  • Lining hose are introduced into the pipe system to be rehabilitated in the hose, which brings a number of problems.
  • the uniform impregnation of the inner layers of such a lining tube is difficult to achieve, which adversely affects the product quality of the installed hardened tube.

  • Mirror lugs is usually a pipe, or a portion of such, referred to, in the water or a fluid medium according to the law of gravity passes from a higher starting point to a lower end point, wherein the cross section of the line or the line section is usually not fully flowed through, so that in contrast to a pressure pipe usually a free liquid surface remains.
  • the line is thus not completely filled by the liquid, but it remains an air volume which begins at the upper end of the free-flow line and, depending on pressure and gas solubility, extends more or less far down. Since the fluid medium is conveyed in a gravity pipe only by gravity, free-flowing pipes are sometimes called

  • Resin-impregnated fiber hose based on a composite of (c1) industrially produced inorganic fibers, natural fibers or mineral fibers and (c2) chemical fibers.
  • a composite or composite material within the meaning of the present invention is generally a material of two or more interconnected materials having different material properties than its individual components. Material properties and geometry of the components are important for the properties of the composites. In particular, size effects often play a role.
  • the connection is made by fabric or form-fitting or a combination of both.
  • Composite materials are mixtures of unmixed raw materials. A solution of the individual basic materials with each other does not take place or only superficially. By compounding thus at least two substances are interconnected. The aim is to ensure an intimate connection of the phases over the long term and under load.

  • Fiber scrims are a processing variant of fibers in which the fibers are not interwoven, but are aligned parallel or at an angle to each other and optionally fixed by means of a step path or an adhesive. Fiber scrims, especially fiber scrims with parallel fiber orientation, may have a pronounced anisotropy of the orientational orientations and perpendicular thereto due to the orientation of the fibers, which may be of interest for some applications.
  • a nonwoven consists of loosely connected fibers, which are not yet connected to each other. The strength of a fleece is based only on the fiber's own liability, but can be influenced by work-up. In order to be able to process and use the fleece, it is usually solidified, for which various methods can be used.
  • Nonwovens are different from fabrics, or knitted fabrics, which are characterized by a certain production of the laying of individual fibers or threads.
  • Nonwovens consist of fibers whose position can only be described by the methods of statistics. The fibers are confused with each other in the nonwoven fabric. Accordingly, the English term nonwoven (non-woven) clearly distinguishes it from woven fabric.
