Asbestos-cement (asbestos cement) pipes are a building material made of asbestos fiber and Portland cement.
Asbestos and cement for the manufacture of pipes are taken in the proportion of 15:85.
Types and applications of asbestos-cement pipes
There are two types of asbestos-cement pipes - pressure and non-pressure pipes.
Pressure pipes have an internal diameter of 50 to 600 millimeters. Their length is 5 meters. Such pipes are designed for high pressure - 6 or 9 atm.
Typical for asbestos-cement pressure pipes is durability and low hydraulic resistance. So they have found wide application in construction.
Pressure pipes are used when installing pressure water pipes, laying a gas pipeline, pressure irrigation and melioration systems.
Asbestos cement pressure pipes are used in the arrangement of wells, wells. They are also used to shut down farm buildings, under animal feeders.
The disadvantage of asbestos-cement pipes is their increased brittleness, which causes inconvenience in the process of installation.
Apply pressure pipes for the construction of pressure sewers, dykes and iloprovodov.
Non-pressure asbestos-cement pipes in length can be from 2, 95 to 5 meters. The internal diameter can vary from 50 to 500 millimeters.
Such pipes are used for installation of external pipelines of non-pressure engineering networks - sewerage, chimney, garbage chute, air vent.
Non-pressure pipes are also used asMine or a box at a lining of telephone and electric cables. Since this type of asbestos-cement pipes has a high electrical resistance and is not afraid of electrochemical corrosion.
Use non-pressure pipes as supports, posts and piles when installing fences and other fences.
Advantages of asbestos cement pipes
One of the most important advantages of asbestos-cement pipes is their durability. They can serve 30-40 years.
Such pipes are resistant to corrosion and aggressiveEnvironment, they are easy to install and process. Asbestos-cement pipes have low cost and low weight. Listing the advantages of these pipes, we can not fail to mention the absence of the need to protect them from stray currents and groundwater.
The garbage disposal and sewage system from this type of pipe does not adversely affect the condition of the soil and the environment.
Since the asbestos-cement pipes have goodHeat protection characteristics, when constructing a water pipe, they can be laid to a shallower depth than cast iron or metal. The water in such pipes will not freeze when the temperature decreases.
