Subject: Re: [MW:9359] ASME Sec VIII, Div 1, Pressure Vessel/ Dish End
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. PDR would be required if the heads are not in single piece. 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) If there is any tack welding to be done on the heads for lifting hooks etc., the vendor has to provide WPS,PQR & WQR as per ASME Sec.IX for approval to you who has the final authority for applying code stamp on vessels. Please refer U 2(B) (2), whcih states that "Some type of work, such as forming, NDE, & heat treatment, may be performed by others (for welding refer UW-26 & UW31). It is the vessel or part manufacturer responsibility to ensure that all work so perfomed complies with all applicable requirment of this division".
Refer UW-31 (C) last paragraph, which states that " Provided the work done under the provisoins of U2(b), it is not necessary that a subcontractor making such tack welds for a vessel or parts manufacturer be a holder of a code certificate of Authorization. The requirement oF uw-26(d) do not apply to such tack welds." 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. For WPS..please send the doubts in preparation of WPS.we can assist you.
