What is the typical design life of PE pipe ?
PE pipe systems are usually designed by our customers based on empirical and actual test data on the basis of a 50 year service life. Under normal operating conditions the actual life is expected to be considerably greater. Plastic pipes are made from visco-elastic material which means the tensile or hoop stress capacity varies with time. Long term strength is determined by the results of long-term pressure testing and performing regression analysis on the test data. This gives the design...
TEPPFA PE100 Position on 100 years lifetime expectancy of PE Pipes
100 years lifetime of Polyethylene pressure pipe systems buried in the ground for water and natural gas supply
985 Kilo bytesWhat factors can influence the design or service lifetime?
The service lifetime is influenced by five factors: The pipe operating conditions (temperature and pressure) The pipe material used External pipe loading (traffic loading, high water table, etc.) The surrounding environment, including the chemical loading from, for example, contaminated soil. Installation conditions and methods As an example, for design purposes the MRS is specified at a nominal temperature of 20°C. Many buried pipelines, particularly in Europe, operate at temperatures...
