What does PE100 refer to and how is PE pipe graded?

September 10, 2024

‌HDPE pe100‌ refers to high-density polyethylene pipes with a raw material density of 100 for pipes. This type of pipe complies with ISO 4427 and EN12201 standards, and has the characteristics of high-density polyethylene, namely, a large molecular weight and a density greater than 0.94g/cm3, as well as excellent impact resistance, aging resistance and corrosion resistance.

PE100 refers to a grade of high-density polyethylene (HDPE) material.PE stands for polyethylene, and the number 100 represents the material's minimum tensile strength of 10 MPa, indicating that the material has excellent mechanical properties and durability.PE100 is one of the most common and widely used HDPE materials on the market today.

PE pipe is a kind of pipe made of high-density polyethylene, which has many advantages, such as corrosion resistance, lightweight, flexible, easy to install and maintain. In order to meet different engineering needs, PE pipes are graded according to their material properties and specifications.

What does PE100 refer

The grading of PE pipes mainly includes the following aspects:
1. Pressure rating: PE pipes are graded according to the maximum working pressure they can withstand. Common pressure ratings are PN6, PN8, PN10, PN12.5, PN16, etc., the larger the number indicates that the pipe can withstand a higher pressure.
2. Size specifications: PE pipes are graded according to their outer diameter and wall thickness. Common size specifications are DN20, DN25, DN32, etc., of which DN indicates the nominal diameter of the pipe, the larger the number indicates the larger the diameter of the pipe.
3. SDR Ratio: SDR is Standard Dimension Ratio (SDR), which indicates the ratio of the pipe's outside diameter to its wall thickness.The smaller the SDR value, the greater the wall thickness of the pipe and its ability to withstand pressure. Common SDR values are SDR11, SDR17, etc.
4. PE material grade: PE pipes are graded according to their material properties. In addition to PE100, there are also grades such as PE80, PE63, etc. PE100 material has higher tensile strength and corrosion resistance, so it is more commonly used in engineering.
The grading of PE pipe allows you to choose the right pipe material for different needs and applications. For example, for some projects that need to withstand higher pressure, choosing PE pipes with PN16 or higher pressure rating is appropriate. For some pipes that require larger diameter, choosing PE pipes with larger size specification is necessary.

Features and applications

The main features of PE100 grade pipes include high temperature resistance, low temperature resistance and pressure resistance, and are suitable for applications in different environments and working conditions. This type of pipe is widely used in the field of water supply, such as HDPE pipe for water supply in urban water supply systems, rural tap water projects and industrial water pipeline projects. Due to its good pressure resistance and corrosion resistance, it can ensure the safety, reliability and long service life of water supply pipelines.

PE100 grade pipes also have good corrosion resistance and aging resistance, and can be used for a long time in humid, acidic and alkaline environments without being easily affected by corrosion or aging. In the field of drainage, PE100 grade pipes also perform well, and their smooth pipe walls are not prone to scale accumulation, ensuring the patency and cleanliness of the drainage system.

In the field of gas transportation, PE100 grade pipes also have important applications, mainly used in urban gas transmission pipelines, liquefied petroleum gas (LPG) transmission pipelines and industrial gas pipeline networks.
