resistance under normal handling and can be formed using a continuous process, such that it can be manufactured as it is being laid. A flexible, fiber reinforced pipe includes an inner tubular liner having an inner surface and an outer surface; a first layer of reinforcing fibers helically wrapped about the inner liner and in direct contact therewith; an outer layer of reinforcing fibers helically wrapped about an underlying layer of reinforcing fibers and in direct contact therewith; and an outer tubular sheath applied over the outer layer in direct contact therewith.
