Computerised simulation of composite pipe connections for hydrogen service

虽然Smartflow在管端连接的小众行业拥有丰富的专业知识，并且可以通过物理管道测试来支持，但一些客户确实要求更科学的答案。当使用不同的材料将这些金属连接成聚合物管道时，这些“原始”金属的特性会发生变化。这可能包括机械和耐腐蚀性能。综合科学分析和物理材料测试项目将帮助我们吸引巨大的机会，因为氢气和CCUS（碳捕获，利用和储存）管道需求增长复合管道行业。Smartflow的端部连接包含一个锋利的锯齿形钢管件，该管件插入到复合管柱中，然后通过“挤压”的方式与聚合物尾管“咬合”，形成永久连接。我们知道这个系统是有效的，因为我们已经做过很多次了，但对于Smartflow来说，主动瞄准这些公司，而不是通过推荐，拥有一个独立的、“可共享”的、与特定客户无关的技术支持文件将会受益匪浅。Smartflow相信，通过与像Astute这样的研究机构进行一些独立的分析工作，这将使我们能够分享客户想要的关键数据。每个管道制造商的组成略有不同，但将我们的锯齿形管件“锻造”成复合管道的理论建模，然后进行计算测试，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一个定制的系统，但在用物理爆破测试验证结果之前，我们可以将这种建模方法作为第一步。

Although Smartflow have extensive expertse in the niche industry of pipe end connections and can back it up with physical pipe testing, some clients do request more scientific answers. As different materials are used to form these metal connections into polymer pipes, the characteristics of these 'raw' metals can change. This could include mechanical and corrosion resistant properties. A combined scientific analysis and physical material testing project will help us attract large opportunities as Hydrogen and CCUS (Carbon Capture, Utilisation and Storage) pipeline demand grows the composite pipeline industry. Smartflow 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. We know that this system works as we have done it a number of times, but for Smartflow to proactively target these companies rather than through referrals it would benefit hugely to have a technical supporting document that is independant and 'shareable' not associated with a specific client.Smartflow believe that by undertaking some analysis work independently with a Research Institute like Astute, this will allow us to share the critical data that our clients would want. Each pipe manufacturer has a slightly different composition, but the theory of modelling our serrated fittings 'swaged' into a composite pipe and then testing computationally would give confidence in our design capabilities. Whilst we would always need to design a system bespoke to our clients, we could use this modelling approach as a first step, before verifying the results with physical burst testing.
