Series: ASM Failure Analysis Case Histories
Publisher: ASM International
Published: 01 June 2019
DOI: 10.31399/asm.fach.chem.c0090454
EISBN: 978-1-62708-220-4
... Abstract A chemical storage vessel failed while in service. The failure occurred as cracking through the vessel wall, resulting in leakage of the fluid. The tank had been molded from a high-density polyethylene (HDPE) resin. The material held within the vessel was an aromatic hydrocarbon-based...

... Abstract A high-density polyethylene (HDPE) natural gas distribution pipe (Grade PE 3306) failed by slow, stable crack growth while in residential service. The leak occurred at a location where a squeeze clamp had been used to close the pipe during maintenance. Failure analysis showed that the...

.... These effects are summarized in the schematic creep rupture curves of Fig. 1 . High density polyethylene exhibits ductile failure (elongations to break of several hundred percent) at stresses near to its reported yield stress. At lower stresses and longer failure times, a different molecular mechanism...
