Each person will most likely have to deal with laying or replacing sewer pipes, so you need to know the nuances of their choice. Here we will consider the main characteristics of sewer products - pipe sizes, and also pay special attention to PVC as a manufacturing material.
Sewer pipes are produced in accordance with TU 2248-022-23208482-02. Today's sewer market is filled with products of all sizes. The most important characteristics are diameter, length and wall thickness.
Let's consider some pipe sizes (i.e. diameter) for sewerage.
| Nominal pipe diameter (Dy) mm | Thread diameter (G), inch | Outer pipe diameter (Dn), mm | ||
| Steel gas pipe | Seamless | Polymeric | ||
| 10 | 3/8 | 17 | 16 | 16 |
| 15 | 1/2 | 21, 3 | 20 | 20 |
| 20 | 3/4 | 26, 8 | 26 | 25 |
| 25 | 1 | 33, 5 | 32 | 32 |
| 32 | 1 1/4 | 42, 3 | 42 | 40 |
| 40 | 1 1/2 | 48 | 45 | 50 |
| 50 | 2 | 60 | 57 | 63 |
| 65 | 2 1/2 | 75, 5 | 76 | 75 |
| 80 | 3 | 88, 5 | 89 | 90 |
| 90 | 3 1/2 | 101, 3 | 102 | 110 |
| 100 | 4 | 114 | 108 | 125 |
| 125 | 5 | 140 | 133 | 140 |
| 150 | 6 | 165 | 159 | 160 |
The universal type of pipe has a diameter of 75 mm, its purpose is to drain wastewater from free-standing sanitary ware (sinks or bathtubs). But it is most likely not suitable for toilet bowls, since it may not withstand such a load. To drain sewage from the toilet, sewer pipes of at least 100-110 mm in diameter are used.
To transport sewage from the bathroom, a pipeline 90 mm in diameter is used. "Where are large pipe sizes used?" - you ask. Yes, everything is very simple, they are used to mount risers and lay sewer outletsfar beyond the structure.
When choosing a product from those on the market, keep in mind that the parameters of tubular products are related, so you need to clarify the required characteristics. For pipe products with large diameters, the wall thickness is appropriate. For example, a diameter of 150-160 mm corresponds to wall 3, 9, and a diameter of 110 mm corresponds to 3 mm.
Not only the weight, but also the amount of material used depends on the diameter indicators. So, a running meter of a pipe with a diameter of 110 mm slightly exceeds the figure in kilograms, while a pipe with a diameter of 160 mm already weighs more - up to two kilograms.
Important! When diverting the yard sewer, a material with a diameter of 300 mm is used.
PVC pipe dimensions
The advent of polyvinyl chloride was a leap in construction technology. Now the material is moving towards glory with leaps and bounds, displacing known materials from everyday life. Cast iron, steel and ceramics began to lag behind the new, more advanced version. In addition, all sizes of steel pipes were made from a new material. The advantages are visible: low cost, long service life, lightness and environmental friendliness.
With the help of modern technology, it is possible to produce pipes of different sizes, taking into account the wishes of the buyer. Such an advantage will be needed for the work of specialists, and an ordinary person will not be able to understand all this. When looking at the label when choosing a material, it is worth remembering that only the size is indicated there.outer diameter, and its inner value must be determined by subtracting the wall thickness. The dimensions of polypropylene pipes should be selected in accordance with the role and load assigned to them.
The big advantage of this type of pipes is the ability to easily cut them into pieces with an ordinary grinder. Thanks to this quality, installation is often simple and does not require special skills and experience.
