XL83NL,
K-factor should be about 0.20.
Flange material Monel 400 SB-564 N04400 - 1/2", 4", 6" and 8".
Thanks for the answer.
r6155, thanks for the advice.
XL83NL, thank you for your reply and I apologize if my question was superficial.
I meant to ask if there were directly tables for these combinations, leaving out the flange material and obviously providing different options for nut factor and tooling.
I will try to calculate the torque anyway by...
Hi,
We have to build a column in SA-516-70 internally cladded in SA-240-316L (3 mm) for colamination.
In the circumferential joints we would have to remove about 3 mm in the carbon steel base material because we will have to perform the weld overlay so that we have 3 mm undiluted, getting to...
Thank you for the answers.
EdStainless, why did you mention "If you bend on site"?
Don't we have to follow this requirement if we perform the bending in our workshop?
Hi,
We have to design and manufacture the following pipeline in accordance to ASME B31.3:
Is it possible to obtain a 1/2" 90° elbow (even long or short radius) from a bended tube SCH. 80 in ASME SB-165 N04400 (Monel 400)?
Thanks in advance
Thank you for all the answers.
Do you think that solid metal type gaskets are appropriate for these design conditions?
Could be a better solution to use stainless steel or soft iron gaskets instead of inconel 625?
TGS4 thanks for the clarification, I will follow these paragraphs.
I had not paid attention to the sentence "In the case where the stress limit is exceeded, the selected test pressure shall be reduced, but no lower
than the minimum test pressure as established in Part 8".
Unfortunatly...
Thanks Christine.
Do you have some advice regarding torque for mentioned plugs-gaskets material?
For example, we generally use a torque of 495 Nm for plugs of the same size made of carbon steel (SA-105 or SA-350 LF2 CL1) with soft iron gaskets.
How can we calculate the torque in the case of...
I absolutely agree with you, but unfortunately our customer does not think the same.
Often there are not many ways to explain to customers things that really make sense, and you just do it to save time.
Regards
r6155,
Design pressure: 3.45 barg
Design temperature: 149 °C
Header boxes material: SA-516 Gr. 60
No. 231 high finned tubes in SA-179
Why do you need these information?
r6155, correct, this is exactly what I mean for MAP vs MAWP.
TGS4, I have always interpreted the UG-99(b) VS UG-99(c) formulas this way:
UG-99(b) classic formula: 1.3xLSRxMAWP(or design pressure. LSR calculated for each component, lower governs.
UG-99(c): 1.3xMAP(of each component)-hydrostatic...
Hello,
We are designing an Air-Cooled in inconel 625 and I would like to ask you if you think that gaskets in inconel 625 are needed for plugs in plugsheet or if we can use another material.
And if so, which would be the requested torque for the plugs.
Design temperature: 427 °C
Design...
r6155, I believe that UG-34 is not applicable to the case mentioned.
TGS4, thank you very much for the detailed answer.
With reference to 46-3(d):
"Evaluation of the stresses during the test condition of Division 2, 4.1.6.2 is not required. However, such calculations may form the basis of a...
TGS4, I have few questions regarding the above quote:
[ol 1]
Is verification according to UG-44(b) mandatory even if the word "may" is used?
If used, can the parameters of the new edition 2023 code case 2901 be used as an alternative even if ASME Code has its own parameters in Table UG-44-1?
I...
Hi,
I would like to understand if it is possibile to obtain the MAWP and the MAP for a flanged cover type air-cooled API 661, with ASME VIII-1 as design code.
Generally, when air-ccoled has the flanged cover instead of plugsheet, we perform the finite element analysis in accordance to ASME...
Hi,
Is it possible to use (for a EN 13445 project) an integral tubesheet with hub from plate (es. EN 10028-3 P355 NH) without no test on hub?
For example ASME requires the tension test specimens on hub region.
Thank you
