Combining CFRP Lining Systems with Other Pipeline Rehabilitation Technologies
Publication: Pipelines 2012: Innovations in Design, Construction, Operations, and Maintenance, Doing More with Less
Abstract
As pipelines nationwide continue to age, pipeline owners have increasingly looked at options for combining different rehabilitation technologies together to arrive at cost effective and durable solutions for infrastructure renewal. While carbon fiber reinforced polymer composite (CFRP) liners for internal structural strengthening of pipelines 30 inches and larger have been used with increasing frequency over the past 15 years, the combination of this precision trenchless technology with other pipeline rehabilitation methods which are more suited for continuous straight runs of pipeline is a more recent trend. Several projects completed or in the design phase within the past year have addressed combiningCFRP linings with other rehabilitation technologies including slip lining and cured-in place pipe, or CIPP. The combination of these rehabilitation methods helped to address some of the limitations of slip lining and CIPP such as addressing sharp bends and laterals. For certain applications, using multiple pipeline rehabilitation technologies in tandem provide pipeline owners cost effective solutions for long term repair and rehabilitation. The use of CFRP lining allows owners the opportunity to employ slip lining and CIPP in more applications such as pipelines with sharp bends and pipelines with multiple laterals or service connections. Information will be provided about the specific nature of designing systems CIPP and CFRP lining systems individually and jointly including connection detailing and where and how to best utilize both.
