Hello
Can you help me to find requirements for u-bends pdht in heat exchangers acc to ASME VIII div 1 ? I have tubes with o.d. 25 x 2,6 mm and radius 37,5 mm. Material is P265GH acc to European Norm. I found some information in this ASME, but I lost it.
Thanks in advance

Hi
I am preparing a heat exchanger documentation for new exchanger based on old documentation. The heat exchanger is in Poland, and the old documentation is from Italy. In nozles table I have flanges description: 4" 150# WN-RF-R9-sch.40 and 3" 150# WN-RF-R9-sch.40.
Do you know what R9 can mean...
Hello All
I prepare a floatong head heat exchanger calculatiobn acc to ASME VIII part UHX-14 with Visual Vessel Design program
In tubesheet calculation I have a position: "correction factor to account for radial differential thermal expansion fT"
Do you know what value should be written ? I can...
Hi
It is possible, that I will make design of horizontal pressure vessel with boot for potassium hydroxide (KOH), hydrofluoric acid (HF), hydrocarbons.
It is a reconstruction design, old tank has more than 40 years. The tank is made from SA-515 gr 70, and had a post weld heat treatment.
Do you...
Hello All
I have in data sheet for storage tank acc. to API 650 a flanges forgings with SA182-316Ti material
Flanges acc. to ASME B16.5
I can't find this material in ASME SA182 standard
Is it a "shortcut" or I have old version of this standard ?
What is full name of this material ?
I dont have...
Hello
I have storage tank made from SA516 gr 60 material. Tank covered by API 650. Please look at my inerpretation of impact testing energy value. It is important for me.
API 650 twelfth ed. 2013
SA516-60 in table 4.4b -> material group III or IIIA
Table 4.5a -> min value 20J
Thanks in...
Hello All
I am preparing non destructive examination scope for tank designed acc to API 650 with bottom cone. I can't find NDE requiremnents for bottom cone in API 650 and ASME V. Maybe I didn't see it. Do you know where it could be found ?
Thanks in advance
Hi
What is correct forging thickness (see piping flange sketch) ? dim A, or B or C.
It is important for me for strength calculation
Thanks in advance

Hello All
I have floating head heat exchanger, my question is about split ring connection
Floating head is acc. to TEMA STYLE "B"
Design is based on TEMA, but it is no reqiurement
Usually split ring connector I saw as partial ring with 4 threaded holes, see sketch.
My question are (see...
Hello
Do you have any simple way (program ) to calculate heat exchanger insulation thickness ?
I have shell temperature 180 deg C, shell diameter OD 610mm and I am looking for standard insulation thickness (using for example mineral wool) My preliminary assumption is temperature 30 deg C on...
HI
I am preparing calculation with ASME 8 div 1 concerning tubesheet. I forgot wthat does it mean: "Tube expansion depth ratio"
Value is not in inches / mm
Could You write small explanation ?
Thanks
Hello
Could you help me, how to calculate desgn stress in design temperature for bolts ?
I am praparing calculation for heat exchanger and I must use material A2-70 for bolts, but I don't have it in material library. I calculated design stress for test and 20 deg C condition (based on EN...
Hello :)
I am new here, and I have question, forgive my poor english
