Re: [MW:23841] ASME Sec VIII, Div 1, Pressure Vessel/ Dish End

I do agree with Mr. Prakash partially. The initial raised question can be addressed as "Dear Experts" but  subsequently its difficult to maintain the same. Just as an Eg: A third person enters the group after the 14th mail conversion, he won't be in a position to understand the last query if its addressed as "Experts". He might have to run through all the previous conversations. Further, the person who raises the query directly can response if a clarification against his query is required else if it is addressed as "Experts", he might get lost or could get unnoticed. I think the exchange of forum to individual is OK and should be seen in a lighter note. That's my opinion.

Regards, Vino

It should be addressed as Dear Experts/ or Nothing. Just put up the point for discussion and ask for a response.
While replying also, you will answer to the point raised, not to the person raising the question.

Hope people who have joined new understand that every individual of the group must get benefitted by the discussion.
As far as possible raise a point and ask for response whether right or wrong.
Individual problems must best be sorted out individually. The group will only help you understand the subject with more information and standard references, but will not solve or give solutions to problems. At most we may agree or disagree on a point.
Hope all members will follow the above and make this forum a high level discussion forum and exchange of info rather than a discussion between two individuals......

Dear Ajay,
Hi to all,
i am also facing same type of issue.

i have bought a tubesheet for heat exchanger, CS(SA266Gr2) base metal with SS316L(SA240) clad plate 10 mm thick.
My AI said, need to get the PDR from the vendor. But the vendor is no stamp holder.
ASME VIII Div.1 - UW-27(2), explosive bonding included in pressure welding process and 
added in ENDNOTES (70) - explosive welding—a solid state welding process wherein coalescence is produced by the application of pressure by
means of an explosion.
and another thins is clad plate is for corrosive resistance only, design calculation did not considered this clad plate thickness.

please explain to me, what are the acitivities required to proceed without PDR.

Thanking you

In my opinion still there is no need of PDR, Following is the justification:
 
1. Reference: UG 11(b)......."All such parts shall be made of materials permitted under this division".
Cladded plates will be certified as per either SA 263/264/265, which complies to the material requirement permitted by ASME Sec.VIII Div.1 as per Clause UCL 11(a). Please note that the UG11(b) is for "Cast, Forged, Rolled, or die Formed Non-Standard Pressure Parts" & not for the Raw Materials (In our case it's clsad plate).
 
2. Reference SA263/264/265, Section 14 "Repair of Cladding by welding": Please note that even repair of defects in clad is allowed by welding, provided it meets all the requirement stated in Clause 14.1.1 to 14.1.6. The point to be noted is that there is no restriction on the area of repair i.e. the plate manufaturer can still repair the clad throught the length of the plate and still can certify the plate. So, no PDR is asked in this case. And the same case is applicable to the splice joint of SS plate prior to bonding.
 
However, you need to have all the documents in place similar to what asked for the repair i.e. WPS/PQR & WQR in accordacne to Sex.IX (Clause 14.1.2) etc. You can even ask for higher extent of examination, as it is upto the purchaser. 
 
3. I can understand the conserns of AI. They would be more concerned about the integrity of the weld which can be taken care by proper evaluation of documents, using proper consumable, using qualifeid welders, and testing (PT) the weld . However, the plates itself are acceptable with certain defect to an extent, such as lamination. Please note that the more emphasis shall be on the properties & bonding of the plates.
 
4. We had used the clad plates with similar issue and with no PDR, in my previous organisation. The base plate size was 3050 x 12000mm. And getting the SS plate in the same size is not always practical. You can also check with your clad plate supplier, as they would had surely supplied plates with similar issue without PDR.
 
I hope, this would be justifying. And still, If AI is confirming that PDR is required, then i would be keen to know as per which clause of the standard. Looking forward to have your response.

The Rewording you have provided is absolutely correct.
I have consulted our A.I and he confirmed that the PDR is required.
 
Still i am not totally convienced. I think you can put more light by supporting similar real time work in past.

Rewording your query, correct me if i'm wrong,
 
"The clad plate will be in 2 pieces welded together which will be bonded together with base plate of SA516 Gr.70 (Single piece). After the explosion bonding, then the plate will be formed to make head."
 
If this is the case, then you don't need to have PDR, as i believe the plates (Base+clad) will be prodcued & certified as per SA-263/264/265 and then formed into heads. Please refer UCL-11 (a).
 
If still in doubt, then consult your AI.

Dear Karthik and All,
 
Thanks for the reply. Appreciate to see your quick reponse.
 
I have 1 more Question for you.
 
The manufacturer does not have a single piece for the Cladded part(3mm) and they intent to achieve this by joining 2 plates by welding. The Base Material(27 mm) Plate is Seamless for the Dish End.
The Dish End is achieved by Explosion Bond Process and the Base Materials is 27mm, SA 516 Gr.70 + 3mm Clad Plate(Inclloy 825).
The disbond shall be checked by UT.
 
As there will be Welding involved, should not we request for a Partial Data Report signed by a A.I at the Manufacturer Shop before it is delivery at our Fabrication Shop?
 
Thanks

The Partial Claddded Area has the -
Base material = 27 mm thickness , SA 516 Gr. 70
Clad Material =  3mm min. , Incolloy 825.
 
One of the Dish End is a Cladded part(Explosion Bond Method) which we are planning to off load work to a "U" Stamp Manufacturer Shop due to limited forming availablity at our Fabrication Facility.
My Question -
1) Does this shop need to have ASME "U" Stamp? - No need. (UG-11 (b) )

2) Do we require a Partial Data Report from this Manufacturing Unit duly signed by Autorised Inspector? - No need.Manufacturer of the
part shall furnish identification in accordance with UG-93.
You have to certify the Dish end as you are the U stamp holder and manufacturer as per
(UG-11 (b) ) and UG-79 and submit the report and related documents to AI for acceptance.

3) Do we require this Manufacturing Unit to be Approved by requesting them to submit Pre-Approval Document? - As per your Quality System.

4) What all min. Documents are required to be submitted in accordance to ASME Sec VIIII Div 1. - If for dish end only means,Material certificates,Dimension Reports,If there is any Heattreatment applicable...Heat treatment report etc.,
If for the Whole vessel,it will be as per your quality manual and ASME Sec.VIII,Div.1-Appendix-10,10-3 (Record Retension)
5) The Contract for this Vessel was signed by Client on June 2010. Can we use ASME Sec VIIII Div 1, 2007 with 2009 Addenda or we have to follow ASME 2010? - You can use ASME Sec VIIII Div 1, 2007 with 2009 Addenda
 
Please do provide relevant Clause from ASME supporting the above Queries.
 
Hope to see as usual opinion. Also someone can share QAP of similar use.(SA 516 Gr. 70 + Clad , Incolloy 825.) and relevant WPS. - You mean ITP? it shall be prepared by you as per the drawing and scope of work.
For WPS..please send the doubts in preparation of WPS.we can assist you.

Re: [MW:23836] ASME Sec VIII, Div 1, Pressure Vessel/ Dish End

Hi,

Only if dished has a long seam then PDR need to be supplied by the part manufacturer. For explosion bonding no PDR is required, only certification need to obtained as per SA263/264/265 as applicable.

Dear Ajay,
Hi to all,
i am also facing same type of issue.

i have bought a tubesheet for heat exchanger, CS(SA266Gr2) base metal with SS316L(SA240) clad plate 10 mm thick.
My AI said, need to get the PDR from the vendor. But the vendor is no stamp holder.
ASME VIII Div.1 - UW-27(2), explosive bonding included in pressure welding process and 
added in ENDNOTES (70) - explosive welding—a solid state welding process wherein coalescence is produced by the application of pressure by
means of an explosion.
and another thins is clad plate is for corrosive resistance only, design calculation did not considered this clad plate thickness.

please explain to me, what are the acitivities required to proceed without PDR.

Thanking you

In my opinion still there is no need of PDR, Following is the justification:
 
1. Reference: UG 11(b)......."All such parts shall be made of materials permitted under this division".
Cladded plates will be certified as per either SA 263/264/265, which complies to the material requirement permitted by ASME Sec.VIII Div.1 as per Clause UCL 11(a). Please note that the UG11(b) is for "Cast, Forged, Rolled, or die Formed Non-Standard Pressure Parts" & not for the Raw Materials (In our case it's clsad plate).
 
2. Reference SA263/264/265, Section 14 "Repair of Cladding by welding": Please note that even repair of defects in clad is allowed by welding, provided it meets all the requirement stated in Clause 14.1.1 to 14.1.6. The point to be noted is that there is no restriction on the area of repair i.e. the plate manufaturer can still repair the clad throught the length of the plate and still can certify the plate. So, no PDR is asked in this case. And the same case is applicable to the splice joint of SS plate prior to bonding.
 
However, you need to have all the documents in place similar to what asked for the repair i.e. WPS/PQR & WQR in accordacne to Sex.IX (Clause 14.1.2) etc. You can even ask for higher extent of examination, as it is upto the purchaser. 
 
3. I can understand the conserns of AI. They would be more concerned about the integrity of the weld which can be taken care by proper evaluation of documents, using proper consumable, using qualifeid welders, and testing (PT) the weld . However, the plates itself are acceptable with certain defect to an extent, such as lamination. Please note that the more emphasis shall be on the properties & bonding of the plates.
 
4. We had used the clad plates with similar issue and with no PDR, in my previous organisation. The base plate size was 3050 x 12000mm. And getting the SS plate in the same size is not always practical. You can also check with your clad plate supplier, as they would had surely supplied plates with similar issue without PDR.
 
I hope, this would be justifying. And still, If AI is confirming that PDR is required, then i would be keen to know as per which clause of the standard. Looking forward to have your response.

Dear Ajay,
 
The Rewording you have provided is absolutely correct.
I have consulted our A.I and he confirmed that the PDR is required.
 
Still i am not totally convienced. I think you can put more light by supporting similar real time work in past.
 
Hope to hear more information regarding the same.

Rewording your query, correct me if i'm wrong,
 
"The clad plate will be in 2 pieces welded together which will be bonded together with base plate of SA516 Gr.70 (Single piece). After the explosion bonding, then the plate will be formed to make head."
 
If this is the case, then you don't need to have PDR, as i believe the plates (Base+clad) will be prodcued & certified as per SA-263/264/265 and then formed into heads. Please refer UCL-11 (a).
 
If still in doubt, then consult your AI.

Dear Karthik and All,
 
Thanks for the reply. Appreciate to see your quick reponse.
 
I have 1 more Question for you.
 
The manufacturer does not have a single piece for the Cladded part(3mm) and they intent to achieve this by joining 2 plates by welding. The Base Material(27 mm) Plate is Seamless for the Dish End.
The Dish End is achieved by Explosion Bond Process and the Base Materials is 27mm, SA 516 Gr.70 + 3mm Clad Plate(Inclloy 825).
The disbond shall be checked by UT.
 
As there will be Welding involved, should not we request for a Partial Data Report signed by a A.I at the Manufacturer Shop before it is delivery at our Fabrication Shop?
 
Thanks

Re: [MW:23836] Tensile testing

Did u use extensometer or not?
You have to construct 0.2% offset on the strain axis and get the 0.2% yield strength. Probably ur software would have that option!

2015-10-29 19:13 GMT+04:00 Padmasanker S <padmasanker87@gmail.com>:

Dear all,

Please refer to attached stress -strain graph obtained during tensile testing of SA 106 Gr B pipe.

While performing tensile testing of SA 106 pipes for Div 1 vessels ,we were not getting yield point even though required tensile strength is obtained.

The specimen were taken in both  transverse and longitudinal direction from half thickness.

Kindly share your experience  in finding the root cause..

Please inform if any further details is required for clarity.

Reference SA263/264/265, Section 14 "Repair of Cladding by welding": Please note that even repair of defects in clad is allowed by welding, provided it meets all the requirement stated in Clause 14.1.1 to 14.1.6. The point to be noted is that there is no restriction on the area of repair i.e. the plate manufaturer can still repair the clad throught the length of the plate and still can certify the plate. So, no PDR is asked in this case. And the same case is applicable to the splice joint of SS plate prior to bonding.
 
However, you need to have all the documents in place similar to what asked for the repair i.e. WPS/PQR & WQR in accordacne to Sex.IX (Clause 14.1.2) etc. You can even ask for higher extent of examination, as it is upto the purchaser. 
 
3. I can understand the conserns of AI. They would be more concerned about the integrity of the weld which can be taken care by proper evaluation of documents, using proper consumable, using qualifeid welders, and testing (PT) the weld . However, the plates itself are acceptable with certain defect to an extent, such as lamination. Please note that the more emphasis shall be on the properties & bonding of the plates.
 
4. We had used the clad plates with similar issue and with no PDR, in my previous organisation. The base plate size was 3050 x 12000mm. And getting the SS plate in the same size is not always practical. You can also check with your clad plate supplier, as they would had surely supplied plates with similar issue without PDR.
 
I hope, this would be justifying. And still, If AI is confirming that PDR is required, then i would be keen to know as per which clause of the standard. Looking forward to have your response.

Dear Ajay,
 
The Rewording you have provided is absolutely correct.
I have consulted our A.I and he confirmed that the PDR is required.
 
Still i am not totally convienced. I think you can put more light by supporting similar real time work in past.
 
Hope to hear more information regarding the same.
 
Thanks & Regards
Vino P Varghese

    Rewording your query, correct me if i'm wrong,
     
    "The clad plate will be in 2 pieces welded together which will be bonded together with base plate of SA516 Gr.70 (Single piece). After the explosion bonding, then the plate will be formed to make head."
     
    If this is the case, then you don't need to have PDR, as i believe the plates (Base+clad) will be prodcued & certified as per SA-263/264/265 and then formed into heads. Please refer UCL-11 (a).
     
    If still in doubt, then consult your AI.

    Dear Karthik and All,
     
    Thanks for the reply. Appreciate to see your quick reponse.
     
    I have 1 more Question for you.
     
    The manufacturer does not have a single piece for the Cladded part(3mm) and they intent to achieve this by joining 2 plates by welding. The Base Material(27 mm) Plate is Seamless for the Dish End.
    The Dish End is achieved by Explosion Bond Process and the Base Materials is 27mm, SA 516 Gr.70 + 3mm Clad Plate(Inclloy 825).
    The disbond shall be checked by UT.
     
    As there will be Welding involved, should not we request for a Partial Data Report signed by a A.I at the Manufacturer Shop before it is delivery at our Fabrication Shop?
     
    Thanks 
    Vino  Varghese

    Hi,
    Please find below my suggestions as marked in RED.

    1) Does this shop need to have ASME "U" Stamp? - No need. (UG-11 (b) )

    2) Do we require a Partial Data Report from this Manufacturing Unit duly signed by Autorised Inspector? - No need.Manufacturer of the
    part shall furnish identification in accordance with UG-93.
    You have to certify the Dish end as you are the U stamp holder and manufacturer as per (UG-11 (b) ) and UG-79 and submit the report and related documents to AI for acceptance.

    3) Do we require this Manufacturing Unit to be Approved by requesting them to submit Pre-Approval Document? - As per your Quality System.

    4) What all min. Documents are required to be submitted in accordance to ASME Sec VIIII Div 1. - If for dish end only means,Material certificates,Dimension Reports,If there is any Heattreatment applicable...Heat treatment report etc.,
    If for the Whole vessel,it will be as per your quality manual and ASME Sec.VIII,Div.1-Appendix-10,10-3 (Record Retension)

    5) The Contract for this Vessel was signed by Client on June 2010. Can we use ASME Sec VIIII Div 1, 2007 with 2009 Addenda or we have to follow ASME 2010? - You can use ASME Sec VIIII Div 1, 2007 with 2009 Addenda
     
    Please do provide relevant Clause from ASME supporting the above Queries.
     
    Hope to see as usual opinion. Also someone can share QAP of similar use.(SA 516 Gr. 70 + Clad , Incolloy 825.) and relevant WPS. - You mean ITP? it shall be prepared by you as per the drawing and scope of work.
    For WPS..please send the doubts in preparation of WPS.we can assist you.

      Dear All,
       
      We have a Partial Cladded Vessel("U" Stamp Vessel) which we are intend to fabricate at our Manufacturing shop and is designed for Sour Service.
      The Overall thickness is 30 mm.
       
      The Partial Claddded Area has the -
      Base material = 27 mm thickness , SA 516 Gr. 70
      Clad Material =  3mm min. , Incolloy 825.
       
      One of the Dish End is a Cladded part(Explosion Bond Method) which we are planning to off load work to a "U" Stamp Manufacturer Shop due to limited forming availablity at our Fabrication Facility.
