Galvanizing of pipes in Chelyabinsk
Today, pipes are used in many areas. With their help, spend sewer system, heating, water supply. Often pipes are used in urban construction. Steel structures are involved in the construction of the infrastructure of the city – the construction of playgrounds, public transport stops, billboards. Galvanized pipes are purchased for plumbing purposes or road construction.
In any field of application, steel will have high performance and attractive appearance. The only significant drawback of the metal-high susceptibility to corrosion. There are several ways to protect the pipe-the most popular is galvanizing.
Galvanizing of pipes in Chelyabinsk is carried out in accordance with all the requirements of GOST. The resulting products have advantages in comparison to other black metal:
- high performance properties;
- the strength of the material, the ability to recover from minor damage;
- resistance to the development of pathogenic bacteria on the surface;
- treated pipes are not exposed to high temperatures and corrosion;
- the parts can withstand high pressure from the inside.
To obtain a quality result, hot-dip galvanizing or diffuse treatment is most often used.
When hot-dip galvanized pipe is first thoroughly cleaned. With the help of several types of acids and alkalis, oils, synthetic compounds, rust are removed. Several times washed. After all manipulations immersed in a ceramic vessel filled with zinc heated to 450 degrees. Withstand 3-10 minutes, lift and remove the formed slags. Hot dip galvanizing is considered to be the most cost-effective way to protect the metal from corrosion. After such treatment, the pipe significantly increases its service life, up to 50 years. The zinc melt penetrates deeper into the metal structure every year (2 mm per year).
Diffuse treatment is somewhat different. The pipe is placed inside a closed container and processed with hot zinc vapor. Thermal diffusion is carried out at a temperature of 290-450 degrees. Zinc penetrates into the intergranular lattice of iron. This method is more expensive in comparison with galvanizing, but the surface of the metal is covered with a protective layer more evenly and evenly. Additionally, in addition to the anti-corrosion properties of electrochemical protection. Black metal is converted to cathode.
Galvanizing pipes in Chelyabinsk opens up new opportunities for the use of steel products. Details can be used even in the construction of structures in the open air, where the pipe will be regularly exposed to water and temperature changes.
