Introduction: Structural Mechanics of External Pressure
While atmospheric storage tanks primarily resist internal liquid hydrostatic head, Vacuum Receivers and Moisture Separators (Knockout Pots) must resist external atmospheric pressure pushing inward. Without specialized vacuum engineering, FRP vessels can suffer sudden elastic buckling and catastrophic inward collapse.
1. Vacuum Stiffener Rings & Torispherical Heads
To resist negative pressures down to -760 mmHg, FRP vacuum receivers incorporate external circumferential stiffening ribs bonded directly to the structural shell, preventing ovality deformation.
2. Liquid Demisting & Separation
Internal impingement baffles separate liquid droplets from vacuum lines, protecting dry vacuum pumps from liquid ingestion and corrosion.
