In order to increase market share in a competitive global environment, Flexpipe Systems, a division of ShawCor Ltd., recently launched a new product called FlexFlow Linepipe, which is a larger diameter fiber-reinforced thermoplastic composite linepipe that will be made available in 6" and 8" inside diameters, with 750 psi and 1500 psi pressure ratings. Flexpipe's product line is currently limited to pipe solutions with diameters of less than 4". An engineering team consisting of Shawcor experts in Ontario and Alberta has made substantial progress in the development of the new product, and prototype development and production of large diameter composite linepipe is well underway. Pipe segments will be limited in length since, due to the larger diameter, the new product cannot be spooled and transported like as Flexpipe's small-diameter legacy products. This in turn requires a pipe assembly using suitable reinforced connector fittings. For the 750 psi rated linepipe, reinforced electrofusion fittings have been developed for the reliable joining of pipe segments. However, fittings capable of more efficiently sustaining the loadings that occur in the high-pressure 8" linepipe are required. In this case, the stress distribution in the pipe joint caused by sustained axial loading and 60°C must be managed to remain for 20 years or more within material limits including a safety margin. Developing a suitable fitting for the given material system is a considerable technological challenge, and Shawcor/Flexpipe is seeking the expertise from the Ontario and Alberta university researchers to address these challenges and develop a fundamental understanding for a novel pipe joint design that meets performance requirements and is reliable, cost-effective, long-lasting even in adverse environmental conditions. The goal of the project is to establish an advanced knowledgebase and develop a novel solution for a high-pressure fitting/coupling for the linepipe that provides required strength and a high degree of durability and safety. The development of a novel pipe joint offers the opportunity to integrate sensing functionalities and functionally graded material systems for exceptional reliability, which would further advance Shawcor's technology leadership in the industry.

为了在竞争激烈的全球环境中提高市场份额，Shawcor Ltd.部门Flexpipe Systems最近推出了一种名为Flexflow LinePipe的新产品，该产品是一个较大的直径纤维增强的热塑性复合材料管道管道，该产品将在6“和8”的内部直径内提供，具有750 PSI和1500 PSI和1500 PSI压力率。 Flexpipe的产品线目前仅限于管道解决方案，直径少于4英寸。由shawcor专家组成的工程团队在安大略省和艾伯塔省和艾伯塔省的新产品的开发中取得了长足的进步，而原型的开发和原型的开发和生产大型直径复合线索的运输良好，因为较大的产品和新产品的速度是较大的产品，因此，新产品的运输范围是较大的产品，该产品的长度是较大的，即较大的产品，该产品较大，直径较大，直径较大，直径范围是较大的直径范围。小直径的旧产品依次使用合适的加固连接器配件，用于750 PSI额定的线条，增强了电渗置配件，以使管段的可靠连接到可靠的配件。在这种情况下，必须在包括安全边缘在内的物质极限内保留20年或更长时间，由持续的轴向负荷和60°C引起的管子关节的应力分布。为给定材料系统开发合适的配件是一个巨大的技术挑战，肖科尔/弹性人正在寻求安大略省和艾伯塔省大学研究人员的专家，以应对这些挑战，并对满足性能的新型管道设计和可靠，成本效益，持久，甚至在不利的环境条件下，对新颖的管道关节设计有了基本的了解。该项目的目的是建立一个先进的知识库，并为线条管的高压拟合/耦合开发新颖的解决方案，该线管提供所需的强度以及高度的耐用性和安全性。新颖的管道关节的开发为将传感功能和功能分级的材料系统集成为特殊可靠性提供了机会，这将进一步提高Shawcor在行业中的技术领导。
