Color sewer pipe
Practically in every building there is a drainage system, that is, sewage. Many are faced with the need to update or replace pipes, and, accordingly, self-procurement of materials. Therefore, it is important to consider that the color of sewer pipes differs, depending on their purpose and application. From this article you will learn for what purpose the palette of sewer pipes is used.
Kinds
The system of discharge of waste products is divided into 3 categories:
- Internal network - serves to collect waste inside the building.
- Outdoor network - formed to collect and deliver fluids to the sewage treatment system.
- The system of surface runoff - it provides the collection of rainwater and melt water, and its transportation to the receiving water.
In addition, the pipes are divided into non-pressure and pressure.
Materials
It is worth paying attention to the material from which the pipes are made.
PVC products (polyvinyl chloride) can withstand a temperature load of 95? C for a short time. The optimum temperature of liquids for such pipes should be no more than 60? C.
PP pipes (polypropylene) can withstand prolonged exposure to liquids with temperatures up to 95? C. In addition, they are non-flammable due to the flame retardants contained in the composition and are highly resistant to aggressive substances.
The palette of pipes drainage systems
The color of the pipes depends on the place of application. This is a very good idea of the manufacturers: mark the pipes with color. It facilitates the choice of consumers, because not everyone understands the features of these products at a professional level.
For example, gray pipes are used for the internal system, but sometimes white pieces are found in stores. They are used in the event that gray products do not fit into the interior of the room. There are no qualitative differences between gray and white pipes. All components of the corresponding color are produced for both colors.
Pipes for external sewer systems are orange or brown.
Tip! Pipes for drainage and drainage of rainwater are also green or blue.
You can find sewer pipes in black, but quite rare. They are used for both external and internal wastewater collection system.
Some manufacturers make pipes with high sound insulation for domestic sewage.
Tip! According to GOST, the color of the pipes is not regulated, but manufacturers strictly adhere to the above color marking.
Gray and white tubes
For the installation of an internal sewage system, gray pipes are most often used. The diameter of these pipes can be from 32 to 150 mm, length from 150 to 5 000 mm. At the edges there are sockets, thanks to them the pipes are interconnected. For ensuring tightness sealing rings (elastic bands) are used.
Pipes for domestic sewage single-layer. The pipe wall thickness is 2.7 mm. It can withstand temperatures up to 95? C. This means that it can safely withstand draining hot water from dishwashers and washing machines.
Tip! These pipes are chemically resistant to aggressive substances, so they can be used for installation of drainage systems in chemical laboratories and hospitals.
Polymers from which gray sewage pipes are produced also have good sound insulation. When choosing sewer pipes, it is necessary to consider whether a pump will be installed for sewage. In this case it is necessary to use pressure gray or white pipes.
Orange and brown
To form a system for diverting wastewater outside the building, use pipes of bright orange or brown color. The diameter of these products varies from 110 to 150 mm, length from 500 to 2000 mm.
Orange pipes are produced in two types: single layer and multilayer.
Single-layer pipes are divided into two classes:
- SN4 - wall thickness is 3 mm. This class is used to form a system for the discharge of effluent at a depth of 0.8 to 6 m.
- SN8 - wall thickness 3.2 mm. It is used for sewers laid at a level less than 0.8 m or deeper than 6 m from the surface.
Double-layer pipes are used for laying the sewer system at a great depth. The outer layer is a corrugated pipe, it provides additional rigidity. The inner surface is smooth, it allows fluids to move freely.
Tip! The pipes made on technology Multi-layer, have an intermediate layer. This is a foam mass of NSAID, it reduces the mass of the pipe while increasing the level of technical and operational characteristics.
Green and blue
Blue pipes are most often used for laying rain and melt water discharge systems inside heated residential and industrial buildings.
These pipes are incredibly durable. Because the risers and drainage pipes must withstand the pressure of water flow during blockages and overflows of the system. This pressure depends on the height at which the water intake funnel is located.
PVC sewer pipes are not laid under highways. Despite the strength of this material, deflection, displacement or change in slope occurs. And this inevitably leads to stagnation and blockage of the system for drainage.
Black pipes
These products are somewhere between gray and orange pipes. Make them from polymers of a high pressure. Apply to free-flow (gravity-free) systems, with a temperature load of not more than 60? C. The immersion depth of the pipes does not exceed 80 cm. But they are resistant to aggressive chemicals.
These pipes are rarely used as an independent product. Most often they are used as a cable channel. Well, if there is a perforation, then they can be an excellent part of the drainage system.
