Statistical analysis of HDPE fatigue lifetime
ical properties throughout a HDPE gas pipe wall. The variability of mechanical properties within the pipe wall revealed the complexity of hierarchical structure in HDPE and such an approach is intended to con-tribute in understanding pipe long-term behavior and associated brittle failure. Unfortunately, the large majority of HDPE fatigue
Reliability-based assessment of polyethylene pipe creep
Reliability-based assessment of polyethylene pipe creep lifetime. is defined as the hoop stress that, when applied continuously, will cause the failure of the pipe at 10 5 h (11.4 years). This strength determines the design lifetime for thermoplastic pipes. For the considered HDPE pipe …

Plastic Pipe Facts
Finally, Carollo Engineers reviewed the existing literature in 2007 and their investigations also found that premature aging of HDPE in potable water lines was a failure mode which was not well understood in the US, but should be addressed by the relevant pipe standards. 19 Carollo found that HDPE oxidation in water disinfectant environments is
HDPE pipe - WikiMili, The Free Encyclopedia
HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high press
HDPE : The Complete Buyer''s Guide - Provident Procurement

Hamilton to replace water mains in Highland Park neighborhood
An entire town in France installed HDPE pipes, “and they had failures in as short as one year,” he said. Meanwhile, the average age of city’s water mains overall is about 75 years, Logan said.
Plastic Pipe Facts
Reports of HDPE water pipe failures have linked the failures to oxidative degradation. The two largest water utilities in the world, Veolia Environnement and Suez Environnement experienced a rash of HDPE service line failures – which were initially thought to be ductile in nature (warmer soils can soften plastic pipe causing bursts).

Failure Analysis of HDPE Pipe for Drinking Water
The principal objective of this work is to analyze the severity of defects on high density poly-ethylene pipe widely used for water piping networks. An experimental program, including longitudinally notched (125 mm) PE100 pipe specimens with 11.4 mm thickness containing an external notch with four different notch depths (a), was developed.
HDPE For Drinking Water Pipes
• 19 failures in 2009 on a total PE100 network of 800 km result in an average failure rate of 2.4 failures /100 km and year • A low failure rate of 9.4 for the total pipe grid is still significantly higher than the rate of 2.4 just for the PE part.
Ductile iron pipe - Wikipedia
Ductile iron pipe is a pipe made of ductile cast iron commonly used for potable water transmission and distribution. This type of pipe is a direct development of earlier cast iron pipe, which it has superseded. The ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron.
