Group,
I am currently battling a mass of leaking chemical containers world-wide. 1 Liter HDPE bottles. 1000 gallon totes. 55 Gallon drums. I believe they all have impact resistant PP caps/bungs. They are all made by different suppliers. They all carry different chemistry. They all are...
Peckett, By geothermal fluid, I assume you mean a system using some sort of anti-freeze or oil based transfer fluid, and not solely water? I also understand that there is an EROSION problem with aluminum that would weather a flowing system rather quickly.
By "corrosion resistance" I was...
I'm researching Geothermal Heating energy and I am curious as to why hundreds to thousands of feet of coiled Polyethylene piping is preferred over perhaps a buried aluminum heat exchanger. Aluminum has great corrosion resistance (unlike copper) and thermal conductivity. In my opinion, using a...
Shame on me, but CRC is not in my library. I'm interested not so much in the full density iron oxide, but more in the incidental surface iron oxide. Thanks for the post.

I'm looking for information on electrical properties of iron oxide (FeO3) relative to other materials (metal and nonmetals), such as silica, nickel, steel, etc... Does anyone know where I may find such information?

Good welds create an integral product. It is possible, though, that if the two halves are poorly welded or are of dissimilar material, that the weld is purely mechanical at the joint, perhaps there is a solvent that can infiltrate the porosity at that joint and dissolve the weld before the more...
Gymmeh, Thanks. This is along the lines of the route was begining to think. Getting deep rooted answers to customer requirements may not lie in the hands of the first line of interaction. These sales people have SALES on the brain, and follow a certain personality type for being extroverted...
This gravity feature makes sense, but it will be the smaller particles that will not fall and the bag will be responsible for catching these. Your bag efficiency should be rated at this particle size, not for the bulk that doesn't even reach the bag. Does your permitting specify a particle...
I posted this in a different forum, but it dawned on me that IT implementation of new software systems probably suffer the most from this. What tips, tools, best practices are used to completely extract information from the customer to find out what the customer REALLY needs, despite what...
I would come completely clean with your coworker. Ask him directly what his plans are. More than likely he's just fishing... and sometimes it takes a lot of fishing to catch what you want, so he may very well be with you for the duration. To be careful, though, rather than replace your...
A quick check to determine what should be on the list is to establish the part defects that can be attributed to the mold. Those PMs should be high on your list. I recently had a client "learn" that their cooling channels are completely fouled with calcium deposits, and have been for some...
It sounds like you're on the right track in your experimental thoughts. For references on how to coat cords, you may wish to do a search on coated wire and candle making. Patent searches on such processes would direct you toward companies that may specialize in such equipment. Try...
It sounds alot like what roker is saying. That third one in series sounds more like it is to protect from upstream disruptions when changing between the two in parallel. So essentially, at any given time, you only have 2 operating in series, with one stand-by. This makes sense.... As far as...
Big question. As you probably already know, filters are dynamic in terms of efficiency. The more the cake builds up, the more efficient it becomes at particle retention. This said, filters in series, you are building the cake on the first filter... and that is the filter doin essentiall ALL...
Glycerine is extremely hygroscopic, and will eventually absorb as much as 40% water (I believe) just from humidity. This could affect the performance. In addition, as btrueblood adds, it's a simple enough hydrocarbon to be food source for microcritters.

bvanhiel,
You are exactly right, and I should have stated it more clearly. I am an engineer working on a project to basically improve on the marketing/sales ability to extract such information. I suspect consultants in the biz face many of the same obstacles as marketing/sales do when dealing...
For contract work, that's great. I'm dealing with non-contract, no obligation type of work, where if I want to make a sale, I need the "REAL" requirements, despite whatever the (potential) customer tells me.

I'm involved with a project where one of the common (mis)conceptions is that the customer "doesn't know what they want." I was just wondering if anyone else out there has learned this to be the case, where in initial discussion, the customer appeared to want one thing, but upon delivery, they...
Some of these may be a little dated, but may be useful.

rcooper,
Thank you for this perspective. I will be sure to keep my boss fully in the loop if there is any reality to this talk.
