不好意思我记错了 ASME是规定可以用bars和rods 所以除了法兰盖不能用板加工,以下是ASME B16.5的规定
5 MATERIALS
5.1 General
(a) Materials required for flanges and flanged fittings
are listed in Table 1A with the restriction that plate
materials shall be used only for blind flanges and reducing
flanges without hubs. Flanges and flanged fittings
shall be manufactured as one piece in accordance with
the applicable material specification. Assembly of multiple
pieces into the finished product by welding or other
means is not permitted by this Standard.
(b) Recommended bolting materials are listed in
Table 1B (see para. 5.3).
(c) Corresponding materials listed in Section II of the
ASME Boiler and Pressure Vessel Code may be used
provided that the requirements of the ASME specification
are identical to or more stringent than the ASTM
specification for the Grade, Class, or type of material. |
