This European Standard has been prepared under a mandate given to GEN by the European Commission and the European Free Trade Association. This Europea

It covers all pressure and temperature ranges of the general service of standard flanges. For special applicat
20、ions 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 oppor
21、tunity to rationalise these many grades, will result in a reduction of standardised grades. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

Annex A (normative): Stud bolts threaded full length Stud bolts shall be threaded full length. The points shall be chamferred or rounded at the manufacturers option. The height of point sha
42、ll be a maximum one times the pitch of thread. The length of stud bolts has to be measured including points. The lengths are stepped by increments of 5 mm for length up to 80 mm, by increments of 1 O mm for length above 80 mm and up to 200 mm, and by increments of 20 mm for length above 200 mm. Thre
43、ad in accordance with IS0 261, IS0 965-2 tolerance class 6g. Type of thread is either coarse thread or above M39 fine thread with 4 mm pitch. The type of thread shall be selected by the user. Fine thread above M39 is normally used for industrial plants, coarse thread up to and including M64 is norma
44、lly used for water service. Page 7 EN 1515-1 : 1999 Annex B (informative): Equivalent bolting materials Bolting materials according to national standards which are comparible to the materials of European Standards is given in table B.1. These materials have similar chemical composition and similar s
45、trength level as the compared materials of European Standards. They can be used if agreed upon by the purchaser.
