Discussions - Sessions 1-6

Author(s) : Holmes-Walker 1974 Southampton

Mr. J. Kuik (Ethylene Plastique): Would polypropylene co-polymer pipes have a longer service life compared to the homo-polymers? If so could this explain the fact that British pipes seem to be made from co-polymers? Dr. W.F. Mueller: The difference between them is the impact resistance and this is also fixed in...

Flexible water pipes for high voltage cable cooling systems: A review of present practice and possible future developments

Author(s) : Beale 1974 Southampton

For a given system voltage, the power transfer capability of an underground cable circuit is determined by the amount of current which may be passed through the conductor. Although secondary heating effects occur due to dielectric and sheath losses, proximity effects, etc., the primary limitation is that due to the...

International developments in PVC gravity sewer design

Author(s) : Carter 1974 Southampton

I was privileged to present papers on the structural design of PVC sewers at the earlier Symposiums and again to report progress. UK entry into the Common Market makes it desirable to consider further PVC sewer laying practice and the results of experience in Continental European countries. Experience has been...

International standardisation - a pipe dream

Author(s) : Littlewood 1974 Southampton

Maybe Henry Ford had the right idea when he said of his cars, ‘You can have any colour you like as long as it is black! He would most certainly get a shock if he were to return to earth again and see the wide variety of ‘blacks’ now available. Perhaps his idea of standardisation represented the ideal situation...

Investigations concerning uPVC drain and sewer pipes and fittings

Author(s) : Vaelimaa 1974 Southampton

The experiences of utilizing uPVC pipes as. pressure pipes for fresh water have been both extensive and favourabie, In recent years uPVC has also been introduced as material for relatively thinwalled’ drain and sewer pipes buried in the ground. In connection with this development a lot of research work has been...

Plastics pipe in land drainage and irrigation

Author(s) : Ede 1974 Southampton

In considering the role for plastics il should be emphasised that as a consultant the issue as between choice of a traditional material or product and its plastic counterpart in general follows a logical sequence of selection in which in the end the most suitable material emerges either on technical or economic...

The Analysis of practical failures of plastic pipelines

Author(s) : Marshall, Williams 1974 Southampton

The role for plastics in developing countries

Author(s) : Stern 1974 Southampton

Author(s) : Barton, Cliffe 1974 Southampton

The 400 kV cables installed by the Central Electricity Generating Board to match their largest 400 kV overhead lines appear to set the limits of conductor size which cable manufacturers produce, Before the Severn installation, with which this Paper in the main deals, the maximum size of conductor available for 400 kV...

Unusual hospital effluents and plastics drainage

Author(s) : Payne 1974 Southampton
