What is the meaning of the designations PE80, PE100 & PE100-RC?

PE80 and PE100 meaning The designations PE80 and PE100 are based on the long-term strength of the respective materials, known as the minimum required strength (MRS) in accordance with ISO 12162 . The designations are: Material Designation Minimum Required Strength (MRS)MPa PE100 & PE100-RC 10.0 PE80 8.0 Minimum Required Strength (MRS) The MRS is determined by performing  regression analysis in accordance with  ISO 9080 on the test data from the results of long-term pressure testing. The...

HDPE PE100 & PE100-RC Pipe: Properties and Types

HDPE PE100 & PE100-RC Pipe PE100 is the third generation of pipe grade PE . It has an optimum balance of three key properties: Minimum Required Strength (MRS)   – this provides long-term strength and creep resistance. Stress crack resistance   (sometimes referred to as slow crack growth resistance). Rapid crack   propagation resistance. HDPE   PE100 pipe is easy to install, light, flexible, corrosion-free and has a service life of up to 100 years. It can be jointed using butt fusion or...

How do these designations relate to MDPE and HDPE?

Prior to the adoption of international standards (CEN, ISO) PE pipe materials were more commonly designated by their density within the range associated with PE i.e. Low Density PE (LDPE), Medium Density PE (MDPE) and High Density PE (HDPE). The reference to density gave an indication of the material strength. For example HDPE pipe had a higher long term strength or minimum required strength (MRS) than LDPE. But this gave no indication as to other long term properties, such as slow crack...

Are any special pipes available for specific applications?

Yes. The PE pipe producing industry is very innovative in developing pipes for special applications and to be more cost-effective in dealing with installation and service needs. The special pipes are mainly multi-layer materials. These are co-extrusions of different thermoplastic materials to form pipes with two or more layers in their walls, with each layer performing a specific function. The multi-layer pipes may have: A harder thin outer layer to protect the main body of the pipe from...

What test methods are used to measure the properties of PE100 pipe?

There are standard test methods for all the key characteristics and properties of PE100 pipe. These are mainly ISO and EN methods. The PE100+ Association requirements for Creep Rupture Strength, Stress Crack Resistance and Rapid Crack Propagation Resistance are the same as or greater than those in the EN/ISO Standards.
