What gives galvanizing pipelines
All metal structures and pipelines, including, suffer from corrosion and need protection. To cope with this problem helps the use of galvanizing technology. It consists in applying a layer of zinc on the inner and outer surface of the metal, which provides increased resistance to the negative effects of external factors. In addition, such a coating has an inertness to chemical reactions.
Advantages of pipes after galvanizing
Galvanizing of pipelines on EZI allows to apply them on a par with plastic, which almost everywhere displaced metal pipes. Galvanized structures remain in demand as they have a number of advantages:
- the resulting smooth surface does not allow to settle and accumulate on it different impurities;
- galvanized steel construction is easily and quickly assembled;
- have excellent aerodynamic characteristics-allow the air flow to move freely, which provides good traction in the chimneys and the output of combustion products;
- more durable than plastic products;
- do not need additional protection from the negative effects of mechanical and chemical nature.
The pipes after galvanizing improve technical characteristics - their coefficient of thermal expansion is low, the products have increased thermal stability, which allows operation in high temperature conditions. In addition, these pipes are resistant to a fairly high operating pressure and resistant to corrosion. They are the undisputed competitors of plastic.
The process of galvanizing pipelines for water supply is indispensable. After all, zinc is a natural antiseptic that can destroy almost all harmful microorganisms in tap water. This explains the demand for such products in the installation of water systems.
The nuances of installation
Galvanized on the EZI pipe is not recommended to be welded, as the high temperature protective coating can deteriorate and even ignite-zinc just burns out, leaving the place vulnerable to corrosion. A pair of zinc is very harmful to humans - they can cause poisoning. Welding is possible with the use of special electrodes - they produce metal adhesion quickly and galvanized coating does not have time to burn out. You can also use special fluxes that evaporate during the welding process, and the coating remains intact.
But the most reasonable and common is considered a threaded connection.
During installation, it is important to ensure the integrity of these communications. This is achieved by using sealing agents:
- oil paint;
- nitrocellulose enamel;
When installing in the room will need fittings - these reliable galvanized elements allow you to change the course of the pipeline.
