Hello All,
Because I handle boiler and other ASME issues, I was asked a question today about air unloading chemicals from rail cars and tanker trucks. They asked: "Why aren't those vessels ASME stamped if they operate at 45 psig?"
I'm continuing to investigate, but hoped that someone here has...
All I've been doing for the last couple of months has been project proposals and RFQ packages. I know, I know, "be happy I have a job", BUT I need some way to make this work more interesting until I get some of this stuff approved! It seems like it's all just clerical work!
I'm working in a relatively corrosive atmosphere and I have used coated copper tubing with some success in these environements.
I would sure like to have an option to use SS tubing or piping and use SS refrigerant specialties.
Any ideas?
Manufacturers?
I'm looking for a standard that governs the thickness and dimensions of angle face rings...
I know we've purchased them from fabricators for vacuum piping and large process water piping.
Any help out there?
Where do you think the Mechanical Engineering "hot beds" of activity are?
I think I know the standard places like Greenville, SC or Houston, TX but where else?
I'm not currently considering re-locating, but maybe, just maybe if there is a cool place where a lot of ME opportunities exist, I can...
I'm just wondering what everyone else thought about this thought:
When you're in school and have math, logic and science aptitude, you get pushed toward engineering or sciences.
Now, at least where I'm at, it seems that the engineering career has nothing to do with math or science --- maybe...
I'm looking for suggestions on the best reference articles to build a spreadsheet to model Yankee hood performance on tissue machines. We have a number of machines. We also have multiple hood types (once through vs. recirc). So I may have to build two models to accurately evaluate certain...
The pipe spec I'm using calls our Flexitallic (sp?) spiral wound gaskets for natural gas piping systems.
The gas supplier recommends using fiber gaskets. I have no problem with following the supplier's recommendations, but we have an existing system with the spiral wound gaskets installed...
I have a new application. It is essentially a copy of another installation in the same geographic area.
In the original installation some assumptions were made with regards to heat load from electrical gear. The actual chiller loads we have been seeing are about 70% of what we thought...
I'm working with some absorption units that have been crystallized and decrystallized A LOT. What are the long term effects of this? I know it's not good... I just need to know what to check on.
The operators can't operate the system.
Maintenance doesn't maintain the chillers.
My manager...
I'm trying to replace an existing shell and tube heat exchanger that was oversized by quite a bit, but want to make sure I'm not missing a better piece of equipment for this application...
Fluid:
Glycol (40%)
EWT - 85 F
LWT - 115 F
GPM - 2000
Steam:
60 psig
I think with the big delta T...
I just wanted to check if anyone had any ideas of what the new underground pipe treatment was to prevent corrosion. I have to install a small amount of underground pipe and think cathodic protection might be overkill.
The only real pipe that I know to apply is carbon steel pipe with coal tar...
Someone wants me to calculate how much temperature rise there is in a O2 system.
I am over thinking this calculation to the maximum because you can calculate the heat transferred to the pipe from solar heat gain and ambient conditions, but the cooler O2 gas should take that heat away and slowly...
I've just run across some of these in a power plant - but have never specified or installed one. I think I understand what they are used for - the flex connector isolates the relief valve discharge piping from the valve itself both from thermal movement and movement due to force.
Is there a...
I am modeling some steam piping in a stress program and need to input translational stiffness information on some expansion joints.
This is a typical problem I have run into before. I found some old catalog information, but I don't have good confidence in it.
Does anyone have any suggestions...
I am new to working in pulp mills and I am wondering about what the purposes of fiberlizers and mix pots are?
In the mill I am working in, it looks like the use the mix pots as line splitters.
The fiberlizers are on the discharge of the blow tanks in the pulp mill.
I have done web searches...
I am looking into purchasing these programs for help in designing some industrial duct systems.
Anyone out there have any reviews on the "user friendliness" of these programs?
I need some help.
I am just concerned that the demo may be easy to use, but using the program on a very large...
Hello everyone,
Thanks for all who have answer my questions on relief valves in the past. I have one more.
I have received bids on relief valves for a shell and tube heat exchanger. I requested that the valves be sized for full steam flow into the exchanger. The valves will relieve 60 psig...
I have a large heat exchanger with steam on the shell side and 30% glycol solution on the tube side. My big question is:
Can I pump a variable speed pump to this heat exchanger or is there some minimum flow I need to maintain?
I am planning on pumping in parallel (two 1800 GPM pumps, both...
