FEA Simulation and Verification of Composite Pipeline End Fittings for Hydrogen and CCUS service

随着地下储存氢气和二氧化碳的需求不断增长，与复合管道中的端部连接相关的挑战正成为制造商的关键问题。Smartflow在这个利基行业拥有广泛的设计和制造专业知识，并得到物理管道测试能力的支持。然而，客户通常需要更科学的分析，因为不同的材料用于将金属连接到聚合物管道中，并且这些“原始”金属的特性可能会发生变化，包括它们的机械性能和腐蚀性能科学的有限元分析和物理材料测试相结合的项目将支持Smartflow的新技术设计，并随着氢气和CCUS管道需求的增长，复合管道行业Smartflow的端部连接包含一个尖锐的锯齿状钢接头，该接头插入复合管中，然后“锻造”以“咬”入聚合物衬里，以产生永久连接。虽然Smartflow已多次成功实施该系统，但在与管道制造商积极实施解决方案时，拥有独立和可共享的技术分析。此外，新的氢就绪连接设计的FEA建模将加速整体开发计划。与Astute进行独立分析工作，使Smartflow能够共享我们客户所需的关键，独立的数据。由于每个管道制造商的管道组成略有不同，因此将我们的锯齿状管件“型锻”成复合管道，然后进行计算测试，这将使我们对设计能力充满信心。虽然我们总是需要为客户设计定制的系统，但我们可以使用这种FEA建模方法作为第一步，然后通过管道连接系统的物理爆破测试验证结果。

With the increasing demand for the distribution of Hydrogen and Carbon Dioxide for Underground Storage, the challenges associated with end connections in composite pipelines are becoming a critical concern for manufacturers. Smartflow has extensive design & manufacturing expertise in this niche industry, supported by physical pipe testing capabilities. However, clients often require more scientific analysis as different materials are used to form metal connections into polymer pipes, and the characteristics of these 'raw' metals can change, including their mechanical and corrosion-resistant properties.A combined scientific FEA analysis and physical material testing project would both support Smartflow's new technical designs and also unlock large opportunities as Hydrogen and CCUS pipeline demand grows in the composite pipeline industry. Smartflow's end connections incorporate a sharp serrated steel fitting that is inserted into the composite pipe and then 'swaged' out to 'bite' into the polymer liner to produce a permanent connection. While Smartflow has successfully implemented this system multiple times, having an independent and shareable technical analysis when proactively implementing solutions with pipeline manufactures. Additionally, the FEA modelling of new Hydrogen ready connection designs the will accelerate the overall development programme.Undertaking independent analysis work with Astute, allows Smartflow to share the critical, independent, data that our clients require. As each pipe manufacturer has a slightly different pipe composition, modelling our serrated fittings 'swaged' into a composite pipe and then testing computationally would give confidence in our design capabilities. Although we would always need to design a system bespoke to our clients, we could use this FEA modelling approach as a first step before verifying the results with physical burst testing of the pipe connection system.
