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.

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.
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...
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:

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...
Hi Folk! Good Day!
This is regarding the 2:1 Ellipsoidal dish EFE & end heat treatment, dish end nominal thickness is 20mm and material is SA-516 Gr. 70 N.
As per the code clause UCS-79 (d) is applicable, which states “if dish end formed with cold forming and determined the extreme fiber...
@SnTMan
UW-13 (i) talk about the tapper transition for the flange and pipe weld join in case if the pipe and flange are not on same schedule. Its already under considered on other nozzles but on this case it does not apply.
My concern is about to maintain the both flange & pipe at schedule -60...
@ironic metallurgist
Thank you for your valued feedback my dear, concern is not about required thickness, infact it is about the pipe inside machining.
Vessel pump vendor assembly is unable to go through the Schedule-80 pipe. so we want to utilize the schedule-80 and then machining to maintain...
