Protection of pipelines against corrosion of metal plumbing

Protection of pipelines against corrosion of metal plumbing is one of the major problems in the operation of water supply systems, created with metal pipes. Metal pipes require protection of pipelines that pesky chemical reaction as corrosion. Under the influence of atmospheric moisture and the formation of various chemical precipitation of metal compounds such as oxides. Among these compounds, requiring protection of pipelines running water include:

rust steel
green patina on copper, etc. unpleasant and destructive phenomenon for metal

When laying new pipelines to supply hot and cold water pipes better use of synthetic materials are not afraid of corrosion.

Consider the types of corrosion that force us to implement effective protection of pipelines running water.

External corrosion that requires protection of pipelines, mainly occurs due to the fault of high humidity and precipitation of condensate on the walls of an iron or steel pipe. At a high level of air humidity occurs such an unpleasant phenomenon as deposition of condensation on the cold metallic surface of the tubes. That is why it is necessary to protect the pipeline put cold water pipe in a vapor heat-insulating fiber sleeve, designed for exactly this purpose.

Protection of pipes with copper pipes protect against corrosion processes using the shell of a fibrous material coated with a specialized plastic film. Brazed joints in copper tubing require special attention: you come to the aid of an additional band of fibrous materials and plastic film.

Protection of piping hot water is pre-emotive use of synthetic or composite materials to form protective shells.

It is important to keep firmly in mind when installing plumbing pipes that the reliable protection of pipelines is vital to avoid contact with metal pipes salt solutions, as chemically aggressive environment is well-known catalyst for corrosion processes. Provide good protection sleeve or ribbon of laminated composite materials.

If you want to pipe embedment, the la protection apply only solution of high-early strength cement. Plaster solutions should not be used for these purposes.

In addition to the external metal pipes as well and are subject to internal corrosion. It depends in most cases on the chemical composition of the water in your area. Just on the flow rate of corrosion processes and renders the liquid temperature inside the metal pipe. The relationship between the composition and temperature of the water is very complex, and can not always be provided for the emergence, for different materials require different conditions. For example, to protect pipelines from copper need maximum heating water supplied. In a steel to protect the water pipes must be heated to a temperature range of 50 to 60 degrees Celsius.

Protect pipelines and other necessary negative phenomena such kA, for example, ingestion of foreign bodies of metal pipes:
rust
sands
particles of clay
Synthetic small elements, etc.
It is not difficult to do using special filters. When installing pipes pipeline protection is to avoid getting metal shavings or soldering residues inside the tubes.

To improve reliability, protection of pipelines corrosion processes must clearly know and always abide by simple rules: copper pipes downstream of the water is always laid only after steel.
