This European Standard is applicable to the selection of bolting for PN designated flanges in accordance with EN 1092 series and class designated flanges in accordance with EN 1759 series.
It specifies standards for dimensions, materials and technical conditions of delivery for bolts, stud bolts and nuts.
The bolting of within standard is selected for the combined use with flanges from the EN 1092 series and EN 1759 series but not for general purpose.
The selection of the materials is based on commonly used materials. It covers all pressure and temperature ranges of the general service of standard flanges.
For special applications other materials may be selected by the user.
In some cases, similar alloys have been included, which differ only by carbon contents (e.g. 0,25 % or 0,42 %), because of the different requirements of the national standards. When the new European Standards are produced, it is expected that the opportunity to rationalize these many grades will result in a reduction of standardized grades.
note:1) prEN 1759-1 is in preparation whereas prEN 1759-3 and prEN 1759-4 are publicly available.
