Case study 4 Practical experience with sewer pipes

 

Case Studies, Discussion & Buyer's Guide # 1972 Southampton

In the Nordic countries common research work concerning buried sewer plastics pipes has been followed by an independent evaluation group led by the authors. This group was founded in 1968 by the Nordic plastic industries in order to create a forum for independent evaluation of all the various research programmes so as to achieve a basis for common standard specifications.

The evaluation group, which consists of two representatives from each of Denmark, Finland, Norway and Sweden, had its first seminar in December 1968. As far back as that occasion the theory of ~olin'?, concerning the behaviour of thin-walled flexible pipes buried in the ground, was accepted as a basis for a standard proposal. Since then three additional seminars have been held, the last of which, in Stockholm in May 1972, was also the final one. Reports are available from all seminars. A summarising interim report in English was presented at an IS0 meeting in Frankfurt in April 19703, and a verbal report was also given by Molin at the first Southampton Symposium in 1970 ...

When performing strength quality control of PE pressure pipes made of new grades it is important to take the creep vs. time into consideration and not only the common stress vs.time behaviour. Thus, it is just the relation between linear strain and logarithmic time, which will within a reasonable testing time help us...

Author(s) : Janson

New research and development particularly concerning the long-term strain of modern PE resins have created a basis for a simple and adequate method for tightness testing of plastics pressure pipelines. Thus, it is shown that for plastics pipes subjected to constant internal hydraulic pressure, it is quite possible to...

1992 Eindhoven : The Actual Performance of Plastics Pipes in Europe over 25 Years

Author(s) : Elzink, Molin

Today, in some parts of Europe plastics pipes and fittings are considered as mature products which have obtained an established position in underground applications. However, in others due to their flexible nature, their use is still sometimes questioned. This paper describes the actual performance of plastics pipes...

1988 Bath : Physical Ageing of Buried PVC Sewer Pipes as Affecting their Long Term Behaviour

Author(s) : Janson

The investigation has indicated that deflected uPVC pipes are subjected to a physical aging process, which gives rise to a lower rate of decrease in the E-modulus than has previously been assumed. Based upon these findings the long term ring stiffness of PVC sewer pipes is determined. Concerning the bending strength...
