METHOD OF LAYING LINED PIPELINE

摘要

A method of laying lined pipeline which actively and successfully removes air pockets which might be trapped in the annulus between the liner and the host pipe by progressively flooding the lined pipeline. Furthermore, the liner is brought into closer contact and engagement with the host pipe. The removal of air in the annulus enables the pipeline test pressure to stabilise more quickly and avoids the risk of potential collapse during operational service life in the event the pipeline pressures fluctuate or a vacuum is created during an emergency shutdown.
