Definitions
- the invention relates to a method for cleaning and coating pipelines intended for water guidance.
- the chemical composition of the drinking water flowing in metallic pipes and devices has an influence on the corrosion and / or the formation of stones on the pipe walls.
- Very soft to soft water attacks metallic 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 a method for cleaning and coating pipelines intended for water management, with which it is possible to renovate existing pipelines, in particular smaller dimensions, so that these pipelines can then continue to be used.
- the pipelines are closed at individual points with ventilation plugs before coating the pipelines in accordance with method step d) and, after filling, vented at these points by means of the liquid plastic.
- the liquid plastic filled in according to method step d) remains in the line under about 6 atm pressure for about an hour.
- the excess plastic material which does not adhere to the walls of the pipelines is blown out from all high points by means of compressed air.
- the existing 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 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.
- a rough cleaning using water and compressed air takes place first in accordance with method step a).
- a compressed air / water mixture is pressed into the pipes.
- 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. flow away.
- an acid corresponding to the pipe material, for example hydrochloric acid
- an 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 pipe network for a correspondingly long time depending on the degree of contamination.
- Lime and rust must also be dissolved here (procedural document b).
- 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 drained off.
- the pipe is coated with plastic.
- 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.
