The disadvantage is a lot of weight, because of which construction works are made using special equipment. Also, excessive roughness of the inner surface often becomes a cause of fat and subsequent blockage. Moreover, cast iron pipe for sewer can not be laid in saline soils or used to transport saline solutions.

Polypropylene and polyethylene

Instead, metal pipes lately increasingly mounted plastic systems. They have sufficient strength characteristics, are lightweight, and affordable price. Before you give preference to polypropylene or polyethylene pipes for sewage, is to get acquainted with their advantages and disadvantages.

Technical data and dimensions

Manufacturers offer polypropylene tubes for arranging the inner and outer pipeline. The first type has a single layer structure, moderate strength and resistance against low temperature. The second type - a dual-layer. Consisting of the smooth inside and corrugated outer. Able to withstand the load of the ground. Deformation tube begins at temperature + 150 ° C. Have a density of 0.9 g / cm³. Tensile strength 35 N / mm². Linear expansion coefficient 0.15.

Polyethylene pipes are of limited use. Most often used for the installation of non-pressure sewage systems. In winter, when the liquid freezing inside the pipe, it is not destroyed. It starts to deform when heated above + 132ºS. Density 0.95 g / cm³. Tensile strength 29 N / mm². Linear expansion coefficient 0.19.

Advantages and disadvantages

Polypropylene and polyethylene pipes:

A disadvantage of such products, especially polypropylene, is the sensitivity to UV. This should be considered when choosing a mounting location.

Polyvinyl Chloride

PVC products are widely used in mounting samotochnyh sewage systems. They demand at the device interior and exterior portions. Possess different strength characteristics, and are presented in different sizes. Before choosing the best option is to get acquainted with the available.

Technical data and dimensions

Depending on the method of production of PVC pipes for sewerage are divided into products:

• plasticized PVC (PVC). Have a low cost. Elastic. Different low cost. Demand for installation of individual sections of sewer;
• uPVC (PVC-U). A more expensive option. More rigid and robust products. Able to withstand considerable external influence. Relevant mounting foreign and domestic sewage, including discharge.

Depending on the destination, the pipe for drainage made of PVC can be divided into:

• gray. Sufficiently hard product 32-160 mm in diameter with a wall thickness of 1-3,2 mm. May have a length of 0.3-3 mm. When demand device domestic sewage;
• orange. Possess sufficient strength. Suitable apparatus for the external system. The diameter of this type of product varies between 110-500 mm and a wall thickness of 3 mm and 1.2-3 mm length segments. They have a relatively small coefficient of expansion. Compound of separate elements carried flared manner;
• corrugated. Products of gray have a small diameter. They are used to connect to the sewer dishwashers and washing machines. Orange, consisting of 2 - 3 layers. Essential for mounting the outer system. Can be laid to a depth of 15 m. The high strength provided by numerous stiffeners.

Depending on the strength characteristics of the pipe for drainage of PVC commonly divided into:

• SN 2. Light products. Can be used for drainage device being installed in a relatively small depth, in places through which the road passes;
• SN 4. Average product. Allow stacking at small roads;
• SN 8. Heavy pipes for sewerage, allowing installation under highways and industry.

Advantages and disadvantages

The advantages of this type of sewer pipes may include:

The disadvantage is the elongation when heated. This excludes their use when installing sewers, through which the liquid is transported, heated over 60 ° C.

Asbestos cement and ceramic

For mounting the outer sewer pipes are often used asbestos and ceramics. Such articles have good performance characteristics. Have optimal sizes. Able to withstand considerable loads.

Technical data and dimensions

Asbestos cement pipes for sewer made in accordance with the GOST. For their production, a mixture based on Portland cement, to which is added up to 20% of asbestos fiber. Introduction of this additive has allowed to reduce the weight of the finished product. The diameter of the asbestos-cement pipes varies between 100-500 m. Their length is typically 3-4 m.

Ceramic products have a perfectly smooth inner surface, which is a requirement for pipes used for drainage installation. Suitable for decorating the interior and exterior of the system. Have a transverse dimension of 100-600 mm.

Advantages and disadvantages

The advantages of asbestos-cement and ceramic pipes should include:

Disadvantages include sensitivity to mechanical stress and fragility of products. Most often damaged ends, which can cause great difficulty in carrying out installation works. Ceramic pipes for sewer also have a small length, resulting in a large number of joints.

How to choose the pipe for drainage: the distinctive features of different types of

Before you buy a pipe for drainage, it is necessary to accurately know the location of its installation. From this directly will depend on the requirements for the size and material of which it is made. We offer to meet with the distinctive features of different types of pipes.

external

This type of pipe for sewer is designed for significant operational burden. They have a wall with a large thickness. Resistant to most of the negative factors. The minimum lateral dimensions of 200-300 mm to provide sufficient bandwidth. cast iron, plastic, ceramics, concrete: Various materials are used for manufacturing. The latter received the greatest distribution.

By distinguishing features should include the need for thermal insulation. Even if its technical characteristics the material allows operation at temperatures below freezing, the tube may crack when significant load occurs.

internal

This type of pipe is used to connect to the sewer plumbing fixtures and appliances, for which the water is required. Its main purpose is to divert the effluent into the external drain. Mounted in tight spaces, and therefore has a small cross-sectional dimensions. It is made predominantly of plastic. For the inner tubes is characterized by:

• excellent throughput. The inner surface is performed completely smooth to prevent the formation of soap or body fat, accumulation of garbage;
• low price. They are much cheaper products intended for external system apparatus;
• connectivity via fittings. The latter allows to form various structural elements. Fittings are used for forming the branching pipes or bend at the desired angle.

Pressure

Pressure pipes to acquire systems, the composition of which includes a pump. With it ensures stable operation for several sewer toilets and creates the necessary pressure level in the stand-alone sewer systems.

Availability of the pump leads to a permanent change in the pressure on the pipe. To ensure stable operation of the design, the latter are made sufficiently robust and reliable. Typically, they have a large wall thickness.

Samotochnaya

Used when installing internal drainage and partly external. As a rule, it is set in one-storey buildings. Designed for operation under normal load. Increased not stand.

Attention! Through the use of this type of pipes, manage to significantly reduce installation costs.

How to choose the right size pipes for sewerage: make a choice, given the type and purpose

Inner diameter pipes for sewer can vary within the range 2,5-1100 mm and depends on the location of their installation. Products for domestic use traditional smaller than outer. Since the first diameter is typically 25-110 mm, and secondly 150-1100 mm.

To connect the dishwasher or washing machine to use sewage pipe 25 mm in diameter. To divert water from the sink, shower or bath will require products with transverse dimensions of 3-5 cm. If the sink bathroom, that is, one set for washing machine, sink and shower, the choice is made in favor of a larger diameter. the transverse dimensions individual risers is 7-9 cm.

Products installed outside should be larger, depending on their destination. Pipes for general sewage - at least 15 cm. If the home provides room, a minimum transverse dimensions increase up to 20 cm, and at the swimming pool available - up to 30 cm.

Attention! Pipes with diameter 1.1 m are used when mounting the city sewer.
