Research Program 1 - Materials
More Efficient Use of Materials for Energy Pipelines
The overall aim of Research Program One was to lower the cost and extend the life of energy pipelines by using materials more efficiently and avoiding material-related problems that result in economic losses.
A focal point of the program was welds and welding techniques. A key goal of this focal point was to produce a user friendly industry tool for the prevention of weld metal hydrogen assisted cold cracking.
The program also supported research into the use of higher strength steels by providing information and expertise regarding methods of manufacture, specification and joining.
Finally, the program had projects assisting with the specification of line pipe steels and the determination of the mechanical properties of the steel.
The Steering Committee overseeing RP1 was chaired by John Piper and the Program Leader was Professor Madeleine du Toit (University of Wollongong).
