Markings polyethylene pipes and their properties

brief definition of what is a PE and SDR pipe.

To understand the marking of polyethylene pipe, it is necessary to know that the value of the SDR - is the ratio of the external diameter of the pipe (DB) to the thickness of its walls.That is, if the SDR rate increases, then the product becomes thinner wall or on the contrary, the smaller the SDR rate, the thicker the wall.

Now, define value with PE.This option in the marking is nothing more than a polyethylene, but the figure that follows it indicates the mark of this polyethylene.

To date, the most commonly used brand of PE 100 and PE-80.Of course, the pipe with one or another material has its own idiosyncrasies.Consider the main ones:

1. Applying PE 100 weld will be more uniform.This is achieved due to the fact that such a tube is characterized by its crystalline lattice structure.
2. grade PE 100 pipe more durable and cheaper.

Main features of PE pipe 80 with a different parameter SDR.

consider the main characteristics of this product:

• PE 80 SDR 21 - the low pressure pipe.It is used when installing a gravity sewer or slabonapornoy.
• PE 80 SDR 17 - SDR 17 pipe is characterized by the average of d in the pipe wall thickness.It is used for drinking water supply, irrigation systems, etc.The best option for low-rise houses.
• PE 80 SDR 13,6 - low-pressure pipe.Most often they are used for ordinary transport of cold water.

Main features of PE 100 pipe with different parameter SDR.

consider the main characteristics of this product:

• PE 100 SDR 26 - pipe bearing the label used for the transportation of drinking water as a business or in the country as well as in urban areas.They are characterized by high density, strength, and resistance to cracking.They are lightweight and well suited for mounting plumbing or for transporting various foodstuffs in liquid form (for example, juice, wine, milk, etc.).
• PE 100 SDR 21 - pipes used in the construction of water pipelines, as water passes over them, does not acquire odors and preserves its taste.Yellow bar in the pipeline means that its use is recommended for the installation of gas systems, and blue - for water.
• PE 100 SDR 17. Pipes marked SDR 17 belong to the new generation.Has high strength and enhanced performance.SDR 17 are ideal for pipeline installation and pressure water systems.
• PE 100 SDR 11 - well pipes withstand high pressure.Differ high environmental safety and water quality.Have chemical resistance, so stacking is possible in any kind of ground.

Pipe PE 100 SDR 17 as the best option.

pipeline with a value of SDR 17 is ideal for the installation of pipes with large cross-section.The savings in the manufacture of this type of pipe, is essential due to the possibility of reducing the wall thickness of the indicator.Thus, the product retains its high strength characteristics.Technical parameters of the pipe SDR 17 allow the use of this product in the construction of piping systems with long.

We have given the basic characteristics of pipes with labels containing the values ​​of PE, and SDR.Mark polyethylene pipe considerable influence on the quality of the final, finished product, so when buying, consider this factor.
