Development of Multi-layer and Multi-material Composite Linepipe for Oil and Gas Applications

Shawcor Ltd.寻求扩大其目前的增强热塑性塑料管（RTP）产品线，以加强其在当今竞争激烈的全球市场中的地位。快速且具有成本效益的安装，耐腐蚀性和长期运行中承受高压的能力是RTPs的一些突出特性，这些特性越来越多地被用作石油和天然气作业中钢管的替代品。Shawcor致力于将其RTP产品的容量扩展到更高的服务等级，即温度和压力。在过去的两年中，在艾伯塔省-安大略省联合创新计划和NSERC CRD赠款的范围内，一个由阿尔伯塔大学和多伦多大学的研究人员以及Shawcor的专家组成的团队在探索新的具有成本效益的RTP解决方案方面取得了实质性进展。作为这项研究的一部分，开发了用于评估长期性能的建模和测试技术。合作研究工作已经确定了具有成本效益的复合管设计。已经探索了将耐腐蚀金属夹层添加到复合结构中以提供防止挥发物通过管壁扩散的屏障。通过本文提出的项目，将实现多层和多材料RTP的优化结构设计，包括机械性能的表征、失效机制的识别以及将试样中的性能与全尺寸操作相关联。其次，该项目旨在开发新的解决方案，以有效地结合RTP中的有机和无机材料层。该研究将包括短期和长期特性的实验表征。这些研究目标将推进成功开发新型多层和多材料RTP解决方案的关键知识。大学研究人员与工业合作伙伴合作，组成了一个专家团队，进行工程分析和设计。该项目将培养各种高素质人才，以获得与科学研究有关的技能，同时与工业高度相关。最终，这项研究将推动Shawcor在行业中的技术领先地位。

Shawcor Ltd. seeks to expand their current product line of reinforced thermoplastic pipes (RTPs) to strengthen their position in today's competitive global market. Quick and cost-effective installation, corrosion resistance and the ability to withstand high pressure in long-term operation are few outstanding characteristics of RTPs, which are increasingly being used as an alternative to steel pipe in oil and gas operations. Shawcor is committed to expanding the capacity of their RTP products to higher service ratings, namely temperature and pressure. Over the past two years, within the scope of joint Alberta-Ontario Innovation Program and NSERC CRD grants, a team composed of researchers from the University of Alberta and University of Toronto and experts at Shawcor has made substantial progress in exploring novel cost-effective RTP solutions. As part of this research, modeling and testing techniques for the assessment of long-term performance were developed. The collaborative research efforts have identified cost-effective composite pipe designs. The addition of corrosion-resistant metallic interlayers into the composite structure has been explored to provide a barrier against diffusion of volatiles through the pipe wall. Through the project that is proposed herein, optimized structural designs for multi-layer and multi-material RTPs shall be enabled, which includes the characterization of mechanical properties, identification of failure mechanisms and correlating properties in coupon specimens to the full-scale operation. Second, the project aims at developing novel solutions to effectively bond organic and inorganic material layers in RTPs. The study will include experimental characterization of short- and long-term properties. These research objectives will advance the knowledge that is critical to successfully develop novel multi-layer and multi-material RTP solutions. The university researchers in collaboration with the industrial partner form an expert team for engineering analysis and design. The project will train various Highly Qualified Personnel to acquire skills related to scientific research while being of high relevance to industry. Ultimately, the research will advance Shawcor's technology leadership in the industry.
