A textile tubing comprises inner and outer coatings, and a material made of warp and weft threads manufactured from high tensile strength and high modular strength fibers (high performance fibers) disposed between the coatings. The warp threads are arranged in the longitudinal direction of the tubing and the weft threads are arranged in the circumferential direction of the tubing. The inner and outer coatings are made of a thermolastic synthetic material. The weft thread width is at least 8,000 decitex (dtex) and, preferably, more than 10,000 dtex. The warp thread width is at least 2,000 dtex and, preferably, more than 3,000 dtex. The weft density is at least 40 and preferably more than 50. The textile tubing is especially suitable for cleaning high pressure liquid lines. The textile tubing does not have to be stuck to large surface areas of the inner wall of a pipe due to its high burst pressure of more than 90 bar. The nominal pressure of the old pipes can be substantially increased by the cleaning procedure.
