    Bolt Head Pattern identification

    Unclesyd, thanks for the help. I think we found what we needed. Have a happy holidays. Kurt.

    Bolt Head Pattern identification

    I knew about the three lines being grade 5. We're looking for the vendor to prove that we don't buy from them, so this time it is important (at least to us).

    Bolt Head Pattern identification

    thread404-241995 I looked through the thread above and could not find the attached bolt head in any of the links. We are asking our nut and bolt suppliers if they know who made this bolt. A customer of mine found this in their product and are asking their suppliers if we recognize this. It...

    316 versus 430 SS application

    We're processing crystalline destrose. We don't weld the screens in, the screen folds and essentially snaps into place.

    316 versus 430 SS application

    No, the speeds in the centrifuge pretty much set them in (~1200 rpm). Metal ends up in the process if something goes wrong, usually a plow tip goes a little deeper than it is supposed to.

    316 versus 430 SS application

    The greater ferromagnetic is what we're after, so that magnets down stream capture anything that may be shed in the centrifuge. The corrosion resistance isn't a concern, as the product is not that corrosive. If the ductility isn't that much less than the 316 we're currently using, we should be...

    316 versus 430 SS application

    Where would I find relative differences between 316 and 430 stainless? I have a basket centrifuge that we currently use 316 SS perforated screen and wire mesh backing that we want to consider using 430 series stainless due to the higher magnetic property (food grade application). The question...

    Loking fo a low flow/low NPSH Pump

    Gear pump may not be able to handle the lack of viscosity. We use them in heavy solid syrups and they do not pump water, may be because the solids increase the clearances too much. I've always stayed clear of progressive cavity as I've heard the liners can sometimes come loose in big chunks...

    Business Travel

    Don't know that my old company had a travel policy or not, but I flew from Ohio to Manchester, UK, about 8 times in a six month period for a start up. The third time over, I flew a USAIR(line) that was horrendous compared to the normal flight I booked. The next time I was offered that...

    Is Posting Dilbert Cartoons Ethical?

    Is it wrong to post those three comics on my door? I am the department manager, after all. . .

    Loacation of makeup for cooling tower

    agf, certainly letting the tower overflow is an easy solution. Anymore, though, the cost of water is increasing, especially treating before going to the city or river (or where-ever). That's why I've generally seen CT that try to avoid constant over flow. We didn't use cooling water in many...

    Loacation of makeup for cooling tower

    I would think that if it is injected into the supply side of the cooling water loop, the lag time on the controller could be so long that control could be difficult.

    LEL measurement within a process tank

    Yep, you're right. EO has the ability to explode from 3% to 100% concentrations. There are specific "probes" that can detect EO only, or am I daydreaming?

    When to use Sanitary/Food Grade Piping

    My determination would be how often do you plan on taking your system down to sanitize? If it is frequent (once a week?), I'd go with the sanitary fittings since they are easy to disconnect and reconnect. If your process is continuous with little chance of contamination (due to acidic nature...

    LEL measurement within a process tank

    We have a system here on an enclosed filter and dryer that measures for O2 only. I wouldn't worry about measuring for LEL since if there in no oxygen, no kaboom. We have a slipstream off of the positive side of a blower that measures for oxygen and returns the stream to a lower pressure area...
