Industrial valves. Shell design strength - Tabulation method for steel valve shells Ingestion-build-232773 pipes and ducts etc that1 Scope This European Standard specifies the tabulation method for determining the wall thickness of valve bodies, bonnets and covers with essentially circular cross section made in forged, cast or fabricated steel. For valve shells with oval, rectangular or non circular shapes, see 8. 6. The range of PN or Class designations for which thicknesses are tabulated is: PN 2,5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160, PN 250, PN 320, PN
