In today’s construction market of plastic pipes is gradually replacing metal counterparts. They are made of polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC). The most popular for sewer installation is PVC pipe, which appeared as a more resistant to any aggressive chemicals.
Qualitative plastic sewer pipes have a smooth inner surface on which layers are formed. Installation of the system is done with the help of simple tools. For example, cut the plastic material can be ordinary hacksaw, which leaves no burrs. And if they are formed, they can be easily cleaned.
Than good in the regeneration PLASTIC SEWAGE SYSTEM?
Plastic pipes for sewer made of complex polymer compounds, which are developed using the latest technologies. Therefore, they are strong and durable. Sewer system, plastic can be collected easily and high material costs. With good ductility by applying a heat treatment, they can be easily bent at the desired angle. Drains of these pipes can be easily assembled by hand.
Any kind of plastic pipe has special advantages: Advantages of plastic sewer
reasonable prices;
durability;
resistance to chemical influences, corrosion, aggressive effluents;
low thermal conductivity;
light weight.
Plastic pipes for sewerage are of different sizes, which are determined by the degree of burden on them. Construction of large diameter was originally designed for the increased load. They are used for the construction of sewerage systems in social facilities in apartment buildings, cottages.
For example, hospitals, care for, saunas, hotels suitable pipe diameter of 200 mm. And for the operation of industrial facilities needed plastic sewage pipe with a diameter of at least 300 mm. For the construction of the system in individual residential building will be enough to pave the Communication smaller.
Polypropylene sewer pipes
Polypropylene pipes are made, which are used in pressurized water and sewage systems.
FEATURES sewer communications POLYETHYLENE
Sewer plastic pipes made of polyethylene – the material is absolutely resistant to alkaline and acidic environments. It will serve as proof that in plastic containers can be kept acidic electrolytes for battery charging, as well as alkali, intended for cleaning sanitary ware.
Polyethylenes are not afraid of low temperatures. Tubes of this material are stretched only during freezing, but after the ice plug melts, the construction takes the original dimensions.
The inner surface is smooth polyethylene tubes, so it hardly deposits accumulate.
The only drawback of plastic communication – it’s a bad resistance to high temperatures. Still, some brands of polypropylene can withstand up to 80 degrees. Recently, the industry produced products from cross-linked polyethylene. They can withstand temperature conditions of up to 200 degrees.
Polyethylene corrugated pipes
Corrugated pipes made of polyethylene two-layer material. They are used for installation of external sewage. Corrugation made of high-quality brand of polyethylene PE80, PE63 or brand. Material deeply resistant to chemical influences. Corrugated sewer communications, due to its ring stiffness, can be laid to a depth of one meter to twenty.
Dimensions of plastic sewer pipes made of polyethylene are determined in accordance with GOST 22689.2-89. According to the standard products are provided with a diameter of 40 mm, 50 mm, 90 mm and 110. And according to the standards under the number 18599-83 made of polyethylene pressure pipes from 10 cm to 120 cm. Construction of more than 160 mm in diameter made from lengths of 5 to 12 meters, and sewage pipes of smaller diameter can be produced segments, in coils or coils.
PIPES Plastic sewage from PVC and PVC-U
UPVC pipes made from unplasticized polyvinyl chloride. This is quite a hard material is resistant to all acids and bases, has a high hardness and strength. In addition, it is resistant to gasoline, oil, alcohols, aliphatic carbohydrates and many other corrosive substances. UPVC pipe wall can withstand very high loads.
Rigid PVC-U pipes are divided into two groups. Construction class SN4 can be laid where there is not much traffic, and class SN8 pipes are suitable for laying pipes in areas with large traffic flow. Sewer pipes, PVC-U can not be used at the hot effluent of more than 60 degrees.
PVC pipes, plastic (PVC) is widely used for laying sewer networks. Push-fit connection is made by using a rubber cuff.
Features sewer pipes UPVC and PVC:
Full frost. During freezing the material does not crack.
Lightweight and quite easy system integration.
wear resistance
Tubes are stable when exposed to alkalis, acids and mineral oils.
Not prone to fire, and at a temperature of 120 degrees begin to decompose, releasing carbon dioxide.
Plastic pipes of PVC – enough elastic and tough material, but when mechanical loads and large excesses able to break.
PVC products are not suitable for transporting high flows. They are easily deformed even at a temperature of 60 degrees.
PVC sewer pipes are manufactured according to GOST P 51613-2000 for a number of appropriate sizes: diameters from 10 mm to 315 mm. The length of the product is from 4 meters to 12 to the structure of PVC are standard sockets and rubber seals, which are necessary for the installation of sewerage systems.
FEATURES installation and laying PLASTIC SEWAGE
Plastic pipe for sewerage not able to absorb vibration and acoustic vibrations, such as iron. Plastic – it is light and thin material. Cast articles quenched sounds due to its weight, and plastic structures perform the function of the resonator.
Most passed vibration and noise of the PVC pipe, to a lesser extent – polyethylene. Thus, when installing the system, sewer pipes must be covered with plastic sound insulating material or stretching them in a box.
When Spike cropped pipe socket, you need to clean up the design. Any irregularities that will remain on the inner wall of the pipe will be collected from waste solids.
If the connections are joined with effort, you can use any lubricant: grease, glycerine, any soap.
When installing the sewer pipe system of plastic coming from the home stretch with a slight slope (1-2 cm. Per meter of pipe), then drains into the sewage will not be delayed. Fixing pipes comes with clamps and clips.
When assembling the riser clamp is necessary to fix the neck of each tube. If the compensating nozzle is mounted, it is fixed in the same manner.
Do not expect to please that plastic pipes enough sealing rings. Over time, they become loose, and joint space can develop leaks.
Since plastic pipes have a tendency to sag under its own weight, the horizontally located tubes of 110 mm diameter and up to be fixed hangers and clamps at a distance of not less than one and a half meters.
If the planned laying of plastic sewer under the highway, the pipe should be laid to a depth of not less than one meter. If possible, do not allow to bury, they will need to reach in reinforced concrete box.
To clean the sewer risers usually used steel wire, which is not suitable for plastic construction. Wire can be very scratch inner plastic wall. Therefore, it is more expedient to use a soft wire, which is protected at the end of a rubber tip. The easiest method to clean the plastic drains without damaging the inside of the pipe, disassemble connection and remove the blockage.
