Plastics Pipes in Water Distribution Systems. A Study of Failure Frequencies [PE, PVC]

Standardisation, Certification & Recycling # 1992 Eindhoven

Investigations of failure frequencies in municipal water distribution networks have been performed on several occasions over the past 15 years in Sweden. In a follow-up study, reasons for failure in PVC and PE water pipes during the period 1986-1990 have been studied. It was found that PVC pipes manufactured after -73 have significantly improved failure frequencies compared with pipes manufactured before this date. Pipe failures are rare for PE pipes in general and for PVC pipes manufactured after 1973. Joint failures are 2-4 times more frequent than failures in the pipe itself. The study indicates that for modern PVC and PE pipes, it is probably possible to achieve a failure frequency of around or below 0,l failures/lO km,year which is roughly 10 times less than the average failure rate recorded for the current Swedish distribution network.

Installations of solid wall HDPE pipes are becoming more difficult and riskier with the increase in diameter (OD2000+ mm), length of strings (1000+ meters) and reduction in the wall thickness (SDR26-30). To gain a better understanding of the limits of the final pipe assembly prior to the sinking, a laboratory tests in...

The S-bend installation method is the reason for the successful worldwide development of the market for marine PE pipelines over the last 50 years. Small and medium sized PE pipes can safely be installed using the S-bend installation method; however, difficulties increase as pipe sizes increase. In order to ensure a...

The performance of buried large diameter structured wall PE pipes has been studied by following the development of the deflection in four different large diameter PE pipes installed in Finland and Sweden. The pipes studied have had an internal diameter of 2000-2400 mm and a ring stiffness of 4-8 kN/m2. Two of the...

An old 1550 mm diameter heavily corroded water pipe, was in March 2003 relined in Kolkata, India by using 1400 mm SDR 30 PE pipework. In all, 1 km of pipe was rehabilitated. To facilitate the installation of the PE pipe and maximize the insertion lengths, extensive planning for a slip-lining operation was carried out....
