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 : 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 : Cable Drawing Trough Deformed Plastic Ducts
Author(s) : Fairfield, Reid, Hounsome, Edwards, Sibbald
This paper provides estimates of the draw force needed to pull sub-ducts or cables through
a series of typical ducted utility networks. Variables such as : coefficient of friction between
the outside of the cable and inside of the duct, the main duct’s vertical diameter, the cable
bundle or sub-duct’s external...
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 : Examining the Performance of Semi-Structural Pipe Liners
Author(s) : Crunkhorn, Smith, Whiter, Mulheron
Cast iron pipes have been loaded to failure using a four point bending geometry under
displacement-controlled loading. Specimens were tested with various liner configurations :
unlined, epoxy resin lined or lined with one of two interactive (semi-structural) liners. Some
of the pipes also had a circumferential notch...
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...
1998 Gothenburg : Updating Retained Gastket Jointing Technology for PVC Pipes
Author(s) : Smith, Guzowski
Some forty years ago simple 0 ring joints for PVCu pipes were just being introduced as an alternative to solvent cemented joints. Rubber lip seal type of joints soon followed for both pressure and non pressure applications. Whilst in theory these designs were fine, both styles of joint had operational problems,...
1970 Southampton : Some Case Histories on the Use of Plastics Pipes
Author(s) : Ellis
in opening the paper I think I should first explain that I propose :ca deviate a little from the precise subject described in the title. When the !itle wzs agreea with the Organising Secretary, ! was under the impression that my company organisation was a good deal better than it now appears to be and, to my cost, !...
