WPS Qualification / Pressure Vessel / ASME Sec VIII, Div 1

[Vino Varghese]

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

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).

Hi,

Please refer UG-84(h)(2) of ASME Sec VIII Div.1'Ed'2010.

If impact testing is required in weld & HAZ when required by UCS-67,
the following shall apply.

For vessels constructed to the rules of part UCS, the test plate
material shall sitisfy all of the following requirements relative to
the material to be used in production.

(a) be of the same P-Number and Group Number;
(b) be in the same heat treated condition; and
(c) meet the minimum notch toughness requirements of UG-84(c)
(4) .......................

Means, one way or other, If you are using LTCS material for production
and requires notch touchness of weld and HAZ then the base material
used for Procedure shall be of same P No..(You can use ASTM A333 Gr.
6(P1G1) to ASTM A350LF2(P1G2) procedure) but you can not use ASTM A106
Gr.B even though it is P1G1 since it "is not the same heat treated
condition" as that of A333 gr.6.

Hope this will clarify!


Cheers!

Raj

Dear Raj,

 

Thanks for the information, but still the query is not answered.

 

There is no Impact Test requirement for our Vessel.

 

Now can you please guide, whether i can prepare a WPS with an ASTM Material.

 

Thanks & Regards

Dear All

 

I have a question that “  we have established AUTO TIG ( ORBITTAL ) WPS on 2”  OD x 1.6mm Wall Thickness on SS316L as per ASME 31.3 “    so now on this what will be the range  in terms of Wall Thickness and Tube OD.

 

Thanks

Yes, You can use ASTM materials qualified PQR for ASME materials
welding.

No restrictions as per ASME sec VIII Div-1 (Refer QW-28) or ASME Sec-
IX(Refer QW-420).

"If an unlisted base metal has the same UNS number designation as a
base metal listed in table QW/QB-422,
it shall be considered as assigned to that P-Number or P-Number plus
Group Number. However, only base metals listed in table QW/QB-422 with
minimum tensile strength values may be used for procedure
qualification test coupons".

Cheers!

01. If it is butt weld (AUTO TIG) range qualified shall be 1.5mm to 3.2mm (for WPS Diameter is not an Essential variable.you can use for both plate and Pipe) 02. But if it is a fillet weld (Orbit welding) tube to tube sheet and if your specimen as per QW462.4(d),there is no limit. it will be qualified for   "All fillet sizes on all base metal thicknesses and all diameters " as per QW452.3

You can recertify ASTM material to ASME SA material   as a manufacturer per UG-10, making sure that it conforms to that SA material

Hi Vino,

 

I you go strictly by the interpretation of ASME Sec-IX-2010 (QW-420) and ASME Sec-IX-2007 the answer is no for ASME Sec-VIII, DIV-1 construction. The rationale is as follows:-

• Reference Code : ASME Sec IX, Edition 2007, Add 09

• Material of Construction: SA 516 Gr 70N(30mm thk)- P No 1 Group No 2
• PQR Material : *1. Pipe* - ASME SA 333 --(P No 1 Group No 1) and *2. Flange* : ASTM A350 LF2--Not a listed material in ASME Sec-IX. Note  SA-350LF2 is a listed material in Sec-IX as PNo1 Gr 2 , while A-350 is not.
  

However as per SA-350 (Sec-II, Part,-A, preface), the essential difference with A-350 is as follows:-

 

• (Identical with ASTM Specification A 350/A 350M-02b except for the deletion of 6.1.2 and 14.1, revision to 14.2.5, and test reports have been made mandatory.)

Hence should you have all the required paperwork for  A-350 LF2 base metal, you may equate this  material to SA-350LF2 (provided the vessel is not a code stamped vessel) and there's absolute urgency to ask for waiver.

 

However to avoid future controversy it would wise to requality the procedure to both SA materials.

 

Thanks.

Dear Vino,

Please have a look at Qw-420.2 which allows you to use ASTM material for qualification.

In 2009, changes were made and S no. was removed from ASME Sec ix, "Base materials previously assigned S no were reassigned the corresponding P no or P no plus Gr no"

ASTM material shall have same P no as assigned to ASME material (SA333 Gr6 - P1 Gr1 & A350 LF2 - P1 Gr2)
