Swagelining - A Pipeline Renovation Technique [PE]


Plastic Pipes Conference Association # 1992 Eindhoven

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, known as Swagelining, which produces a close fit inside the existing main, thus maximising flow Capacity.

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...
