20" pipe purchased back in the 50's. P.O. states "substandard", and a related document mentions "Condition I, Condition II, and Spiral Weld" pipe. Now I understand spiral weld, but what is Condition I and Condition II.....????
Thanks
I have used a 1500W "water heater element" as found in standard residential water heaters. It heats the water just fine. I was looking at options to where I didn't have to go with an internal element. The more I think about it, the more I am inclined to work around that issue. Budgetarily...
I have a 15.5-gallon SS304 drum that has an O.D. of 16.125".
I want to fill it with 10-gallons of 70F water and heat it to 200F using a 120V _____watt band/drum heater.
Like to accomplish this in 1-hour.
Drum is atmospheric pressure.
Can somebody fill in the blank ________watt...
C6+ is .22%.........approx 250MMSCFD total gas flow (800 psig/50F). Some early calcs showed in the neighborhood of 3000 bbls/day NGL's. We are trying to figure out if it should be stored in tanks and trucked to buyer, or pipelined alongside the main gas line (225 miles 24"). It's out west and...
Let's say you have a 24" pipeline in Utah. The frost line is 24" deep. Top of pipe is 36" deep. I want to estimate a worst case scenario soil temperature. Any thoughts or comments ?????? Websites that publish average soil temperatures...????
Thanks
I will say good luck. Due to the fact that industry is booming, it's mighty hard to get shop floor time in most PV shops in Houston these days. If you have a lot of lead time, then probably no problem. Again, good luck!
I used to do a lot of steamblowing. Back in the day, there was not as much concern as to what grade of pipe was used, however wrong that may be. More recently, much more consideration is given to proper engineering in this endeavor. In sections of the temporary steam blow piping that are...
I used to work for a company that performed steam blows, chemical cleaning, etc... There are basically two kinds of steam blows...high-pressure exhaustive, and low-pressure high-velocity continuous. On continuous blows, there is a device called a target inserter that allows targets to be...
I have a customer that has a piping specification that refers to ball valves as "regular port" and "full port". Now, I'm very clear, when referring to "full port", as to what I'm referring to. On the other hand, when someone refers to a ball valve as "regular port", what specifically are we...
Just a quickie....has anyone used or developed a down & dirty Excel project scheduling spreadsheet? One that would generate a Gannt chart? Certainly not with all the features of MS Project or Primavera, but something useful?
Thanks,

MJC,
I agree. We're just getting a lot of "deer in the headlight" looks from drafting and design on these in particular. I mean, 16", on a six-foot diameter shell does, indeed, look "robust". The calcs for shear, bending, and weld stresses are WELL within limits using an impact factor of 4...
I am looking for some direction in finding documentation regarding lifting trunnion design for pressure vessels. In particular, I'm trying to educate myself on the common practices involving lifting trunnions. My company generally utilizes lifting "lugs" when practical, however, we have a...
Has anybody ever needed to have a Tee fitting as part of an ASME code vessel......say, a 16" dia. vertical vessel about 8' tall with a 16" Tee (branch out the horizontal axis)....??? If anyone is a COMPRESS guru, I can provide details...........
Thanks,
CW3
That's what I thought, however, I was looking at some reports and compared values against the drawing. It appeared that the OD was used.....hmmmmm. I also understand the relationship between "mean radius" and vessel heads, but the shell issue is still a bit unclear.
I'm wanting to double check on an item or two pertaining to nozzle external forces & moments in cylindrical vessels......the term Rm = mean radius of shell (inches). Am I to take this as the O.D. on a straight cylidrical vessel?? I'd also like to include in a spreadsheet, calculated values...
SRE:
Thanks. That's a nice document (DOE). The h-s Mollier Diagram prints out pretty good.
This forum is such a great way to find/share information. It's especially satisfying to know there's so many peers out there that take the time and the interest in acquiring and spreading their...
