The meaning of PE100 pipe
PE materials are classified into five grades according to international standards: PE32 grade, PE40 grade, PE63 grade, PE80 grade and PE100 grade.
The PE pipes we use for water supply pipelines are high-density polyethylene (HDPE), and their grades are PE80 and PE100 (abbreviated as MRS, which stands for Minimum Required Strength). The MRS of PE80 reaches 8 MPa, and that of PE100 reaches 10 MPa (MRS refers to the strength of the pipe under circumferential tensile stress).
PE80 refers to the 80th grade polyethylene raw material, and 100 is the 100th grade polyethylene raw material. Correspondingly, the pressure-bearing capacity of the 100th grade is superior to that of the 80th grade. When made into PE water supply pipes, the maximum pressure-bearing capacity of the 80th grade is 1.25 MPa, while that of the 100th grade is 1.6 MPa. The density of the 80th grade is lower than that of the 100th grade, so the 80th grade is called medium-density polyethylene (MDPE), and the 100th grade is called high-density polyethylene (HDPE).
Under the same operating pressure, PE100 grade pipes are thinner and lighter than PE80 grade pipes, which reduces engineering costs and construction expenses. Through the comparative analysis of PE100 and PE80, using PE100 material instead of PE80 is a trend. Since the prices of the two raw materials are close, as the usage of PE100 material continues to increase, even for small-diameter pipes, the material can be replaced by PE100 instead of PE80.
Of course, due to the inherent characteristics of PE materials, whether using PE100 material or PE80 material, protecting the pipes and preventing external force damage is always an important task. At the same time, when connecting different series of pipes, fittings, and valves, proper transitions must be made.
PE100 refers to high-grade polyethylene pipes that meet international standards:
• High-density polyethylene material with an MRS value of 10 MPa
• Offers superior mechanical properties and a longer service life compared to lower-grade products
PE100 is a classification designation for polyethylene pipe materials, indicating that the pipe is made from the highest grade of high-density polyethylene (HDPE) raw material.
Detailed meaning explanation:
1. "PE" represents polyethylene (Polyethylene) material.
2. The number 100 indicates that the minimum required strength (MRS) of the material is 10 MPa (according to the ISO12162 grading standard).
3. Performance features:
• Higher long-term static hydraulic strength
• Better resistance to slow crack growth
• Superior anti-fast crack propagation performance
4. Application advantages:
• Capable of withstanding higher working pressure (typically up to 1.6 MPa)
• Can reduce wall thickness by approximately 30% compared to PE80 under the same pressure
• Service life can reach over 50 years
