摘要： S P E C I F I C A T I o N TITLE: A lining material for pipe lines A lining material for pipe lines utilizable in a pipelining method wherein a tubular lining material with a binder on the inner surface thereof is inserted into the pipe lines and is allowed to advance within the pipe lines while evaginating the tubular lining material under fluid pressure thereby pressing the tubular lining material against the inner surface of the pipe lines with the binder being interposed between the lining material and the pipe lines, which material comprises a tubular textile jacket, a layer of bulky yarns fastened to one surface of the tubular textile jacket, and an air-impervious layer made of a rubber or a synthetic resin and bonded to the other surface of the tubular textile jacket, characterized in that the bulky yarns are sufficiently thicker than the yarns constituting the tubular textile jacket. This lining material is suitable for reinforcing or repairing various types of pipe lines buried in the ground and possesses earthquake-resistance and shape-maintaining property against external pressure in addition to the characterisitics required for conventional lining materials.

摘要： S P E C I F I C A T I O N TITLE: A METHOD FOR LINING PIPE LINES A method for lining pipe lines used for transporting city water, gas, petroleum or the like fluids. In a conventional evagination-lining method for lining pipe lines which comprises inserting a flexible tubular lining material provided on the inner surface thereof with a binder into a pipe line, with the front end of the lining material being fixed annularly to one end of the pipe line to form a turning point of evagination, and allowing the lining material to advance within the pipe line while moving the turning point of evagination forwards from one end to the other end of the pipe line to turn the tubular lining material inside out under fluid pressure thereby applying the evaginated lining material onto the inner surface of the pipe line over its full length with the binder on the exterior surface of the evaginated tubular lining material being interposed between the pipe line and the lining material, the present invention is characterized in that an unlined portion of the pipe line positioned in front of the forwardly moving turning point of evagination is fully filled with water and that a binder of reaction-curing type capable of reacting with water to initiate curing is used as the binder, whereby the binder on the inner surface of the lining material is continuously brought into contact and react with water as the turning point of evagination moves forwards, and the binder on the outer surface of the evaginated tubular lining material is interposed and cured between the pipe line and the lining material to bond them firmly under the fluid pressure.

摘要： A tubular lining material for reinforcing pipe lines, which has a double-layered structure comprising an air-impervious outer tubular textile jacket provided on the inside thereof with a reinforcing inner tubular textile jacket, characterized in that the reinforcing tubular textile jacket is more coarse in weaving density and larger in diameter than the air-impervious tubular textile jacket and that the product of the length of the diameter and the elongation ratio in the direction of the diameter on fracture, of the air-impervious tubular textile jacket is approximately equal to the product of the length of the diameter and the elongation ratio in the direction of the diameter on fracture of the reinforcing tubular textile jacket. The tubular lining material is excellent in both pressure-resistance and earthquake-resistance so that even if the pipe lines are cracked or broken off by strong external force caused, for example, by earthquake, the tubular lining material is merely detached from the damaged pipe lines, without being destroyed, to maintain its function of providing a passageway for a fluid transported under high pressure.

摘要： A tubular lining material for city water pipe lines, which comprises a tubular textile jacket made of warps and a weft woven in a tubular form overlaid with a fluid-impervious coat of a flexible synthetic resin, at least one of the warps and the weft being comprised of threads manufactured by intertwisting filament yarns with spun yarns and/or spun-like textured yarns of synthetic fibers, and the flexible synthetic resin comprising a blend of 60-40% by weight of a polyethylene resin and 40-60% by weight of a styrene-ethylene-butylene-styrene resin, having a stress-crack resisting property of at least 1000 hours which penetrates the interstices of the fabric structure of the tubular textile jacket. The tubular lining material is remarkably improved in flexibility, heat-resistance, abrasion-resistance, stress-crack resistance and other mechanical strength properties and is harmless to drinking water.

摘要： A tubular lining material for pipe lines having bends or curved portions, which comprises a tubular textile jacket made of warps and wefts woven in a tubular form overlaid with a coating of a flexible synthetic resin and is applicable onto the inner surface of a pipe line having bends or curved portions in such manner that the tubular lining material with a binder onto the inner surface thereto is inserted into the pipe line and allowed to advance within the pipe line with or without the aid of a leading rope-like elongated element while turning the tubular lining material inside out under fluid pressure thereby applying the tubular lining material onto the inner surface of the pipe line with the binder being interposed between the pipe line and the tubular lining material, characterized in that a part or all of the warps are comprised of an elastic yarn around which, over the full length thereof, a synthetic fiber yarn or yarns have been left-and/or right-handedly coiled. This tubular lining material is particularly suitable for use in a lining method taking advantage of evagination as disclosed in U.S. Pat. No. 4,334,943 for lining a pipe line having an inner diameter of 25-200 mm and a plurality of bends, such as service pipe lines or house pipe lines of gas without occurrence of wrinkles in the lining material in a bend.

摘要： METHOD AND APPARATUS FOR PROVIDING THE INNER SURFACE OF A PIPE WITH A FLEXIBLE TUBULAR LINING MATERIAL A method and an apparatus for providing the inner surface of a pipe with a flexible tubular lining material by means of liquid resin under pressure comprises fixing one end of such material so that it is turned inside out at the fixed end. Fluid pressure is then applied from the rear of the assembly to push the lining material forward within the pipe while effecting evagination of the lining material to attach the inner surface of the lining material exposed by evagination under pressure tightly to the inner surface of the pipe. The invention is characterized by previously forming a reservoir of the liquid resin enclosed in the interior of the unevaginated portion of the lining material positioned in the rear of the fixed portion. The lining material is passed through the reservoir to apply the resin to its inner surface. The lining material is squeezed externally to adjust the quantity of the resin applied to this inner surface. The liquid resin-applied inner surface of the lining material is then applied to the inner surface of the pipe under pressure to form a flexible tight lining. This method is advantageously utilized for preventing leakage of various kinds of gas and liquid from pipes.
