A brief definition of what a PE and SDR pipe is.
In order to understand the marking of a polyethylene pipeline, it is necessary to know that the value of SDR is the ratio of the outside diameter of the pipe( dv) to the thickness of its wall. That is, if the SDR is increasing, then the product wall is thinning, or vice versa, the smaller the given SDR, the thicker the wall.
Now, let's define the PE value. This parameter in the labeling means nothing else than polyethylene, but the figure that follows it indicates the brand of this polyethylene itself.
To date, most often used brand PE-100 and PE-80.Of course, the pipe from a particular material has its own distinctive features. Consider the main ones:
- Applying the PE 100 welding seam is more uniform. This is achieved due to the fact that such a pipe differs in its structure of the crystal lattice.
- Pipe brand PE 100 is stronger and cheaper.
The main characteristics of the pipeline from PE 80 with a different parameter SDR.
Consider the main characteristics of this product:
- PE 80 SDR 21 - low pressure pipe. Used for installation of non-pressure or low-pressure sewerage.
- PE 80 SDR 17 - the SDR 17 pipe is characterized by its average dd of pipe to wall thickness. It is used for supplying drinking water, irrigation systems, etc. The best option for a low-rise building.
- PE 80 SDR 13,6 is a low-pressure pipe. Most often they are used to transport ordinary cold water.
The main characteristics of the pipeline from PE 100 with a different parameter SDR.
Let's consider the main characteristics of this product:
- PE 100 SDR 26 - pipes with such marking are used for transportation of drinking or domestic water both in the city and in urban conditions. They are characterized by high density, strength, and also resistance to cracking. They are light in weight and are excellent for installation of water pipes or for transporting various food products in liquid form( for example: juice, wine, milk, etc.).
- PE 100 SDR 21 - pipes are used in the construction of water pipes, because water, passing through them, does not acquire an extraneous smell and saves its taste. The yellow strip on the pipeline means that its use is recommended for the installation of gas systems, and the blue one for water pipelines.
- PE 100 SDR 17. Pipes labeled SDR 17 refer to the new generation. They have high strength and enhanced performance characteristics. SDR 17 is perfect for gas pipelines and installation of pressure water supply systems.
- PE 100 SDR 11 - the pipes can withstand high pressures well. They are distinguished by high ecological safety of water and quality. They have chemical stability, so laying is possible in any kind of soil.
Pipe PE 100 SDR 17, as the most optimal option.
The pipeline with a value of SDR 17 is ideal for pipe installation, with a large cross-section. The savings in the manufacture of pipes of this type are significant due to the possibility of reducing the wall thickness index. In this case, the strength of the product retains its high characteristics. Technical parameters of the SDR 17 pipe allow this product to be used in the construction of pipeline systems with a long extension.
We have listed the main characteristics of pipes with markings containing PE and SDR values. The mark of the polyethylene pipeline significantly influences the quality of final, finished products, therefore, when buying, consider this factor.
