pipes for sewerage - product without which today we can not imagine any one comfortable accommodations.What is the importance of sanitation and its full functionality, known and understood by everyone.But still the question remains, what is better for sewage pipes, because their range is wide, and the sewerage system should serve as a reliable and high quality.


modern alternative to outdated pipe rolling ↑

waste and dirty water discharged by the sewer system, which in turn is divided into external and internal.The system of domestic sewage is one of the most necessary modern utilities.In 60-70 years, the traditional sewage system was constructed mainly of ceramic or concrete pipes.But progress does not stop, there are alternative materials, so the replacement of sewer pipes are highly relevant today, and i

t is not surprising, modern lines have indisputable advantages:

- the absence of electromechanical corrosion;

- smooth inner surface of the pipe - flow losses are reduced friction;

- labor saving (2-3 times)

And plus to all, the cost of plastic pipes by 30-50% cheaper than metal.

Types of sewer pipes ↑

First of all sewer pipes are divided into two main types: plastic and iron, that is, depending on the material.

iron - a traditional solution ↑

Cast iron pipes for sewage systems have been used for a long time and are widely used for this purpose.This is a classic genre, and the cast iron is characterized by many positive qualities.

These pipes are durable, strong, sewage pipes of iron operated for many years.But despite the benefits, there are also some disadvantages, for example, imposing the costs of metal and, as a result, a great weight of finished pipes.

Moreover, the inner surface is characterized by roughness and therefore creates a resistance to the flow of water, for this reason, inside the iron pipe incrustation.Installation because of the large weight of the pipe is complicated and time consuming.Well, the most significant disadvantage of cast iron pipes are expensive, because the production of this metal is not cheap.

Plastic pipes, priorities ↑

Plastic pipes for sewage systems provide the functionality of the quality of communication.These pipes are used for indoor and outdoor sewage.

They have a number of advantages:

  • smooth surface creates favorable conditions for the tubes do not form blockages;
  • light weight - a great indicator for the transportation and installation.When installing special equipment is not used, sealing solution - plastic pipe is simply inserted into the socket of another pipe, with seal of quality rubber, which provides a seal for many years.Alternatively installation is carried out with the help of fittings;
  • low cost compared to steel and cast iron;
  • durability.

important: the correct installation, taking into account all the requirements and standards, provides an excellent opportunity to the device space with a neat appearance.That is, the pipes can be hidden in walls and floors, without worrying about their integrity.

Plastic pipes for outdoor sewerage and internal inter alia, made of three types of plastic: high-density polyethylene, a brief PVP, polyvinyl chloride - PVC and polypropylene - PP.

PVC pipes

PVC sewer pipes are used mostly for sewer gravity type.They are resistant to ultraviolet radiation, and low linear expansion coefficient is suitable for sewage purposes.PVC pipes are characterized by high strength and good resistance to mechanical damage and drains kept the 70-degree temperature.But the fact of exposure to chemicals, corrosive liquid detergents and high temperatures adversely affect the condition of the pipes, damaged the walls and there is a plaque, which eventually turns into a blockage.


Polyethylene pipes for sewerage are designed for internal and external pressure pipelines.They are the most heat sensitive and are subject to expansion at high temperatures.- 40 ° C to + 40 ° C - Low operating temperature range of polyethylene pipes, so sewer drain with hot water can not be predicted.

polypropylene pipes for sewerage

pipes for external and internal sewage systems may be polypropylene.This excellent pipe, commonly used for the device drains from the dishwasher and washing machine, as they have resistance to the ravages of alkalis and acids.And they are resistant to mechanical damage and can withstand temperatures up to 100 degrees, and it is very good quality.

Flexible corrugated pipe

Pipes for drainage, especially applied to suburban areas - Corrugated double layer.Corrugated pipe for sewer has ring stiffness and high strength, so it can be used in places of strong load.And performance of flexibility significantly reduce the number of fittings and substantial cost savings.

Sewerage pipes are painted in orange or brick-red color.At the same time, domestic sewage pipes are made in shades of gray.

addition, sewers and classified by size, but the size of pipes for sewage - an individual matter, is directly dependent on specific needs.

Warming sewer ↑

Insulation sewer pipes
sewer pipe insulation - an important stage

durability and reliability of the sewer communication depends on many factors.Warming of sewer pipes - an important condition.Pipes for external sewage should be warm to cold with a strong water in it does not freeze.The result of freezing can be split pipe or the formation of ice jams, when all the liquid will go out, and it is extremely unpleasant phenomenon.And most importantly, that in the winter are very trudnoustranyaemye problems, so you need to take care of the warming in advance.

iron drain pipe can be insulated by means of laying the heating cable.Watch a video about this process:

High quality pipe - a direct path to a successful operation, but also compliance with the process does not need to be discounted.Today, people are often faced with materials of low quality and, unfortunately, the effects become noticeable after starting the system, when starting failures.To avoid such misunderstandings should buy pipes in specialized stores by requiring sellers certificate.
