    • 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.
    • 纺织管包括内涂层和外涂层,以及由设置在涂层之间的高拉伸强度和高模量强度的纤维(高性能纤维)制成的由经线和纬纱制成的材料。 经线沿管的纵向布置,纬纱沿管的圆周方向排列。 内外涂层由热塑性合成材料制成。 纬纱宽度为至少8,000分特(dtex),优选为10,000dtex以上。 经线宽度为2000dtex以上,优选为3000dtex以上。 纬纱密度至少为40,优选为50以上。纺织管特别适用于清洗高压液体管线。 由于其超过90巴的高爆破压力,纺织管​​不必粘在管道内壁的大表面区域。 旧管道的公称压力可以通过清洁程序大大增加。
