Better u can apply ER 309LMo and Second Layer ER 316L.

anup, if design code is b31.3 then how could u combine with pwht and without pwht wps? -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Dear Experts, In our project, we have to establish a  WPS /PQR for A333 Gr 6 Pipe (P-1,Group-1) and Flanges A350 LF-2 (P-1,Group-2).   Process - GTAW+SMAW (with ER 70S-2 and E7018-1). How to conduct/establish one combined PQT with P-1,Group-1 to P-1,Group-2 ??  Can we make two PQT separately of below options :- One Pipe to Pipe in 6G position and other any Plate to Plate in 4G/3G position of which Tensile Strength 70 ksi) - Is it acceptable  as per ASME Sec-IX? Please clarify.   Thanks in advance, R.K.Samanta

To qualify as per Sec IX,  for the above mentioned range you need to combine two PQR while making the WPS. First PQR shall have T ( base metal thickness ) less than 10mm which will qualify the WPS from 1.5 mm to 2T. Second PQR shall be made on say 30 mm Base metal thickness which will qualify the WPS from 5mm to 60 mm. These two PQR can be combined while making a single  WPS provided all other essential variables are the same for both the PQR except for T. If impact test requirements are there, then all the supplementary variables need to be considered.

Dear Member!!   As you said, ASME code  Sec VIII Div 1 it´s applicable to design heat exchangers, but from the point of view as a pressure vessel, that means the capacity of the equipment to contain the work fluid at operating condition of design (pressure, temperature, metal thickness, material and weld efficiency)   By the other hand, you have another factors to consider in the design as: number of tubes, diameter of tubes, longitudes, diameter, material of tubes. As a guide to define this parameters, there is the TEMA (Tubural Exchanger Manufacturers Association, Inc.) standards whose can be very useful.   Please visit http://www.tema.org/index.html to consult about software and codes   Regards     Miroslav   Tadic Ingeniero  de Integridad CEE Gerencia de Producción - Mantenimiento YPFB Chaco S.A.

Ans1:yes or u can send justification as per ASME. Ans2: yes if impct conducted then all supplimentry variable applicable. -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.
