Please refer the following ASME BPV interpretation on a similar case although for ASME Sec-I, just for your reference: Standard Designation: BPV Section I Edition/Addenda: Para./Fig./Table No: Subject Description: Section I, P0-10.1.1, Recertification of Materials Date Issued: 12/07/1992 Record...

Amit217, Please refer to the general note mentioned under Table UG-84.6," Each specimen shall be full size, or the largest subsize specimen that may be removed from the available material thickness as required by UG-84(c)(2)". Thus it should be 7.5 mm sub-size specimen.

Smart143, The above base metal limit is applicable for groove joints and not for fillet welds. for fillet welds the range of qualification is , "All fillet sizes on all base metal thicknesses and all diameters" as per table QW 451.4. As far as the general note is concerned, it addresses the...

As far as the base metal thickness range for filet welds are concerned, fillet weld of any size is allowed in all base metal thicknesses and all diameters as per table QW-451.1, When WPS is written for groove joints, the base metal "T" is not considered as a variable for fillet welds although...

Hi, If I interpreted UCS-66(a) correctly, when a component is exempted from impact testing as per UCS-66(c)(4),wonder if further evaluation as per fig.UCS-66 is really required. If i read the scenario in conjunction with the interpretation, LWN flanges are excempted from impact testing and...

Hi, AD-Merkblatt requires harmonized materials for construction of pressure vessel as per section W0. W1,W2, please note that the use of AD 2000 goes together with PED Directive 97/23/EC. As per PED Directive , to use non -harmonized materials, such as ASME materials, you have to prepare PMA...

Yes, the question is pretty clear, but can't answer in yes or no because the Code requires the base material to be used for PQR as the same heat treated condition. Since you want to combine plates of two different heat treated condition, my concern is how the requirements of Code in terms of...

Heat treatment condition is an essential variable as per UG-84(h)(2)(b)when impact test is a requirement.

Hi, Sounds logical . Given the scenario, impact specimen shall include HAZ samples of both the sides (N and Q&T)to cover more than one HT condition

QW407.2 supplementary variable applies here due to impact test, the code requires the temperature to be "essentially equivalent to that encountered in the fabrication ". The temperature required for P-1 material is 595 Deg C(min) as per UCS 56,Normally the above clause is more relevant when...

Thanks for your inputs. The proposal is correct, need to supplement a test plate having impact tested to the requirements of Div.1 2013 Edition. This also affect all the PQR of thickness more than 38 mm qualified previously to the requirements of UG-84 , now to be supplemented with two sets of...

Hi Guys, Could you please share your views on below, A PQR is qualified with impact test the requirements of UG-84(g) edition (2007), this edition requires only one set of impact test HAZ specimen to be tested. Whereas the Ed 2013 of Div.1 requires HAZ to be tested as per the new...

Thanks TGS4 and GenB for your view on this.

Hi, A vessel is designed for internal pressure of 4bar(g) and an external pressure of Full Vacuum (1 bar(g) as per ASME Sec VIII Div.1. There are two formula available for reinforcement calculation based on internal and external pressure in UG-37(c)&(d)of ASME Sec VIII Div.1. Wherein the...

The header box is manufactured as per ASME Sec VIII Div.1 Ed 2013 and the MOC is SA 240 UNS 31803 (Duplex SS), MDMT (-)29 Deg C Impact test is required for base material and Welding procedure as per UHA 51. The header box consist corner joints UW-12 Type 7 (category C&D) and category C(Nozzle to...
