DIN 2605 Pari 1 € 3 Price group In keeping with current practice in standards published by the International Organization for Standardization (/SO), a comma has been used throughout as the decimal marker. Dimensions in mm 1 Field of application This standard specifies seamless and welded steel elbows and bends that are intended to be butt welded to pipes. Although the wall thicknesses specified correspond to those of the pipes, these fittings do not permit operation at the same internal pressure as the pipe welded on, ¡.e. they have a reduced pressure factor (cf. table 1 and clause 5). 2 Types and designation 45“ elbow 90° elbow 180' bend r is to be calculated as follows: type 2: r = 1 ,O *da type 3:r- 1,5.da type 5: r- 2,5-da type 1 O: r = 5,O. da type 20: r-lO,O-da Designation of a type 3 (3) seamless (S) 90° (90) elbow in accordance with this standard (l), where da is equal to 88,9 mm and s is equal to 2 . 3 mrn, made from material belonging to material group G as in DIN 2609 (G): Elbow DIN 2605- 1 - 90 - 3 -88,9 X 2,3 S - G Continued on page 2 to 6 ~.
