@CuMo Its floating head. Yes mandatary to do strength welding. My query is pertained to welding material between tube sheet cladded face material (CrNi 90/10) to tube (SB-111 , UNS C70600 (CuNi 9010)).

Hi All, Appreciate to have expert opinion from welding and material perspective. Case details: Heat exchanger tube to tubesheet weld Joint Tube sheet base material is SA-266 Gr. 2/4N Which have explosion bonded Cladded face (10mm) with - CrNi 90/10. Tube material = SB-111, UNS (C70600) (CuNi...

SnTMan, Thank you for your clarification, your explanation is legit and cross verified it correct! :) This is default nozzle reinforcement limits which software is calculating based on the head thickness & RF pad thickness. and Yes you are right we can define the nozzle reinforcement limits.

@SnTMan I always got positive firm feedback from you which really help me alot. Thanks for your valued time. Coming to the point: 1. Yes sketch attached : 2. Contacted to support team and so far no positive response received with demonstrative calculation. 3. Your point gave me an idea of...

@some Curious Guy : Thank you for your valued feedback. I actually already inititate the clarification to software support team and even they dont know yet the basis and same populated ahead to their USA based developer and validation team. Regarding geometrical shape of welds with different...

Kindly advice on it.

Hi Folks! I'm performing a nozzle calc which is "Set in" , NPS-2" with below details and I am unable to understand that from where PV Elite is considering "Ar Lost" value and subtracting from the A41 and A42. This nozzle is located on vessel dish with below details: Outer weld size (neck to...

Gents, I'm little confused about the how compress is giving exemption of impact test at -55 deg. F by simply refereeing the clause UCS-(b)(1)(b). My governing thickness is = 3.810" Nozzle type = Heavy barrel Nozzle material = SA-105N Nozzle size = NPS-24" Shell thickness = 4.250" Required...

If your client is happy to see the rainbow, ask him for the extra money for FEA. Since FEA is quite time taking activity and eventually will be involving the extra manhours. Let him ask why it is particularly required? Even API is clearly providing the all manual calculation reference.

@Krausen, I do agree with you but the situation is not like that in this case. @SnTMan, Thanks for your valued feedback, MDMT is 0 deg. c. Please advice ahead based on MDMT.

Sorry I forgot to mention the MDMT = 0 deg. C

Hi Folks! Good day! I have a one body flange (WNRF)and blind flange (NPS-72") in accordance with ASME Sec VIII Div. 1, Appendix-II. The material of flanges are SA-105N (Curve-B) I'm pretty confident that blind flange of below sketch (150mm) thickness with SA-105N material (Curve-B) shall be...

@r6155 Its higher than 5%. What will happen if we maintained higher time than MTR?

Its totally depend on plant to plant and varied based on specification to specification which acceptable to different region of end user. In Gulf most of the time, below are the requirement that we encourage to utilize: Spares for Commissioning & Start-up: 1- Bolting – 10% of each size (2 sets...

As per B16.5 SA-105 flange can be withstand up to maximum -29 deg C. Hence as per your desired -46 deg C MDMT it shall not be work. Further to regarding the normalized / fine grain practice, this has been revised in ASME SEC VIII Div. 1 2019 ver., now the SA-105N is coming under the curve B...
