Thank you. We only have air for the reactor do you know of any heater/blower combos that will supply 350-400F air at 500-800scfm?

Thank you

Thank you. Any idea why ISO specifies no aluminum for 32.5% urea (AdBlue brand)

I'm looking for the best material with high corrosion resistance to 32.5% urea, that also has high thermal conductivity to be used in a heat exchanger. The urea will be in the tube side, pumped in at 60F and heated to 350F. Therefore, the tubes will initially contain urea liquid then after...

Thanks for the replies. Yes it's an H2S, water, and ammonia I believe. There's no hot water source or gas source so air is the only way, using some sort of immersion air heater. There are the portable kind that supply 10KW/1000cfm but only reach 100-150F. This is not a typical heat...

We have acid water with only some properties known. We need to boil this at 5gal/hr and capture the vaporized air at the top. The concept is a vertical heat exchanger. The acid water will come in from the bottom at 70F, enter the tubes, and will be heated by hot air. The vapor will rise...

thank you paddingtongreen, Do you know of any inexpensive companys that can run an FEA for me?

Hi I'm looking for assistance in calculating stresses on a lifting clamp. Disc dimensions: 6 foot diameter, 6 inch thick Clamp dimensions: 6"x1/2" rolled to disc OD (two halves) Clamp bolts: six 7/8" bolts (3 per side) I attached a picture for clarity. So far, I have calculated hoop stress...

Thanks for the input everyone. Cannondale and btrueblood, Yes we currently use a Cat pump 6020 on our trucks with 1-2 guns per pump. Roughly 30GPM and 800 psi on each gun. Our current gun is a 1950 design made with 304SS 3/4" SCH-40 seamless pipe (1.05" OD, .824" ID). Much larger than the...

No seams. We will be welding the inlet and outlet tubes to the main body

Hi, I am designing a high pressure wash gun using a Cat 6020 pump. P = 1000 psi Q = 60 GPM The gun will look similar to this: http://www.gardnerdenverproducts.com/assets/0/180/146/196/3e5967b6-7800-4c81-a676-4138a0dbe0dd.PDF We currently use a 1950 vintage gun made from 1" 304 tube, so the...

Thank you. I am shooting for 5:1 depending on the weld strength of the aluminum. I am looking for the strongest filler/base combo to give us the highest weld strength.

Thank you. Found some in the 30 GPM range. We may have to build our own with aluminum.

Hi, I am looking to purchase 10 new guns for our pressure washers, but am limited due to our existing pumps. The highest rated pressure washer I can find is here: http://www.northerntool.com/shop/tools/product_200402932_200402932 It's rated for 2500 psi and 30 GPM. However, our Cat pumps are...

The unit requires an input voltage of 24VDC-240VAC
