2014 Chicago : Plough-in of Large Diameter Polyethylene Pipes
Author(s) : Alan Whittle, Jim Campbell
The coal seam gas industry in Australia is currently undergoing a major expansion with over 50,000 km or 30,000 mile of PE100 pipes to be installed in diameters ranging from DN110 to DN710. The pipes are being used to carry produced water, gas and treated water. The considerable quantity of pipe to be installed in...
2012 Barcelona : Performance and sustainability advantages of PVC sewer pipes in australia
Author(s) : Alan Whittle, Nigel Jones and Mark Heathcote
PVC has been used successfully for sewer and sanitary drainage pipes in Australia
for over 40 years. It is the predominant material for these applications. The reason
for this success is the superior, all round performance of PVC piping systems
compared to the various alternatives. Equally important has been the...
2004 Milan : Predicting the Residual Life of PVC Sewer Pipes
Author(s) : Whittle, Tennakoon
Ipswich Water commenced reviewing the service lives of different pipe materials in its
gravity sewer system. Unlike other pipe materials, PVC sewers did not have failure histories,
or deterioration revealed in CCTV inspections, even after 25 years of service. Therefore
establishing a realistic predicted life was not...
2004 Milan : Resistance of PVC-U and PVC-M to Cyclic Fatigue
Author(s) : Whittle, Teo
PVC-U and PVC-M pipes may be used in applications where they are subjected to cyclic
pressures generated by the operation of pumps and valves. It is therefore important that the
pipe material’s response to cyclic loading is quantified and that pipelines are designed and
operated within the material’s established...
2001 Munich : A Study of the Solvent Cement Bond for PVC and ABS Pipe Joints
Author(s) : Tjandraatmadia, Burn
To increase understanding of chemical jointing in pipes, the strength of solvent cement
joints in acrylonitrile-butadiene-styrene (ABS) and poly(vinyl chloride) (PVC) pipes was
investigated, using mechanical tests and morphology studies. The strength of solvent cement
increases with curing time, and it was found that...
2001 Munich : Assessment of the Strength and Toughness of Modified PVC Pipes
Author(s) : Whittle,Burford, Hoffmann
A series of modified PVC pipes, with different concentrations of chlorinated polyethylene,
were manufactured under carefully controlled processing conditions. The strength and
toughness of each pipe was measured by a variety of methods including uniaxial tensile
strength, notched C-ring, essential work of fracture,...
2001 Munich : The Role of Planning Models in Pipeline Rehabilitation
Author(s) : Burn, Davis, DeSilva, Marksjo, Tucker, Geehman
To allow long-term strategies to be implemented for the replacement or refurbishment of
water pipelines, a planning model called the Pipeline Asset and Risk Management System
(PARMS) has been developed. This model, although based upon life cycle costing
methodologies has been designed to incorporate whole of life...
1998 Gothenburg : Impact Test for Preventing RCP
Author(s) : Brown, Lu
The S4 critical temperature (CT) for 110 mm pipe was correlated with the plane stress
impact energy for 13 resins. A plane stress impact (PSI) test is offered as an inexpensive
way to control RCP by determining the lot to lot variations of the critical temperature of a
resin. Details of the PSI test are presented.
1998 Gothenburg : Long-Term Creep of ABS Pipes at Variable Temperatures
Author(s) : Lu, Burn
One of the characteristic behaviours of plastics (or viscoelastics) materials is the creep
phenomenon, which is defined as the continuing deformation under a constant load with time.
Although research on creep of plastics pipes has been widely carried out in other plastics, little
work has been reported for creep in...
1988 Bath : The Failure of Polyethylene Gas Pipe Materials by Slow Crack Growth
Author(s) : Brown, Lu
Two of the pipe resins that are commonly used in
the USA are compared with respect to their relative life times. The improvement in the performances of the currently used materials compared to
the older material from the same producer have
been measured. T h e 1ahoratoi-Y conditions for
producing brittle failure in...
