Renovation of a DN 150 Refinery Wastewater Main in Burnaby, BC
Publication: Pipelines 2024
ABSTRACT
In Burnaby, BC, there was a need to refurbish over 200 m of a DN 150 refinery wastewater main. Installing a new carbon steel pipe was not practical because of the expected high corrosion levels; HDPE or PVC materials were not considered suitable alternatives due to potential issues related to thermal expansion. Flexible Fabric Reinforced Pipe (FFRP) systems present significant advantages as they operate independently from the host pipe and can navigate multiple bends while accommodating high-pressure ratings. Simultaneously, they offer a high level of stability thanks to a reinforcement layer made of aramid. These attributes, combined with a small construction footprint and short rehabilitation times, made FFRP the ideal technology for this rehabilitation project. This paper will outline the technical characteristics of the FFRP and describe the installation process along with its associated requirements. The paper then concludes with a report on the rehabilitation of a refinery wastewater main.
