Galvanizing of pipes in Yekaterinburg
Pipes are used for laying water supply, communications, Central heating systems for several hundred years. All this time the person seeks to find a way of strengthening of pipes, to increase their wear resistance.
The most common material for the production of pipes – steel. The cost of metal is relatively low, and the performance characteristics are of decent quality. Steel perfectly transfers heat, withstands high temperatures, while being durable and reliable. The only drawback of the material – the susceptibility to corrosion. The most popular method of corrosion protection in Yekaterinburg – galvanizing pipes, coating the metal surface with zinc melt.
The advantages of galvanizing are obvious:
- maintaining high heat, energoproject;
- increased service life by 30 years;
- self-healing in case of mechanical damage to the surface;
- resistance to the development of pathogenic bacteria.
Processes of galvanized pipes in Ekaterinburg a few. The first option is to thoroughly clean the metal surfaces from oil, synthetic compounds, rust, scale. Rinse and dry the product. After preparation, the pipe is lowered into zinc, heated to 450 degrees for 3-8 minutes. The method is called hot-dip galvanizing.
The second method – electroplating. If necessary, galvanizing steel will be the most expensive method, but providing an attractive even coating. In addition, there are some disadvantages of the method:
- high costs with low productivity;
- strict requirements to surface structure;
- only small - sized products are suitable for processing.
The last method is thermal diffusion. The steel pipe is placed in a closed container for processing with hot zinc vapor. It is considered the most reliable way – zinc particles faster and better grasp each other.
The advantage of thermal diffusion is:
- possibility to cover even hard-to-reach pipe parts;
- resistance of the coating - zinc does not peel off during the operation of the product.
Thermal diffusion has its drawbacks-a fairly high cost and the inability to cover long productsя.
Galvanized pipes are used for water supply, heating, sewage systems. Often pipes are used in urban construction – in the construction of billboards, playgrounds, public transport stops. Technological literacy it is important to carry out processing of the metal. Then properly conducted galvanizing pipes will be absolutely safe for humans-during the application of zinc and during operation.
