13、repared by the Normenausschuss Rohrleitungen und Dampfkesselanlagen (Pipe-lines and Boilers Standards Committee).Supersedes December 1993 edition.Page 2DIN 2848 : 2002-06AmendmentsThis standard differs from the December 1993 edition as follows:a) The scope of the standard has been extended to includ
14、e pressure ratings PN 25 and PN 40.b) For PN 10 instrument nozzles, the d4value for a size DN1 of 25 was corrected and branch sizes (DN2) 40 and 50 have been dropped.c) Designations for steel and cast iron have been updated.d) Some new steel grades have been introduced.e) The specications have been
15、harmonized with DIN EN 1092-1.f) The standard has been editorially revised.Previous editionsDIN 2848: 1976-07, 1993-12; DIN 2848-10: 1982-01; DIN 2848-11: 1982- 01; DIN 2848-12: 1982-01.All dimensions are in millimetres.1 ScopeThis standard species dimensions and technical delivery conditions for an
16、ged steel pipes and anged steel or cast iron ttings, with lining, which are intended to be used at pressures of 10 bar (PN 10), 25 bar (PN 25) or 40 bar (PN 40). The components specied in this standard may also be used without lining. The lengths specied include the lining thickness, a (see gure 8).
