Sewer plastic pipes. Characteristics, prices, installation

Sewage plastic pipes gradually replace their less technological predecessors. Today they are quite common in private and industrial construction.

Features of sewer pipes made of plastic

The first and most important property of plastic material for sewage installation is expressed in high quality. Such pipes demonstrate a long service life, but are not very expensive at the same time. In addition, their installation can be done both by a professional in his field, as well as by a home master who does not have an impressive experience in carrying out this type of work.

Sewer plastic pipes do not assume the use of special expensive equipment, and after their installation they do not need repair for several decades. Plastic products for installation of waste systems are distinguished by impressive chemical resistance, after exposure to corrosive media they remain intact. If you follow all the rules when laying, the system will last for 50 years or more, and you can lay out the described material both outside and inside buildings.

Mounting technology

Sewer plastic pipes are laid in a certain sequence. Initially, it is necessary to stock up with blanks of the material, the dimensions of which will correspond to the areas in the room or on the street allocated for installation. After that, you can start laying pipes, connecting them in the process with shaped elements. Once the system is assembled into a single unit, you can proceed to install it on the wall. If a zone has cast-iron pipes, then the plastic bends can be connected to them.

Preparatory work

Sewer plastic pipes can be cut using a hacksaw. But it is recommended to use a special tool which, when cutting, allows you to get a chamfer. When carrying out such work manually, the edge of the product should be carefully cleaned, providing an angle of 150 °, this will eliminate the possibility of failure of the sealing ring.

The installation can be carried out using the following materials and tools:

• Clamps;
• Pipes;
• fitting;
• Hacksaw.

Stacking

The elements must be installed only after a special lubricant has been applied to the smooth end of the components. This rubber gasket will last for a longer time. The smooth edge of the element must be removed from the socket, which will allow the fastening. In order to fix the system, it is necessary to use clamps mounted under the clutch. Horizontally, the pitch between the clamps should not be larger than the pipe diameter tenfold, as for the risers, this distance is approximately 200 cm. The most suitable step from the elements of the system to the pipe is 4 mm. At installation it is not necessary to make fastening rigid, as it can create internal pressure which is inadmissible.

Sewer in the screed and wall

Before you connect the sewer plastic pipes, you should consider whether it may be necessary to conclude the components of the system in concrete. At the same time, one should not miss the moment that the design should have temperature grooves whose width is 10 mm. It is important to reliably strengthen the elements so that they do not change their position. The grooves received between the couplings and sockets should be sealed with a scotch tape.

Pipes sewer plastic, the price of which can vary depending on the parameters, can be laid and in the walls. In the future, they can be hidden under a layer of plaster. In this case, plastic products should be protected, for example, with corrugated cardboard, but glass fiber is also ideal for this.

Conjugation of polymer and cast iron elements

If you live in the construction of the old type, then when changing the sewage system, it may be a problem to make a connection of plastic and cast-iron pipes. Use this requires a transition tube, which has the desired internal diameter. Conjugation of polymer and cast iron pipes is carried out by means of a gasket.

Cost of sewer plastic pipes

Pipes sewer plastic, the price of which varies depending on the characteristics, can have a different bell, the thickness of the walls and the length. For example, products that have a socket 50, are used in the conduct of wiring networks, which are used for household and fecal waste. The area of their application in general is quite wide: they are common for the installation of plumbing fixtures, risers in buildings of any purpose. The pipes described are based on polypropylene in gray. Such material is on average 20 times lighter than analogues made of cast iron. He does not fear the impact of hot water to 95 ^o C, as well as chemicals. Such pipes can have a length of 20 to 3000 mm, and the price varies from 32 to 156 rubles, respectively.

If you need a plastic sewer pipe 100, this means that its diameter is 100 mm, therefore, you can choose products whose wall thickness will be more impressive (2.7 mm), but also the price for the same length that was mentioned above , Will vary within the limits of 65-400 rubles.

Pipes sewer, whose diameter is 100 mm, are designed for mounting outdoor non-pressure systems, through which the sewage is migrated by gravity. These elements are designed for systems that are not subject to significant soil loads.

Before starting the laying of the sewage system, it is necessary to calculate which plastic sewer pipes and fittings you will need, what diameter and characteristics they should have. This will allow you to work on all the rules, which will ensure a long life for the sewage system, and you will be freed from the premature need for repair work.
