Saipem最近开发了一种用于深水应用的创新管道修复系统。通过锻造工艺确保密封，该锻造工艺使管线管材料在非常高的应变水平下塑性变形。为了评估材料在锻造成系统时对高塑性变形的响应，已经执行了专门的测试程序，并结合FEM计算，以评估塑性应变过程期间和应变后加时效条件下的材料响应。
An innovative pipeline repair system for deepwater applications has been recently developed by Saipem. Sealing is ensured by a forging process which plastically deforms the linepipe material at very high strain level. In order to evaluate the material response to high plastic deformation when forged into the system, a devoted testing programme has been performed coupled with FEM calculations so to assess the material response during the plastic straining process and in the after straining plus ageing conditions.
