Possible materials for the manufacture of sewer pipes
The concept of "sewer pipe" has a number of specific features that must be taken into account when installing sewerage lines. These features are formed based on the conditions in which the drainage is installed, the technical characteristics of the building, as well as the material capabilities of its owner. All these aspects directly affect the choice of the type of pipe fittings for sewerage.
This type of material for the installation of drainage systems can be made of different materials. These materials can be:
- Metal.
- Ceramics.
- Reinforced concrete.
- Polymers.
Each of the above materials has its own specific performance characteristics, as well as installation features. Later in the article, each type of pipe for installation of sewage systems will be described and described.
Pipe fittings for drainage from metal
Pipes for sewage of this type are the most common for the use of large-scale drainage systems. Such pipe fittings can be of two types: steel and cast iron.
Metal sewer pipes made of steel have the following characteristics:
- Relatively low cost of products.
- High strength.
- Resistance to mechanical influences.
- Ability to withstand high loads.
- High coefficient of heat resistance.
Disadvantages of using steel pipe products for sewerage:
- High specific gravity of the product, which greatly complicates transportation and installation.
- Low resistance to corrosive processes. This significantly reduces the service life and increases the risk of damage to the sewer pipe.
Sewer pipe made of cast iron has the following technical characteristics in comparison with steel pipe products:
- Greater strength.
- Greater resistance to mechanical stress.
- Longer service life.
The drawbacks of using this type of pipeline materials are:
- Greater than for steel pipes, the bulkiness and specific weight, which greatly complicates the process of transportation and installation.
- Significant roughness of the surface, which contributes to the occurrence of various kinds of blockages.
- High complexity of joining separate parts of pipe fittings with each other during the installation process.
Thus, pipes for sewage from metal have a large number of distinctive features. The main advantage of this type of pipe products is a high coefficient of strength, as well as a long service life.
Ceramic fittings Ceramic
This type of water pipe is used in outdoor sewerage systems, the passing fluids of which do not have pressure and move within the communications by gravity.
Pipes of this type are household, rain and industrial. The main advantage of this type of pipe fittings is their cheapness. But at a low price, such a figure is hidden as low strength, so this type of pipe can not be used in drainage systems with high intensity of drainage substances.
This type of tubular products must have a certain number of specific properties:
- There must be several grooves on the products: at the end of the pipe from the outside, and inside - on the socket.
- The ceramic pipe fittings must withstand a pressure of 0.2 MPa.
- Inside and outside the pipe must have a layer of ceramic glaze that resists the effects of chemical elements.
- In the production of this type of pipe products, they must be fired at a temperature of not less than 1300 degrees inside and outside.
The big advantage of pipeline products from ceramics is the fact that after their damage or disabling it is possible to use parts of the product on the farm. So the shredded material is suitable as a tamping layer for the foundation, from the parts of the ceramics can be mounted all kinds of ebb for various buildings.
Piping products for canalization from reinforced concrete
This kind of drainage fittings is used in various types of construction as part of non-pressure sewage systems. The material from which the ferroconcrete sewage pipe is made must be marked with water permeability. The markings can be: M350, F200, W6, B25.
The main characteristics that distinguish the pipes from reinforced concrete are:
- Compressive strength.
- Stretching strength.
- Coefficient of resistance to low temperatures.
- Water resistance level.
In terms of technical characteristics, this type of pipe is divided into several types, which depend on the possible depth of the drainage system:
- At 2 meters.
- At 4 meters.
- At 6 meters.
The main distinguishing features of this type of sewerage fittings are their low price and resistance to chemical influences.
Pipes for sewerage from polymers
At this stage of development of building technologies, this type of drainage fittings is the most common due to the large number of characteristics that a sewer pipe from various plastics possesses. Among this type of pipe products, it is possible to distinguish pipeline fittings made of polyvinyl chloride and polypropylene. This type of pipe fittings is easy to install and transport. Most suitable for domestic sewage. Minuses are low resistance to too low and too high temperatures.
Thus, the article described and described all types of drainage fittings that can be used in the installation of modern sewer systems.
