ABSTRACT:
A tubular structure, such as a pipe or pressure vessel, is provided with a wall formed from plastic, composites and elastomeric materials. The composite materials are spirally wound and are separated by elastomeric strips. The wall has an inner wall element formed by a continuous flexible plastic cylinder with a spiral projection on its outer surface. An outer layer is formed from alternating spirally wound strips of composite and elastomer. The composite strip has a radially inward projection axially spaced from the projection on the plastic cylinder but overlapping in the radial direction. The cylinder and layer are separated by an intermediate layer formed from composites and elastomeric strips. A composite strip is located between each pair of adjacent projections and separated from the projections by an elastomeric strip. An outer wall element is formed from alternating spirally wound composite and elastomeric strips having pitch greater than the inner wall element.
