9、4 1 Scope This standard applies to weld neck flanges for pressure vessels. General requirements for flanges are specified in DIN 28030-1. Tolerances (limit deviations) for flanges are specified in DIN 28030-2. DIN 28031 covers weld flanges for unpressurized vessels. DIN 28033 covers weld flanges for

10、 pressure vessels. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

These allowances include: the heigh

18、t of the raised face for type B1 facings; the height of the tongue for type C facings; the height of the spigot for type E facings; the depth of the recess for type F facings; where appropriate, an allowance for spot facing. Machining allowances shall be selected so that the facing profile can be ma

19、nufactured without difficulty even where there is the expected warping due to the welding process. Other machining allowances shall be agreed between the buyer and the flange manufacturer.
