Sustainable multi-material polymers for new generation of low carbon footprint pipelines

钢管传统上用于在高温和极压下输送流体。然而，腐蚀问题和相关的管道故障已经促使了对增强聚合物管道的驱动。与钢管相比，增强热塑性塑料管（RTP）具有多种优势，包括灵活性和可回收性，因此碳足迹低，由于较低的比重和可缠绕性而易于运输，耐用性增加，安装和运营成本降低。在这种情况下，主要目标是开发一种新型的多材料结构化或混合的衬里，其实现目标温度和压力等级所需的性能，同时与构造为单层工程热塑性塑料的衬里相比成本更低。为此，多材料结构化或共混的衬里将旨在利用商品热塑性聚合物的可回收性、低成本以及更多添加的高性能热塑性塑料的优点，以获得其结构完整性和改善的流体渗透阻力。 技术成果将是开发这种下一代管线管产品，并将保留在加拿大，这代表了增值知识，可以在全球行业潜在的新型低碳足迹管道技术的商业化或许可方面做出未来的战略决策。加拿大的经济利益将是增值知识，技术保留和制造业的市场领导地位，特别是重点放在关键的能源部门。预计此次合作完成的研发贡献将导致引入新型低碳足迹Linepipe技术，该技术也可用于未来各种管道系统的开发。此外，在地球仪的管道建设项目中采用这种技术，可能会使设在哥伦比亚的公司在制造和运输领域获得新的收入来源。项目成果的社会影响也可能对加拿大该行业的整体福祉产生重大影响。新型低碳足迹管道解决方案的制造将为该行业提供增长机会。可能会雇用更多的劳动力，以协助实施和进一步发展本项目。此外，管道运营商对技术和成本最先进的产品的积极反应将增加对产品供应的需求，这将进一步创造就业机会，以满足不断增长的生产需求。更重要的是，设想的管道复合材料设计将有助于保护环境。这将通过限制管道中金属部件的使用来实现，从而减少这些产品的制造对环境的影响，并消除管道的长期腐蚀。内衬的拟定多材料设计将用于限制并可能防止流体渗透，这将减少总体温室气体排放，延长使用寿命，并通过保护产品的结构完整性来降低管道的故障率。

Steel pipes have traditionally been used for the transportation of fluids at high-temperatures and extreme pressures. However, corrosion problems and associated pipe failures have motivated a drive to reinforced polymeric pipe. Compared to steel pipes, reinforced thermoplastic pipes (RTPs) offer several advantages including flexibility and recyclability hence low carbon footprint, ease of transportation due to lower specific mass and spoolability, increased durability, lower installation and operational cost. In this context the primary objective is to develop a new class of multi-material structured or blended liners which achieve the required performance for the targeted temperature and pressure ratings while being lower in cost compared to liners constructed as a single layer engineering thermoplastic. To this end, the multi-material structured or blended liners will aim to take advantage of the recyclability, low cost of commodity thermoplastic polymers in combination with more addition of high-performance thermoplastics for their structural integrity and improved fluid permeation resistance. The technical outcome will be developing this next generation linepipe product would be retained in Canada, which represents the value-added knowledge that would allow to make future strategic decisions in terms of the commercialization or licensing of potential novel low carbon footprint piping technologies for the industry around the world. The economic benefits to Canada will be the value-added knowledge, technology retention and market leadership in manufacturing with a special focus on the key energy sector. It is anticipated that the contributions from the R&D completed by this collaboration will result in the introduction of novel low carbon footprint Linepipe technology that can also be utilized for a variety of future piping system developments. Moreover, new revenue streams for Canadian-based companies in the manufacturing and transportation field may become possible with the implementation of such technology with piping construction projects around the globe. The social impact from the project outcome can also be substantial to the overall well-being of the industry in Canada. The manufacturing of novel low carbon footprint pipeline solutions will provide growth opportunities for the sector. The employment of additional workforce is likely to occur to assist with the implementation and further development following this project. Moreover, a positive response from piping operators to a product at the cutting edge of technology and cost would increase the demand for product offerings which would further induce job creation in order to satisfy the growing production needs. More importantly, the envisioned composite design of the pipeline would contribute to protecting the environment. This will be achieved by limiting the use of metallic components in the pipeline, thereby reducing the environmental impact of the manufacturing of these products and eliminating long term corrosion of the pipeline. The proposed multi-material design of the liner will serve to limit and possibly prevent the permeation of fluids which will reduce the overall greenhouse emission and extend the service life and lower the failure rate of the pipeline by protecting the structural integrity of the product.
