Definitions

  • the invention relates to a method for renovation by means of cleaning and coating of pipelines intended for water management.
  • the chemical composition of the drinking water flowing in metallic pipes and equipment has an influence on the corrosion and / or the formation of stones on the pipe walls.
  • Very soft to soft water attacks metal materials almost unhindered without any noticeable formation of protective or cover layers.
  • the metal dissolution usually takes place over the entire water-wetted surface, with corrosion products being carried along by the water.
  • the object on which the present invention is based is to propose an advertising-improved method for renovation by means of cleaning and coating of pipelines intended for water guidance, with which it is possible to renovate existing pipelines, in particular smaller dimensions that these pipes can continue to be used afterwards.
  • the pipes are closed at individual points with ventilation plugs before the pipes are coated and, after filling, vented at these points by means of the liquid plastic.
  • the filled-in liquid plastic advantageously remains in the pipeline for about an hour at about 6 atm pressure.
  • the excess plastic material not adhering to the walls of the pipelines is then blown out from all high points by means of compressed air.
  • an existing pipe a water pipe is installed in the wall. It consists of various materials, in particular galvanized threaded pipe according to DIN.
  • the cause or reason for the renovation is usually the constant pitting and rust in the water described above.
  • the water is turned off and the pipes to be renovated are emptied.
  • the existing sanitary fittings and devices are dismantled and the openings created are bridged.
  • the method according to the invention is for cold water pipes, hot water pipes and heating lines are provided. It is possible to renovate both copper piping and galvanized steel piping. Dismantling and relocating the pipelines in apartment blocks would be very expensive and costly. In addition, various handicrafts (tilers, painters, bricklayers, decorators) would still have to be carried out.
  • the various cleaning steps serve to achieve a surface that is as bright as possible metallic, d. H. to remove all incrustations, rust spots, lime residues.
  • rough cleaning is first carried out using water and compressed air. At one connection, a compressed air / water mixture is pressed into the pipes. At other points, flexible drain hoses are attached that lead into a collecting container. This process is carried out until the first coarse dirt, impurities, rust particles, etc. drain off.
  • an acid corresponding to the pipeline material, for example hydrochloric acid
  • hydrochloric acid is now preferably filled in under pressure at the same point at which the compressed air / water mixture was previously supplied and remains in the pipeline network for a correspondingly long time depending on the degree of contamination.
  • lime and rust must also be dissolved.
  • This acid can also be filled in hot, for example. It has also proven to be advantageous to use an inhibitor in this acid which is intended to prevent the pipes from rusting immediately after the acid has been discharged.
  • the excess plastic material not adhering to the walls of the pipelines is then blown out from all high points by means of compressed air.
