  • Patent number: 4526208
    Abstract: A tile-lined pipe and its method of manufacture comprising a tubular pipe member having a layer of tile elements on the inner surface to form a lining therefor. The tile elements extend one after another along helical lines and are formed by subdividing larger tiles transversely along score lines so that the adjoining faces of the subdivided tiles will be in closely conforming adjoining relation. Within the tile elements is an erodible layer. The structure is encompassed by resin saturated fiberglass. The resin serves to absorb energy from impacting particles.
