Polyethylene pipes for water transportation are attractive for technical and economic reasons.

Abstract

Polyethylene pipes for water transportation are attractive for technical and economic reasons. However, premature ruptures due to poor quality of the production process or the raw material cast a shadow on this material. The application of PY/GC/MS to the molecular charcterization of polyethylene water pipes is described. The statistical treatment of pyrolysis results allowed to differentiate various groups of pipes. A comparison with conventional polyethylene physical tests is provided. PY/GC/MS showed potential as a tool to estimate pipe quality and hence its resistance against ruptures caused by pressure stress.
