My company is starting down the road of getting a water treatment machine NSF 61 certified for use in drinking water systems. Being in charge of the manufacturing facility, I would like to know what requirements we will need to meet to get the certification. Has anyone been through the...
I am designing a small ancillary water system for a brewery and am using a membrane contactor that has sanitary connections on it. The tri clamp connections with the bead groove are straight forward. However, the contactor also has 4 ports meant for gas flow under a vacuum. Those ports look...
Let me start by saying I am an ME, not ChemE, so please bear with me. My company builds mass transfer vacuum dehydrators for machine lube oil. We use random packing in vacuum towers in all of our designs. Over the years we have always designed round vacuum towers using Sch 10 pipe. The packing...
I am working on the design of a vacuum vessel that is 41" high and oval in cross section. The end radii are 5.75" with a 13" wide mid section. So the ovsl is 24.5" overall length and 11.5" wide. The material is 1/4" thick steel, but haven't settled on the grade yet. We have made many of these...
Hello all and Happy New Year!
At my first employer out of school we always added ECO's as a sheet to the actual drawing that was being revised. The ECO would be 8 1/2 x 11 with all of the usual information and stayed attached to the drawing forever. The problem I saw was that far too many times...
For many years, my company has installed on/off SPST toggle switches in the conduit box(peckerhead) of 115V motors up to 1 hp with no reported failures. A man in our shop says there is a code stating that 1 hp is the limit for this configuration. In the past, when we went above 1 hp, we have...
Hello All!
I am working on quoting a system to inject ammonia and/or hydrazine into a boiler makeup water line. The customer has specified that one of the pumps be dual use standby with a diverter valve before the pump relief valve. I'm having trouble finding anyone that is willing to quote a...
Hello All!
My employer has started quoting treatment of various gas and water streams that involves the use of deionized water. I don't have any experience using DI water, but understand it is corrosive and a leach agent. A couple of the systems I am laying out are small with low flow rates and...
Hello All!
I've got a 12 ga 304 stainless steel sheet that has one edge cut to a radius of about 140". It's forming the top of an outdoor industrial power unit, so its pretty big. Since it's the top of the power unit, I want to edge roll it down 90 deg to create a 1" high lip to seal out rain...
My company currently fabricates the stainless hydraulic tubing for all of our standard machines right on the assembly line. Looking to reduce costs, I was wondering if our method is typical of medium to high volume manufacturing and if there is a methodology to enabling the use of prefabricated...
My company based in Kansas City is preparing to quote design and construction of an extensive hydraulic system for a civil project in California. Review and sign off by a registered PE in California is required should we win the bid. Can anyone out there share any PE consulting rates for...
My company fabricates lubricating oil conditioning equipment and every machine uses various sizes of custom fabricated stainless steel tubing. We currently cut the tubing to length on a band saw. This is going to become inpractical as we are moving to a new facility that will put the band saw in...
I'm in the fluid power industry, but posting my question here because it has to do with Skydrol. Does anyone happen to have any information regarding the compatibility of Loctite Vibra-seal 517 with Skydrol? I've got a call in to Henkel, but who knows when I'll hear back from them. Thanks!
Two years ago, I posted a comment regarding how much better I thought Solidworks is over Inventor. That comment stirred up quite a few responses, as you can imagine. Two yars later, I am now fully convinced that Solidworks is the better package and I've finally convinced the owner of my company...

I have worked most of my twenty year career at small companies and, as a result, have been havily involved in quality assurance. During that time, I've always been able to resolve quality issues with vendors with one or two meetings and clarification of my employers expectations. But, I'm now...
My company has built custom fluid conditioning skids for many years using welded pipe. Now we want to create a few standard production units with welded pipe and fittings. I was wondering how other companies deal with the tolerance stackups inherent in these kinds of assemblies and the fact that...
Well, after having the misfortune to use Inventor for the past 6 months, after having spent a year using Solidworks, I'll have to say the later program is much better to use. In typical Autodesk fashion, you have to have a doctorate in Inventor to get it to do what you want and check their...
We've got a bitmap logo inserted into our drawing template. The .bmp file is located within our Inventor Project, so Inventor should be able to always find it. However, on many of our drawings, the bitmap appears to get copied everytime we save the drawing. Each saved file shares the filename of...
Anyone have a guess as to why the features I create and publish to Content Center don't show up when I want to use them in a part file? I published them to the Features group in CC. Inventor 2009. Thanks!
