Sewer pipes for outdoor sewerage

Main requests to overflow pipes

When there are construction works on all communication networks, in use, always include laying pipes for both external and internal networks to divert runoff.Specific requirements for such systems can be specified in the regulations, as well as the estimated discharge of effluent.Pipelines that are on the outside, must meet these requirements:

• Have good resistance to dynamic and static response.
• After backfill soil, not deformed.
• be resistant to different types of loads (vehicles, people).
• If surface water change, such pipes should not be exposed to shifts in the butt nodes.

During the construction of residential buildings, industrial facilities, the pipeline has to be laid in the trench, and to be excavated below the marks of soil freezing.Such rules are spelled out in the special guests that are available today.

All values ​​can be found in certain metrological services, they have all the data on construction works on certain sites.If the processes of laying pipelines originate outside the city, then the installation depth is 0.5 - 2 meters.Also, it depends on the terrain and location of the house.

Sewer pipes for outdoor sewerage crossing the most important system of roads, should have a high degree of outer load.To do this, you must use a very strong pipe.Apply drainage system, wrapped in corrugated materials.Such metal-plastic pipes have high flexibility.

External piping systems and material manufacturing

For good quality and devices external drainage systems, it is necessary to pay attention to their frost resistance, corrosion resistance, as well as the strength of the exploited material, since it affects the durability of the device.

Very often used steel pipes for outdoor sewerage, but they have a number of negative characteristics:

1. They are very susceptible to corrosion and at least work well for several years.
2. bandwidth is not high.Deposits occur in the walls, which reduce the flow passage through the system.

also used plastic pipes, they are much better than steel and steel perfect replacement for them.They have a great range of positive characteristics, such as:

1. have good strength.
2. durability of more than 2-3 years.
3. Light in transit.
4. Installation work is very easy and not time consuming.
5. for unstable systems, as well as for the mobile soil they are flexible.
6. also have good resistance to frost and can be installed in the cold season.

However, such systems have a number of negative qualities, for example - is the low strength of laying them under a certain bias.To resolve this problem, recommend the use of double-walled pipes or corrugated.

Installation works Installation works

for external drainage systems have such properties:

1. almost always used in country houses pipes with a diameter of 100mm.
2. to use polyethylene union, you must operate fairly expensive equipment.Most often it is used for welding.
3. Polyvinyl chloride pipes more advantageous for the device, as well as less expensive when choosing equipment.
4. It may be that the sewers are laid, not too deeply, for this they need to, to warm, to avoid gaps.If such a system is laid below, while insulation processes are not required.

External plumbing system to drain runoff must be warm, so as not to have any problems, such as an accident, as well as the pipelines do not be frozen, and everything will work as well.This factor is very important and should not forget it.
