10、Anlagen-, Behlter- und Rohrleitungsbau (DVS AG A 3) of the Normenausschuss Schweitechnik NAS (Welding Standards Committee). It is intended to submit this document to CEN/TC 121 “Welding” as a proposal for a European Standard. Amendments This standard differs from DIN 2559-2:1984-02 as follows: a) Di
11、mensions and tolerances have been harmonized with DIN EN 10216-1:2004-07 and DIN EN 10216-2:2004-07. Previous editions DIN 2559-2: 1976-04, 1984-02 DIN 2559-2:2007-09 4 1 Scope This standard specifies matching dimensions for butt joints welded from one side, with joint preparation as in DIN EN ISO 9
12、692-1, for welds on seamless steel tubes having dimensions and tolerances as in DIN EN 10216-1:2004-07, 8.7, or DIN EN 10216-2:2004-07, 8.7. This document helps ensure proper matching of diameters and wall thicknesses without extensive corrections being necessary. This document may also be applied t
13、o other cylindrical hollow bodies, by analogy. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any

18、ness t of the tube. The following three equations shall be used to calculate dp: For outside diameter tubes use the following equation: dp= Dminimal 2 tpFor inside diameter tubes use the equations below: dp= 1,01 d or dp= 1,02 dminIt is assumed that larger wall thicknesses are selected for inside di
19、ameter tubes to allow for weakening (holes). Where a weakening factor has not been used in calculations, the matching diameter dpshall be selected on the basis of the calculated wall thickness.

20、 DIN EN ISO 9692-1, Ref. no. 1.6, matched The equations specified in this standard are such that when preparing the matching diameter dpof outside diameter tubes, the wall thickness does not fall below the wall thickness tpfor any tube. The minimum allowable wall thicknesses tpfrom manufacturing are
21、 given in Table 9. For tubes with inside diameters as in DIN EN 10216-2:2004-07, Table 8, the minimum allowable wall thickness is given by subtracting the tolerance from the wall thickness t. For tubes with outside diameters as in DIN EN 10216-2:2004-07, Table 9, the minimum allowable wall thickness
22、 is identical with the minimum wall thickness tmin, given the lower tolerance limit of 0 mm. For tubes with inside diameters as in DIN EN 10216-2:2004-07, Table 10, the minimum allowable wall thickness is identical with the minimum wall thickness tmin, given the lower tolerance limit of 0 mm. Tables
23、 2 to 5 give various equations for calculating the matching diameter dpdepending on the nominal dimension used in the relevant standards (either the nominal outside diameter, nominal inside diameter, or the minimum inside diameter), or whether it is the mean nominal wall thickness or nominal minimum
24、 wall thickness. The values for dpin Tables 6 to 8 are rounded off to the nearest half or whole millimetre. Values calculated for dpin accordance with Table 3 are to be rounded off in the same manner. DIN 2559-2:2007-09 6 4.2 Tolerances Table 1 gives tolerances for the matching diameter dp. Table 1
