ABSTRACT:
A portable, modular and easily applied protective pipeline covering which resists impact, penetration and tearing while providing an appearance which enhances visibility. In certain embodiments, a plurality of layers encodes information on the substance carried by the pipeline and the depth of penetration of any tear or abrasion. The covering comprises a resilient wall matrix and may include an outer layer which is relatively penetration-resistant. Modular covers may be flexible, semi-rigid or rigid. They are applied in modules which each comprise one or more pieces which substantially conform to the pipeline surface, being held in place by circumferential tension elements or, in the case of flexible covers which are wrapped or wound on a pipeline, may be inhibited from unwinding by circumferential tension elements or adhesion means coupled to the cover material. Each cover module has attachment means on each end to allow linking of cover modules after placement on the pipeline. In certain embodiments, fiber reinforcement is embedded in the resilient wall matrix, an outer layer (if present), or both, to better resist penetration and tearing of the cover.
