Re: [MW:10707] WPS Qualification / Pressure Vessel / ASME Sec VIII, Div 1

Hi,
As per QW420.2 ASTM material also can be considerd as Corresponding P-Numbers of ASME Materials.pls.find below the CODE extraction

QW-420.2 S-Numbers. S-Numbers are assigned to
materials that are acceptable for use by the ASME B31
Code for Pressure Piping, or by selected Boiler and Pressure
Vessel Code Cases, but which are not included within
ASME Boiler and Pressure Vessel Code Material Specifications
(Section II).
Material produced under an ASTM specification shall
be considered to have the same S-Number or S-Number
plus Group Number as that of the P-Number or P-Number
plus Group Number assigned to the same grade or type
material in the corresponding ASME specification (i.e.,
SA-240 Type 304 is assigned P-No. 8, Group No. 1; therefore,
A 240 Type 304 is considered S-No. 8, Group No. 1).

Thanks & Regards,

Dear All,
 
Design Code: ASME Sec VIII, Div 1
U-Stamp Pressure Vessel
 
Reference Code : ASME Sec IX, Edition 2007, Add 09
Material of Construction: SA 516 Gr 70N(30mm thk)
PQR Material : 1. Pipe - ASME SA 333 and 2. Flange : ASTM A350 LF2
 
Query:
Is it mandatory that Qualification has to be done only with a ASME Material?
If ASTM Material is used for qualification, then WPS will be qualified only for that particualr Material and cannot be Qualified as P1 Material. Please provide all reference from Code for justification.
 
Hope to see that i was able to communicate properly with regard to raised query.
 
Expecting as usual response from all sides.
 
Thanks & Regards
Vino-Doha
