Annex A is informative. DIN 28030, Flange joints for process vessels consists
6、 of: Part 1: Technical delivery conditions Part 2: Limit deviations for flanges Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent rights. Amendments
7、 This standard differs from DIN 28030-1:2003-06 as follows: a) the TRB (German technical rules on pressure vessels) are no longer cited; b) tables with pressure and temperature ratings are no longer included; c) bolts: Bolts are to be selected in accordance with the DIN EN 1515 series of standards;
8、d) materials: Traceability and quality characteristics have been harmonized with DIN EN 1092-1 and the AD 2000 Merkbltter (German Pressure Vessel Code) (taking the requirements of the Pressure Equipment Directive 97/23/EC into consideration); e) the standard has been editorially revised.

The
10、se flanges are classified according to the nominal sizes of chemical equipment as in DIN 28105. This standard applies to flanged joints as in: a) DIN 28031 for unpressurized process vessels; b) DIN 28033 and DIN 28034 for pressurized process vessels. It does not apply to pipe connections or valve co
11、nnections. Pipe flanges according to DIN EN 1092-1 are usually only used for pipe connections and other similar types of connection (e.g. for nozzles and valves). Flanges for process vessels have smaller connecting dimensions than flanges for pipes etc. as in DIN EN 1092-1 and cannot be combined wit

18、everal components (e.g. flange, bolts, gasket). The flanged joint design is particularly dependent on the combination of components used and the means of joining them. On a case-by-case basis it will be necessary to re-calculate the flange design due to the significant influence of the sealing param
19、eters and the scatter of the bolt tightening method. The pressures listed in DIN 28033 and DIN 28034 are guidance values for the purposes of general orientation and pre-selection. 4 Flanges 4.1 Types, facings and design Types, facings and designs are specified in DIN 28031, DIN 28033 and DIN 28034.
20、4.2 Connecting dimensions The connecting dimensions for flanged joints are largely determined by the flange outside diameter, facing type, the number and size of bolts, and the bolt circle diameter. Dimensions specified in DIN 28031, DIN 28033 and DIN 28034 ensure uniform connecting dimensions and a
21、re based on the following considerations: a) the number of bolts is divisible by 4; b) the number of bolts is in a constant ratio to the vessel size (from size DN 400, the number of bolts = 0,04 nominal size); c) access to the bolts with a wrench is ensured; d) the bolt circle diameter is such that
22、the gasket is sufficiently wide; e) the tolerances on the diameters of dished heads as in DIN 28011 and DIN 28013 have been taken into consideration. 4.3 Materials Materials as in DIN EN 1092-1 may be used for flanges as in DIN 28031, DIN 28033 and DIN 28034. Other materials shall be agreed between
23、the buyer and the manufacturer. The flange manufacturer shall ensure traceability of the material. It shall not be possible to mistake the material for another material. 4.4 Manufacture and welding Flanges can either be seamless rolled, pressed or forged; bent from rolled sections and welded; cut as
24、 strips from sheet products and bent and welded; flanges for unpressurized vessels and plate flanges for pressurized vessels of nominal sizes up to and including DN 800 can be cut from the sheet in circular sections. Rolled sections may be forged or rolled sections. DIN 28030-1:2013-09 6 Where strip
25、s cut from sheet are used to manufacture the flange, the through-thickness direction of the sheet shall be perpendicular to the flange axis in the case of flanges as in DIN 28034. The welding process used shall be resistance welding and, in particular, flash butt welding. The welding and any necessa
26、ry heat treatment of flanges for pressurized vessels shall meet the requirements of Directive 97/23/EC (e.g. by complying with the AD-2000 Merkbltter, HP series) and the relevant material standards. Subsequent heat treatment can be necessary, for example when the forming process does not begin or en
27、d within the prescribed temperature range, or where the permissible degree of deformation is exceeded in the case of cold forming. 4.5 Finishing The required surface finish for each type of flange is specified in DIN 28031, DIN 28033 and DIN 28034. 4.6 Tolerances Tolerances (limit deviations) for th
28、e flanges in the ready-to-use condition are specified in DIN 28030-2. 5 Designation of facings Facings shall be designated as in Table 1.

The FB or FS gaskets that are suitable for flanged joints can be used for any nominal size, and are to be taken from DIN 28040 on the basis of the bolt thread si

Gasket types and materials shall be selected on the basis of their pressure, temperature and chemical resistance.
