Unfired pressure vessels - Part 6: Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron
12-31-2009
07-22-2009
This European Standard specifies requirements for the design, materials, manufacturing and testing of pressurevessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidalgraphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements,bosses etc.The allowable grades do not include lamellar graphite cast iron grades for ferritic and austenitic grades, which areexplicitly excluded from this European Standard because of low elongation and brittle material behaviour, whichrequires the use of different safety factors and a different approach.NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and fortheir corrosion resistance properties.NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 3 and 4. Service conditions are given inClause 4.
