PE Jointing Techniques [PE]

 

Plastic Pipes Conference Association # 1985 York

Maine, Stafford

Since 1969, when polyethylene pipe systems were first used to distribute gas in the U.K., the vast majority of joints have been constructed using heated tool fusion techniques. The jointing processes involved require a high level of operator participation. The paper describes the development of fusion jointing techniques which are less dependent upon the "human factor" and more likely to result in a better operating efficiency in difficult working environments. The jointing methods have been evaluated experimentally and theoretically using heat transfer calculations.

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...

Funded by a UK government “Smart” Award, the authors have researched, and partially developed, a novel concept for temporarily reducing the external diameter of a PE pipe and then allowing recovery to full diameter as a close fit within a host main. The novelty lies in the four-lobed collapsed pipe geometry, which...

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...

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,...
