Hello fellow PV collegues,
A long pressure vessel, U-stamped and Natl Board registered, has been completely fabricated, ready to ship to US. Due to shipping constraints, it is cut in two, cut edges prepared for welding on site by an 'R-stamp' qualified contractor, who also re-tests the vessel...
On the weekend, I brought the key at home, to do some design. My son passed me his computer. I installed build 6258 ok, but when trying to open it I get a window saying it found 'a security key emulator program'. I asked him (the expert) to look into this, he deleted a few files, but I keep...
Hello all, I have a question:
How should I approach the seismic design of columns inside perlite-filled cold boxes? The easy way would be to treat each column as free-standing; but would this be a safe approach, considering the effect of piping & other equipment attached, and the perlite? would...
With reference to thread 1259-187602, UG-44 is fine but, if you have to check the reinforcement of an opening on a pipe cap, your only choice is to treat the cap as a 2:1 ell. head, no?
I would appreciate some clarifications on wind speed and exposure categories, per IBC 2006.
For hurricane-prone regions, exposure C is to be used, with the appropriate wind speed. What about tornadoes? Is the max. wind speed limited to 90mph, and the exposure D, for tornado-prone regions? This...
Compress has modified the standard 'Jawad' formula from P=48M/(N*BC)-W/N, to P=48M/(N*BC)-(0.6-014Sds)*W/N, or P=48M/(N*BC)-0.6*W/N+Vv/N, when the IBC Code is used. I have not found any explanations in their manual; could somebody shed a light on this?
Thanks.
Ijust checked the expiry date for this code case, on the ASME website; it is nov/28/2003! Does anybody know if it has been renewed? I am using this case in my design and hell will break loose if it has expired on me!
Thanks for your input.
I have to check the pressure capacity of some vessels, built inItaly in 1980 and installed in Canada. Since I need to do an ASME design check, I have to find what material was used and dimensions. The name plates show some basic information, including registration numbers, five digits plus the...
I have a PV built in Germany in 1975; for bolt spec's they show 'DIN931, 24CrMo5'. What would be the equivalent ASME material?
For gasket, they show 'Jt300'only, and its thickness is 1mm.
What would be its m and y factors?
Thank you.
Does anyone know a design method to check the stresses on the dished bottom head to skirt connection(Other than FEA, of course), for cases where the skirt diameter is less than that of the vessel head?
For the first time ever, our North-American client, is asking for CE certification of dimple-jacketed vessels, in addition to ASME 'U' and NAT'L BOARD. The vessels have 15psi pressure(non ASME), and the jackets are at 100 psi. No problem for us to meet ASME/NAT'L BD, but CE is new to us. I have...
