Abstract
A composite stripwindable to form a helical pipe is disclosed. The composite stripcomprises: an elongate plastic striphaving a base portionand at least one lengthwise extending rib portionupstanding from the base portion; and an elongate reinforcing stripextending lengthwise and supported laterally by the rib portion, the reinforcing striphaving a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion. When wound into a helical pipe, the reinforcing stripreinforces the pipe against radial crushing loads. A beadseals the reinforcing stripfrom the environment. Desirably the composite stripfurther comprises: a planar laminaextending lengthwise and bonded to the base portion, the laminahaving a higher Young's modulus and strength than those of the plastic strip. The laminagreatly improves the pressure rating of a pipe wound from the strip
