Hi All,

Working on a High Pressure Steam system and our team is considering using a stopple on a line to prevent a shut down. See this video: https://www.youtube.com/watch?v=VWhmva4pQlQ

First question: has anyone had any experience with these in steam systems?

Second question: the operation leaves a split weld tee permanently in place, how would one go about modeling this? Higher SIF? Higher Stiffness? Thoughts?

Thanks!

Louie
