  • Lining material for pipelines
    Patent number: 5164237
    Abstract: A lining material adapted for lining the inner surface of pipelines for transferring various kinds of fluids such as city water, sewage, city gases and petroleum, etc., characterized in that low elongation high tensile strength filament yarns are used as wefts (5), (16) forming tubular textile jackets (2), (6) laid in the lining material or as the yarns (12) forming a tubular fibrous member (13) together with a tubular textile jacket (2'). This characteristic feature provides excellent performance required for lining materials for pipelines such as enhanced earthquake resistance and shape retaining property against external pressures and limited expansion in diameter.
