For the UK polyethylene (PE) gas pipe network, the first installations now exceed 40 years in the ground, with an original design life of 50 years. It was thus timely to review the current condition and performance history of these first generation PE materials. A major 4 year project was started in 2010 to examine...
2001 Munich : The Challenge and Opportunity of High Voltage Cable PipesAuthor(s) : Stafford, Bircumshaw
The very high costs of underground electrical power transmission preclude its widespread
usage even where social and environmental concerns make it highly desirable. This paper
examines the technologies of below ground alternatives to overhead power lines and
identifies the opportunities for introducing pipeline...

1995 Edinburgh : New Opportunities for New PipesAuthor(s) : Stafford
This paper is conceived as a review of current trends in the market and in the technology for thermoplastic pressure pipes. The application of any technical development depends on that subtle combination of the pull of needs and the push of new ideas. For more than 25 years British Gas has been actively involved in...
1995 Edinburgh : Plastic Lined Pipelines for Corrosion ControlAuthor(s) : Maine, Hicke
Due to space limitations on offshore platforms the treatment of well head fluids is expensive. To reduce the costs there is a move towards unmanned offshore platforms, or subsea completions. The result of such moves is that the pipelines are required to carry all produced fluids, including wet acid gases, in the...
1992 Eindhoven : Swagelining - A Pipeline Renovation TechniqueAuthor(s) : Maine, Ross
Renovation of an old main, by insertion of a medium density polyethylene (MDPE) pipe, reduces costs in excavation and reinstatement. Traditionally the inserted pipe is smaller than the existing main resulting in a reduction in flow capacity. This paper reviews the development and evaluation of a lining technique,...
