We have a 25 gallon vertical code vessel (with R stamp)that was fabricated without a jacket. We want to add a steam heating system on the bottom third of the vessel. We want to wrap 3/8" copper tubing around the tank. In order for us to do that, we need to remove the namplate (which sticks out...
I presently have a polymer water desolventizer unit that I take my product from. I then take it over to my Hobart 4146 meat grinder which acts as a dewaterer and compacts my polymer to a size that is great for drying. The screw in the meat grinder has rusted out. Hobart does not make the...
Can anyone point me in the right direction for codes or standards on painting within Chemical Plants? Specifically, I am after piping paint requirements and color schemes. Thanks.
Can anyone point me in the right direction for correct piping design on relief headers? Specifically, the preferred method for entry into the header. Top entry versus 45 degree lateral entry? I do not need specifics on back pressure or relief valve design. Thanks
Electrocoagulation through the Powell Water Systems reaction chamber produces several distinct electrochemical results independently. These observed reactions may be explained as:
A. Seeding resulting from the anode reduction of metal ions that become new centers for larger, stable, insoluble...
Generally, Y-strainers are used with gases such as steam or air. Basket strainers are used with liquids. A Y-strainer will offer more pressure drop than a basket strainer since its free straining area is less. As a strainer becomes clogged to the point where the OAR of the strainer approaches...
I agree that these operating requirements are not very demanding. Can you tell me what OD and wall thickness the tubes are? Without a superheater, corrosion and expandibility should not be a problem, allowing for even re-design of the tube arrangement. Heat transfer should vary between types...
I have found a very simple way to accomplish what you desire: By turning all lines into PLINES, you can then use MPEDIT (Multiple Polyline Edit) and increase the width of all selected lines within AutoCAD. Once this is done, you then export your selected drawing as a .wmf file. Once in Word...
You might want to look into a tray with a three-dimpled periphery to minimize contact with the tray deck for fouling or corrosive conditions. One place I know of:

Usually the pressure is for the rating of the tube. In our case the exchanger has even seen some polymer buildup. We connected our hot cyclohexane to the exchanger. It cleaned the exchanger with ease. I have heard of a material called GRUBs which works very well and does not need to be...
