Lining material for pipelines

Abstract From the Canadian patent

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, forming tubular textile jackets laid in the lining material or as the yarns forming a tubular fibrous member together with a tubular textile jacket. This characteristic feature provides excellent performances required for lining materials for pipelines such as enhanced earthquake resistance and shape retaining property against external pressures and limited expansion in diameter.
