    Perforated Metal Sheet - Solid sheet approach

    Hello everyone, Framework I am currently working, for the first time, with perforated metal sheets. I am using them to create tubes and also curved panels. To analyse my structure, I tried using FEM but I didn't succeed since my NX wasn't able to support the huge amount of holes (I have panels...

    Seal for supercritical C02

    That is great! Do you recall which polymer you have used for that high pressure/temperature application? I have also checked spring energized options and they might be an alternative solution, much probably at the expense of a higher price.

    Seal for supercritical C02

    Hello Tuckabag, Thank you your feedback. You are right, I have double checked and PTFE o-rings are not indicated for active coupling/decoupling due to their lack of elasticity. Elastomers cannot be used since this application uses CO2 at 100 bar. At the end of the process, before opening the...

    Seal for supercritical C02

    Hello everyone, I am currently working on the connection of two cylindrical vessels that requires a sealing in-between. The environment is filled with super-critical CO2 (environment at 100bar and 65C with a pressure differential between the sealing of 0.01 bar), meaning that rubbers aren't...
