Manufacturing Defects in Thermoplastic Composite Pipes and Their Effect on the in-situ Performance of Thermoplastic Composite Pipes in Oil and Gas Applications

Abstract Thermoplastic composite pipes (TCP) are a form of fibre reinforced thermoplastic that have proven benefits such as being lightweight and non-corrosive. However, during manufacturing, certain defects induced because parameters which eventually affect TCP performance in-service. Current manufacturing techniques challenged with on-the-spot detection the pipe is regularly monitored. When defect noticed, process stops, action taken. stopping costly; hence it vital to decrease downtime manufacturing. Potential solutions through optimisation for reduction an in-depth understanding effect cause formation in pipe. This article provides overview influence on end performance. intimately linked material features, properties, The features determinants technique be used. For TCP, melt fusion bonding involving heating consolidation among other factors speed pull force. Thermal behaviour essential at this phase determines curing rate study indicates laser better heat source efficiency terms.
