2014 Chicago : Determining the Processing Quality of PVC Pipe by DSC – How Precise?
Author(s) : DALE B. EDWARDS, ANAND R. SHAH, DONALD E. DUVALL
Differential scanning calorimetry (DSC) has been used to study the processing of PVC pipes. This work has been largely embodied in ISO 18373-1-2007, Rigid PVC Pipes –differential scanning calorimetry (DSC) method – Part 1: Measurement of the processing temperature and Part 2: Measurement of the enthalpy of fusion for...
2004 Milan : Erosion Performance of Plastics Pipes
Author(s) : Fairfield, Campbell, Reid
This work examines the wear properties and erosion resistance of plastic pipes under dynamic
fluid impact and cavitation conditions. Testing to evaluate the performance of a range of
plastics was undertaken. A test rig was calibrated for : flow stability, pressure hysteresis,
frictional head loss, time to target...
2004 Milan : Manufactured Aggregate as Imported Backfill Material for Plastics Pipes
Author(s) : Newport, Wijeyesekara, Edwards
Research work undertaken at the University of East London has produced new forms of sustainable manufactured aggregate, which gives a backfill material which has many advantages over natural materials. The unique geotechnical properties of the aggregate make it an idea material for the laying of plastic pipes allowing...
2001 Munich : Complex Yield Behaviour of PE100 Resin on Plane Strain Tensile Specimen
Author(s) : Choi, Lee, Broutman, Edwards, Palermo, Cho, Choi, Park
In recently designated plane strain grooved tensile (PSGT) methodology of ASTM F2018
standard, a groove in the direction perpendicular to the loading axis allows biaxial stress
state to be generated under a uniaxial loading. The biaxial stress state produced very closely
approximates the internally pressurized pipes...
2001 Munich : Optimisation of Corrugated Duct Profiles
Author(s) : Fairfield, Hounsome, Reid
This paper presents a method of optimising the distribution of plastic in a twin-walled,
corrugated duct. This could be used to achieve maximum stiffness for minimum linear
mass or a desired target stiffness for any envisaged market for the product. Spreadsheet
optimisation routines1 based on a generalised reduced...
2001 Munich : Risk Analysis and Plastic Duct Design
Author(s) : Drummond, Fairfield, Wamuziri
First Order Second Moment (FOSM) analysis techniques, employed in the development of
limit state design codes, allow designers to account for the variations and random nature of
the material properties and load effects inherent in the design of engineered structures. A
generated non-linear equation is used in...
1998 Gothenburg : Plastics Pipes - Future in the Water Industry
Author(s) : Stokes, Edwards
The paper examines the business and regulatory background to the
infrastructure investments anticipated in the next few years, from
the point of view of a major UK Water Company. Past performance
of the use of plastic pipes for sewers and water mains are examined.
Shortcomings of the products are identified and...
1982 York : Extrudate Cooling of Medium Density Polyethylene Pipe Sections
Author(s) : Edwards,Ellis, Georghiades,Smith
A model is presented for the prediction of cooling rates and temperature profiles during the cooling and solidification of M.D.P.E. pipes. Experimental measurements from an industrial production line are reported and these confirm the predictions of the model. Finally, the model is used to determine the most important...
