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.

随着地下储气库对氢气和二氧化碳分布的需求不断增加，复合管道中末端连接的挑战正成为制造商关注的关键问题。Smartflow在这个利基行业拥有广泛的设计和制造专业知识，并有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形成聚合物管道的金属连接，这些“原始”金属的特性可以改变，包括它们的机械和耐腐蚀性能。结合科学的有限元分析和物理材料测试项目，既可以支持Smartflow的新技术设计，也可以为复合管道行业对氢气和CCUS管道的需求增长带来巨大机遇。Smartflow的末端连接包括一个锋利的锯齿形钢管件，该管件插入复合管中，然后“挤压”出来，“咬合”到聚合物衬管中，从而形成永久连接。虽然Smartflow已经成功实施了该系统多次，但在与管道制造商主动实施解决方案时，它具有独立且可共享的技术分析。此外，新的氢准备连接设计的FEA建模将加速整个开发计划。与Astute一起进行独立分析工作，使Smartflow能够共享客户所需的关键、独立数据。由于每个管道制造商的管道组成略有不同，因此将我们的锯齿形管件“锻造”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定制系统，但我们可以将这种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。
