Industrial valves. Shell design strength. Tabulation method for steel valve shells
This European Standard specifies minimum requirements for the design, testing and production testing of valves, including appropriate fittings, which are connected to mobile or static LPG pressure vessels above 150 l water capacity. Pressure relief valves and their ancillary equipment, contents gauges and automotive LPG components are outside the scope of this European Standard. This European Standard does not apply to refineries or other process plants.

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 400, Class 150, Class 300,Class 600, Class 900, Class 1500, Class 2500, Class 4500. Pressure/temperature ratings are specified for each material group for the above PN Standard Class and Special Class designations. The non-destructive examination procedures and acceptance levels that need to be applied to the valve shell components in order for the valve to be used at Special Class pressure/temperature ratings are defined. Details are also given for the alternative rules for small bore valves of DN 65 and smaller designated as Limited Class. This standard does not apply to threaded end valves: - DN 80 or larger; - or which have pressure ratings greater than Class 2500; - or which operate at temperatures greater than 540 °C. Socket welding end valves DN 80 or larger are outside the scope of this standard.
Industrial valves - Shell design strength - Part 1: Tabulation method for steel valve shells
This European Standard specifies the calculation method for valve shells manufactured in metallic materials other than steel. The loadings to be accounted for are in accordance with EN 12516-2. Design methods are in accordance with EN 12516-2, design by formulae according to the relevant clauses.
Industrial valves - Shell design strength - Part 4: Calculation method for valve shells manufactured in metallic materials other than steel
This European Standard specifies the method for the strength calculation of the shell with respect to internal pressure of the valve.
