Environmental Stress Cracking as a Tool for Evaluating Polyethylene Piping Materials [PE]


Plastic Pipes Conference Association # 1982 York

Lustiger, Markham, Cassady

The phenomenon of environmental stress cracking, which occurs when polyethylene is placed under stress until failure in a detergent environment, is beiag studied both as a means of quality control and for determining the relative resistance to sluw crack growth in polyethylene gas pipe. Two techniques used to measure environmental stress crack resistance (ESCR) for these purposes are presented and discussed.

1985 York : Analysis of Field Failures Caused by Slow Crack Growth

Author(s) : Lustiger

Since 1980, samples of field failures in polyethylene pipe for gas distribution have been collected and analyzed at Battelle in a field failure library. The majority of these failures were found to occur from slow crack growth as a result of a secondary load. Most often, the location of these failures were at points...

In developing optimum polyethylene resins for gas distribution piping, it is important to maximize resistance to slow crack growth (SCG) which is the most common mode of material-related field failure in this application. It is proposed that SCG resistance is related to both tie molecule concentration and the...
