Pipes for sewerage - types and characteristics, specific differences

Pipes for sewerage

Pipes for sewerage - items without whichtoday it is impossible to imagine any one comfortable accommodations. What is sanitation and the importance of its full functionality, known and understood by everyone. But still the question remains, what is best for sewage pipes, because of their wide range, and the sewage system must be reliably and accurately.

Modern alternative to outdated pipe rolling

Waste and dirty water discharged by the sewerage system, which in turn is divided into external and internal. internal sewerage system is one of the most necessary todayutilities. 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 replacing sewer pipes is extremely relevant today, and it is not surprising, modern lines have indisputable advantages:

- The absence of electromechanical corrosion;

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

- Labor saving (2-3 times)

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

Types of sewer pipes

Firstly, the sewer pipe are divided into two main types: cast-iron and plastic, that is, depending on the material.

Iron - the traditional solution

Cast iron pipes for drainage 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.

Tubes made of cast iron

Cast-iron sewer pipes

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

Moreover, the inner surface is characterized byroughness, and thus 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, since the production of this metal is not cheap.

Plastic pipes, priorities

Plastic pipes for sewage systems provide the functionality of the communication quality. Apply these pipes for domestic sewage and outdoor.

Plastic pipes for domestic sewage

Plastic pipes for sewer internal type

They have a number of advantages:

  • smooth surface creates favorable conditions, so that the pipes do not form blockages;
  • light weight - an excellent result fortransportation and installation. When installing special equipment is not in use, sealing solution - plastic pipe is simply inserted into the socket of another pipe, with O-ring of high-quality rubber, which provides a seal for many years. Alternatively, installation is carried out with the help of fittings;
  • low cost in comparison with steel and cast iron;
  • long service life.

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

Plastic sewer pipe outdoor sewerageAnd internal including made of three kinds of plastic: High density polyethylene, PVP briefly, polyvinylchloride - PVC and polypropylene - PP.

PVC Pipes

PVC pipes for sewage systems are used in moredegree of gravity sewer type. They are resistant to ultraviolet light, and a low coefficient of linear expansion is ideal for sewage purposes. PVC pipes are characterized by high strength and good resistance to mechanical damage, as well as run-off is held with 70-degree temperature. But the fact of exposure to chemicals, aggressive detergents and high temperature liquids negatively affects the condition of pipes, damaged walls and there is a plaque, which eventually turns into a blockage.

polyethylene pipes

Polyethylene pipes for seweragedesigned for internal and external pressure pipelines. They are the most heat sensitive and are subject to expansion under the influence of high temperatures. - 40 ° C to + 40 ° C - Low operating temperature range of polyethylene pipes, so their use is not recommended for sewer drain with hot water.

Pipes for sewer Polypropylene

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

Piping for drainage of storm type

Flexible corrugated pipe

Corrugated pipe stormwater

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

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

Pipes for external sewage

Plastic pipes - great sewer devices

In addition, the sewer pipes and are classified by size, but the size of the pipe for drainage - an individual matter, is directly dependent on the specific needs.

Warming sewer

Insulation sewer pipes

Insulation pipe sewage - an important step

The durability and reliability of the sewercommunication depends on many factors. Warming of sewer pipes - an important condition. Pipes for external sewage should be warm, so that when a strong cold water in it does not freeze. The result of freezing can be split pipe or the formation of ice jams, then 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.

High quality pipe - a direct path to successoperation, but also adherence to the process do not need to be discounted. Today people are often faced with poor quality materials and, unfortunately, the effects become noticeable after system startup, when failures start. To avoid such misunderstandings, sewer pipes must be purchased in specialized stores by requiring sellers certificate.
