Thanks guys; yeah, it is a shame we can never get the length right.:) Seriously, the alternatives are recipes for disaster, I have been there.
#1 Have the vessel fabricator do the field assembly himself. [Very expensive, union problems, possible sabotage].
#2 Vessel owner(O)has field work done...
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.
How can a fabricator TODAY repair/modify to say, the 1980 ASME Code, when his QC system is geared to TODAY's Code? Most of them throw away the 'obsolete', old Code editions/addenda.
The best approach would be to use TODAY'S Code, but the allowable stresses from the original 1980 Code; that would...
I took a quick look ar all API standards mentioned above. I do not see how these can be used to design horizontal tanks. They all specify they apply to VERTICAL tanks (see scope section); API 620 applies to tanks havind a single VERTICAL axis of revolution. Am I missing something?
Would a 12ft...
THEY (ASME) should take care of their own deadlines and update their website information.(http://cstools.asme.org/CodeCases.cfm) I do not have the time to go thru the formal PROTOCOL procedure.
Wow! I am lucky! The date of contract award is, you guessed it, the same as the expiry date of the code case, so I am 'off the hook!'
Thanks guys, for your input.
Guess what, my AIA do not know! they asked me to contact ASME. I will, and if I have news I will post them here. You are also right, the AIA near the installation site must be contacted to verify IF they accept THAT code case.
