Discussion



  • We need to decide on pneumatic valves

    • Requirements

      • Rated to 2000psi ~ FOS - 3.3 ish

        • Should we size it at 1000psi

        • what do we see at nitrogen decomp?

        • Look at cryolocking

        • we can have our burst disk rated as our valve with the assumption that the valve survives the pressure

        • look into failure modes

        • actuators and valves can be switched out

        • limit switches - magnetic vs non, thomas justify please

        • 20% to 50% price difference

        • determine needs vs wants

        • ask ryan what was the justification on burst disk sizing

  • Where do we pick out fittings

    • mcmaster

    • we need to make sure that the specs are provided

    • find other sites for fittings

  • manifold

    • find online or make - decide on
